Mom who shot intruder inspires gun control foes

LOGANVILLE, Ga.A Georgia mother who shot an intruder at her home has become a small part of the roaring gun control debate, with some firearms enthusiasts touting her as a textbook example of responsible gun ownership.

Melinda Herman grabbed a handgun and hid in a crawl space with her two children when a man broke in last week and approached the family at their home northeast of Atlanta, police said. Herman called her husband on the phone, and with him reminding her of the lessons she recently learned at a shooting range, Herman opened fire, seriously wounding the burglary suspect.

The National Rifle Association tweeted a link to a news story about the shooting, and support poured in from others online, hailing Herman as a hero. The local sheriff said he was proud of the way she handled the situation.

"This lady decided that she wasn't going to be a victim, and I think everyone else looks at this and hopes they have the courage to do what she done," Walton County Sheriff Joe Chapman said Wednesday.

Herman was working from home Friday when she saw a man walk up to the front door. She told police he rang the doorbell twice and then over and over again. He went back to his SUV, got something out and walked back toward the house, a police report said.

Herman took her 9-year-old son and daughter into an upstairs bedroom and locked the door. They went into bathroom and she locked that door, too. She got her handgun from a safe, the report said, and hid with her children. At some point, she called her husband, who kept her on the line and called 911 on another line.

In a 10-minute 911 recording released by the Walton County Sheriff's Office, Donnie Herman calmly explained what was happening to a dispatcher. His part of the conversation with his wife was also recorded.

"Is he in the house, Melinda? Are you sure? How do you know? You can hear him in the house?" Donnie Herman said.

His wife told him the intruder was coming closer.

"He's in the bedroom? Shh, shh, relax. Just remember everything that I showed you, everything that I taught you, all right?" Donnie Herman told his wife, explaining later to the dispatcher that he had recently taken her to a gun range.

It wasn't clear from the recording exactly when they went to range and Donnie Herman told The Associated Press on Wednesday the family didn't want to talk about the shooting.

After Donnie Herman told his wife police were on the way, he started shouting: "She shot him. She's shootin' him. She's shootin' him. She's shootin' him. She's shootin' him."

"OK," the dispatcher responded.

"Shoot him again! Shoot him!" Donnie Herman yelled. He told the dispatcher he heard a lot of screaming, but he seems to get increasingly worried when he doesn't hear anything from his wife.

Melinda Herman told police she started shooting the man when he opened the door to the crawl space. The man pleaded with her to stop, but she kept firing until she had emptied her rounds, she told police. She then fled to a neighbor's house with her children.

The man drove away in his SUV. Police found the SUV on another subdivision street and discovered a man bleeding from his face and body in a nearby wooded area. Police identified the suspect as 32-year-old Paul Slater of Atlanta.

Chapman said the hospital asked him not to comment on Slater's condition, but he said he is not certain Slater will survive.

CBS Atlanta affiliate WGCL-TV reports Slater is on a ventilator.

Authorities have a warrant but haven't formally arrested Slater yet. They plan to charge him with burglary, possession of tools for the commission of a crime and aggravated assault, Walton County sheriff's Capt. Greg Hall said.

A phone number for Slater was not listed and it was not clear whether he has an attorney.

Authorities believe Slater targeted a home in another local subdivision but left when confronted by the homeowner, Chapman said.

Flu Kills 4 Seniors, Sickens 700 in Boston

An early and nasty flu season has prompted a public health emergency in Boston, where health officials say 700 people have been diagnosed with the cold-weather virus. Four Bostononians -- all elderly -- have died from flu.

"This is the worst flu season we've seen since 2009, and people should take the threat of flu seriously," Boston Mayor Thomas Menino said in a statement.

This time last year the city had seen only 70 cases of influenza, The Associated Press reported. And with flu activity likely to extend into March or even April, the number will only grow.

Menino said the city is working with health care centers to offer free flu vaccines, and he urged anyone with flu-like symptoms to stay home from work or school.

"This is not only a health concern, but also an economic concern for families," he said in the statement. "I'm urging residents to get vaccinated if they haven't already."

Eighteen people have died from flu in Massachusetts, one of 41 states battling widespread influenza outbreaks. Emergency rooms across the country have been overwhelmed with flu patients, turning away some of them and others with non-life-threatening conditions for lack of space.

The proportion of people seeing their doctor for flu-like symptoms jumped to 5.6 percent from 2.8 percent in the past month, according to the CDC.

Earliest Flu Season in a Decade: 80 Percent of Country Reports Severe Symptoms Watch Video

Northwestern Memorial Hospital in Chicago reported a 20 percent increase in flu patients every day. Northwestern Memorial was one of eight hospitals on bypass Monday and Tuesday, meaning it asked ambulances to take patients elsewhere if they could do so safely.

Dr. Besser's Tips to Protect Yourself From the Flu

Most of the hospitals have resumed normal operations, but could return to the bypass status if the influx of patients becomes too great.

"Northwestern Memorial Hospital is an extraordinarily busy hospital, and oftentimes during our busier months, in the summer, we will sometimes have to go on bypass," Northwestern Memorial's Dr. David Zich said. "We don't like it, the community doesn't like it, but sometimes it is necessary."

A tent outside Lehigh Valley Hospital in Salisbury Township, Pa., was set up to tend to the overflowing number of flu cases.

A hospital in Ohio is requiring patients with the flu to wear masks to protect those who are not infected.

State health officials in Indiana have reported seven deaths. Five of the deaths occurred in people older than 65 and two younger than 18. The state will release another report later today.

Doctors are especially concerned about the elderly and children, where the flu can be deadly.

"Our office in the last two weeks has exploded with children," Dr. Gayle Smith, a pediatrician in Richmond, Va., said

It is the earliest flu season in a decade and, ABC News Chief Medical Editor Dr. Besser says, it's not too late to protect yourself from the outbreak.

"You have to think about an anti-viral, especially if you're elderly, a young child, a pregnant woman," Besser said.

"They're the people that are going to die from this. Tens of thousands of people die in a bad flu season. We're not taking it serious enough."

Pruney fingers give us better grip underwater

WHY do our fingers do prune impressions when soaked? It could be an adaptation that gives us better grip underwater.

Fingers and toes wrinkle in water after about 5 minutes due to the constriction of blood vessels. This reduction in volume pulls the skin inward, but as the skin's surface area cannot change, it wrinkles. A study in 2011 showed that wrinkles form a pattern of channels that divert water away from the fingertip – akin to rain treads on tyres. The team thought that this could aid grip.

To find out, Tom Smulders and his team at Newcastle University, UK, timed people as they transferred wet or dry objects from one box to another with and without wrinkled fingers.

With wrinkles, wet objects were transferred about 12 per cent faster than with unwrinkled fingers. The time it took to transfer dry objects was the same regardless of wrinkles.

So why aren't our digits always prune-like? "With wrinkles, less of your skin surface touches the object, so there may be issues of sensitivity," Smulders suggests.

Cool change aids Australia firefighters

SYDNEY: Cooler conditions helped firefighters battling blazes across Australia Wednesday but up to 30 were still out of control, destroying a handful of homes and killing thousands of livestock.

After facing one of the highest-risk fire days in its history on Tuesday, residents in hard-hit New South Wales state woke to shifting winds that caused temperatures to drop significantly.

While the mercury topped 42 degrees Celsius (107.6 F) in Sydney on Tuesday, it was forecast to peak at just 25 degrees Wednesday, while the Victorian capital Melbourne was down to 20.

The ratings on many bushfires were downgraded with none now at the "catastrophic" level which signifies fires will be uncontrollable, unpredictable and fast-moving, and evacuation the only safe option.

But NSW Rural Fire Service commissioner Shane Fitzsimmons warned against complacency, with new fronts breaking out despite the colder weather and a total fire ban still in place.

"It is far from over when it comes to the threat to New South Wales," he told reporters in Bookham, a small village in Yass Shire west of Canberra where a fire has so far burnt out 16,000 hectares (40,000 acres).

"We need to sustain the vigilance today. We are not out of the woods yet, the risk is very real and there's a long day ahead and a forecast for a return to hot conditions toward the weekend and into next week."

More than 2,000 firefighters worked through the night tackling more than 140 blazes across New South Wales, Australia's most populous state, with 30 of those uncontained.

One home was earlier believed to have been lost in the state, at Jugiong, but Fitzsimmons said it now appeared to be an outbuilding or shed.

"It's a tribute to firefighters across the state that we haven't got any homes destroyed," he said.

"But we've seen significant agricultural losses already been tallied up, thousands of hectares of pasture and crops, and stock in the thousands lost."

New South Wales Premier Barry O'Farrell said an estimated 10,000 sheep had perished in the Yass area alone.

Wildfires are a fact of life in arid Australia, where 173 people perished in the 2009 Black Saturday firestorm, the nation's worst natural disaster of modern times.

Most are ignited naturally, but in Sydney's west three teenage boys were charged with deliberately lighting a fire in bushland on Tuesday.

Victoria state has also been experiencing extreme conditions with four homes destroyed and six people treated for minor burns or smoke inhalation in a bushfire in the farming community of Carngham, which was evacuated.

Authorities said the fire was now under control.

Prime Minister Julia Gillard said the federal and state governments were working together in the recovery effort and to support victims.

"Firstly, it's all hands on deck fighting the fires, dealing with the emergency, and then we move into the recovery phase," she said.

No deaths have so far been reported.

While it was initially believed as many as 100 people could be missing in the southern island of Tasmania after wildfires razed more than 100 homes over the weekend, police said there was confusion about movements during the crisis.

"We know there have been no significant injuries, which is amazing, and we are encouraged that we haven't found any human remains at this stage," Tasmanian acting police commissioner Scott Tilyard told Sky News.

Much of southern Australia has been enduring a summer heatwave and in the nation's arid centre the popular tourist resort of Kings Canyon south of Alice Springs was damaged after a blaze spread from the Watarrka National Park.

Opinion: Time for tough talk with Karzai

The last time Presidents Obama and Karzai met was in May in Kabul, when they signed a pact regarding U.S. troop withdrawal.

STORY HIGHLIGHTS

• Afghan President Karzai meeting with President Obama in Washington this week


• Felbab-Brown: Afghan politics are corrupt; army not ready for 2014 troop pullout


• She says Taliban, insurgents, splintered army, corrupt officials are all jockeying for power


• U.S. needs to commit to helping Afghan security, she says, and insist corruption be wiped out

Editor's note: Vanda Felbab-Brown is a senior fellow in foreign policy at the Brookings Institution. Her latest book is "Aspiration and Ambivalence: Strategies and Realities of Counterinsurgency and State-Building in Afghanistan."

(CNN) -- Afghan President Hamid Karzai is meeting this week with President Obama in Washington amid increasing ambivalence in the United States about what to do about the war in Afghanistan.

Americans are tired of the war. Too much blood and treasure has been spent. The White House is grappling with troop numbers for 2013 and with the nature and scope of any U.S. mission after 2014. With the persisting corruption and poor governance of the Afghan government and Karzai's fear that the United States is preparing to abandon him, the relationship between Kabul and Washington has steadily deteriorated.

As the United States radically reduces its mission in Afghanistan, it will leave behind a stalled and perilous security situation and a likely severe economic downturn. Many Afghans expect a collapse into civil war, and few see their political system as legitimate.

Karzai and Obama face thorny issues such as the stalled negotiations with the Taliban. Recently, Kabul has persuaded Pakistan to release some Taliban prisoners to jump-start the negotiations, relegating the United States to the back seat. Much to the displeasure of the International Security Assistance Force, the Afghan government also plans to release several hundred Taliban-linked prisoners, although any real momentum in the negotiations is yet to take place.

Vanda Felbab-Brown

Washington needs to be careful that negotiations are structured in a way that enhances Afghanistan's stability and is not merely a fig leaf for U.S. and NATO troop departure. Countering terrorism will be an important U.S. interest after 2014. The Taliban may have soured on al Qaeda, but fully breaking with the terror group is not in the Taliban's best interest. If negotiations give the insurgents de facto control of parts of the country, the Taliban will at best play it both ways: with the jihadists and with the United States.

Negotiations of a status-of-forces agreement after 2014 will also be on the table between Karzai and Obama. Immunity of U.S. soldiers from Afghan prosecution and control over detainees previously have been major sticking points, and any Afghan release of Taliban-linked prisoners will complicate that discussion.

Karzai has seemed determined to secure commitments from Washington to deliver military enablers until Afghan support forces have built up. The Afghan National Security Forces have improved but cannot function without international enablers -- in areas such as air support, medevac, intelligence and logistical assets and maintenance -- for several years to come. But Washington has signaled that it is contemplating very small troop levels after 2014, as low as 3,000. CNN reports that withdrawing all troops might even be considered.

Everyone is hedging their bets in light of the transition uncertainties and the real possibility of a major security meltdown after 2014. Afghan army commanders are leaking intelligence and weapons to insurgents; Afghan families are sending one son to join the army, one to the Taliban and one to the local warlord's militia.

Patronage networks pervade the Afghan forces, and a crucial question is whether they can avoid splintering along ethnic and patronage lines after 2014. If security forces do fall apart, the chances of Taliban control of large portions of the country and a civil war are much greater. Obama can use the summit to announce concrete measures -- such as providing enablers -- to demonstrate U.S. commitment to heading off a security meltdown. The United States and international security forces also need to strongly focus on countering the rifts within the Afghan army.

Assisting the Afghan army after 2014 is important. But even with better security, it is doubtful that Afghanistan can be stable without improvements in its government.

Afghanistan's political system is preoccupied with the 2014 elections. Corruption, serious crime, land theft and other usurpation of resources, nepotism, a lack of rule of law and exclusionary patronage networks afflict governance. Afghans crave accountability and justice and resent the current mafia-like rule. Whether the 2014 elections will usher in better leaders or trigger violent conflict is another huge question mark.

Emphasizing good governance, not sacrificing it to short-term military expediencies by embracing thuggish government officials, is as important as leaving Afghanistan in a measured and unrushed way -- one that doesn't jeopardize the fledgling institutional and security capacity that the country has managed to build up.

Karzai has been deaf and blind to the reality that reducing corruption, improving governance and allowing for a more pluralistic political system are essential for Afghanistan's stability. His visit provides an opportunity to deliver the message again -- and strongly.

PYONGYANG, North Korea Former New Mexico Gov. Bill Richardson said Wednesday that his delegation is pressing North Korea to put a moratorium on missile launches and nuclear tests and to allow more cell phones and an open Internet for its citizens.

Bill Richardson, Eric Schmidt arrive in North Korea

Richardson told The Associated Press in an exclusive interview in Pyongyang that the group is also asking for fair and humane treatment for an American citizen detained in North Korea.

"The citizens of the DPRK (North Korea) will be better off with more cell phones and an active Internet. Those are the three messages we've given to a variety of foreign policy officials, scientists" and government officials, Richardson said.

He is accompanied by Google Executive Chairman Eric Schmidt and Google Ideas think tank Director Jared Cohen on what Richardson has called a private, humanitarian trip. Schmidt, who is the highest-profile U.S. business executive to visit North Korea since leader Kim Jong Un took power a year ago, has not spoken publicly about the reasons behind the journey to North Korea.

The high-profile visit comes just weeks after North Korea launched a long-range rocket to send a satellite into space. Washington has condemned the launch as a banned test of missile technology.

Schmidt, who oversaw Google's expansion into a global Internet giant, speaks frequently about the importance of providing people around the world with Internet access and technology. Google now has offices in more than 40 countries, including all three of North Korea's neighbors: Russia, South Korea and China, another country criticized for systematic Internet censorship.

He and Cohen have collaborated on a book about the Internet's role in shaping society called "The New Digital Age" that comes out in April.

Using science and technology to build North Korea's beleaguered economy was the highlight of a New Year's Day speech by leader Kim Jong Un.

New red banners promoting slogans drawn from Kim's speech line Pyongyang's snowy streets, and North Koreans are still cramming to study the lengthy speech. It was the first time in 19 years for North Koreans to hear their leader give a New Year's Day speech. During the rule of late leader Kim Jong Il, state policy was distributed through North Korea's three main newspapers.

Holmes Played Childish Games After Aurora Carnage

As police confronted the movie theater carnage and a massive booby trap left behind by accused Aurora gunman James Holmes, the suspect loopily played with hand puppets, tried to stick a metal staple in an electrical socket and clamly flipped a styrofoam cup, according to court testimony today.

Holmes, 25, displayed the bizarre behavior once he was in custody and taken to Aurora police headquarters after the shooting that left 12 people dead and dozens injured, the lead investigator in the case testified today.

While being cross examined by Colorado public defender Daniel King, Police Detective Craig Appel was asked about the observations of two Aurora officers assigned to watch over Holmes in an interrogation room.

Appel said that to preserve possible gunshot residue, police had placed paper bags over Holmes' hands. One officer, King said, noted in a report that Holmes began moving his hands "in a talking puppet motion."

King asked if Appel was also aware that the officer "observed Holmes take a staple out of the table and tried to stick it in an electrical socket?" Appel confirmed Holmes' actions.

The officers also noted that they watched as Holmes began playing with an empty styrofoam cup, trying to "flip it" on the table.

While Holmes was carrying out his childish antics, police were puzzling over a complex booby trap Holmes had left behind in his apartment, according to testimony.

A gasoline-soaked carpet, loud music and a remote control car were part of Holmes' plan to trick someone into triggering a blast that would destroy his apartment and lure police to the explosion while he shot up a movie theater in Aurora, Colo., according to court testimony.

FBI agent Garrett Gumbinner told the court that he interviewed Holmes on July 20, hours after he killed 12 and wounded 58 during the midnight showing of "The Dark Knight Rises."

"He said he rigged the apartment to explode to get law enforcement to send resources to his apartment instead of the theater," Gumbinner said.

His plan failed to prompt someone into triggering the bombs.

Gumbinner said Holmes had created two traps that would have set off the blast.

The apartment was rigged with a tripwire at the front door connected to a mixture of chemicals that would create heat, sparks and flame. Holmes had soaked the carpet with a gasoline mixture that was designed to be ignited by the tripwire, Gumbinner said.

"It would have caused fire and sparks," the agent said, and "would have made the entire apartment explode or catch fire."

Holmes had set his computer to play 25 minutes of silence followed by loud music that he hoped would cause a disturbance loud enough that someone would call police, who would then respond and set off the explosion by entering the apartment.

Gumbinner said Holmes also told him he rigged a fuse between three glass jars that would explode. He filled the jars with a deadly homemade chemical mixture that would burn so hot it could not be extinguished with water.

World's oldest pills treated sore eyes

In ancient Rome, physicians treated sore eyes with the same active ingredients as today. So suggests an analysis of pills found on the Relitto del Pozzino, a cargo ship wrecked off the Italian coast in around 140 BC.

"To our knowledge, these are the oldest medical tablets ever analysed," says Erika Ribechini of the University of Pisa in Italy, head of a team analysing the relics. She thinks the disc-shaped tablets, 4 centimetres across and a centimetre thick, were likely dipped in water and dabbed directly on the eyes.

The tablets were mainly made of the zinc carbonates hydrozincite and smithsonite, echoing the widespread use of zinc-based minerals in today's eye and skin medications. Ribechini says there is evidence that Pliny the Elder, the Roman physician, prescribed zinc compounds for these uses almost 250 years after the shipwreck in his seminal medical encyclopaedia, Naturalis Historia.

The tablets were also rich in plant and animal oils. Pollen grains from an olive tree suggest that olive oil was a key ingredient, just like it is today in many medical and beauty creams, says Ribechini.

The tablets were discovered in a sealed tin cylinder called a pyxis (see image above). The tin must have been airtight to protect its contents from oxygen corrosion.

"Findings of such ancient medicines are extremely rare, so preservation of the Pozzino tablets is a very lucky case," says Ribechini.

The cargo of the wreck, discovered in 1989, is rich in other medical equipment, including vials and special vessels for bloodletting. This suggests that one of the passengers may have been a physician.

Japan summons China envoy over islands dispute

TOKYO: Tokyo summoned the Chinese ambassador for the first time under the new nationalist government to "strongly protest" against the presence of official ships in waters around disputed islands.

The foreign ministry said it told China to stop sending the vessels to the area around a chain controlled by Japan under the name Senkakus, but claimed by China as the Diaoyus.

Deputy minister for foreign affairs Akitaka Saiki met with Chinese ambassador Cheng Yonghua from around 11:00am (0200 GMT) on Tuesday to protest against Beijing's dispatching of four ships Monday, the ministry said in a statement.

The ministry on Monday lodged a protest with the Chinese embassy by telephone.

It summoned Cheng on Tuesday for the first time since conservative Prime Minister Shinzo Abe came to power on December 26 with promises of assertive diplomacy to confront a confident China.

The ministry last summoned acting Chinese ambassador Han Zhiqiang on December 13 to file a strong protest after Beijing sent an airplane to the area. Japan scrambled fighter jets in response.

It was the first incursion by a Chinese state aircraft into Japanese airspace anywhere since Tokyo's military began monitoring in 1958.

In the meeting on Tuesday, Saiki "strongly protested over the Chinese public vessels' entry and staying for a long time inside Japanese territorial waters, as well as strongly demanded that such incidents do not happen again," the foreign ministry statement said.

Cheng responded by reiterating China's claim over the islands, but said he will report Japan's protest to Beijing, the foreign ministry said.

Cyanide poisoning kills lottery winner

Urooj Khan, 46, won $1 million before taxes on an Illinois lottery scratch ticket in June.

STORY HIGHLIGHTS

• Urooj Khan, 46, won $1 million before taxes on an Illinois lottery scratch ticket


• He died suddenly weeks later; authorities first ruled his death "natural"


• Revisiting the case, they found he died of "cyanide toxicity," a medical examiner says


• Chicago police are investigating, but haven't made any arrests

(CNN) -- One day, Urooj Khan literally jumped for joy after scoring a $1 million winner on an Illinois lottery scratch ticket.

The next month, he was dead.

The Cook County medical examiner's office initially ruled Khan's manner of death natural. But after being prompted by a relative, the office revisited the case and eventually determined there was a lethal amount of cyanide in Khan's system.

"That ... led us to issue an amended death certificate that (established) cyanide toxicity as the cause of death, and the manner of death as homicide," Chief Medical Examiner Dr. Steve Cina said Monday.

Why did Khan, an Indian immigrant who was described as a well-liked, hardworking and successful businessman, die? And who is responsible?

Finding that out is now up to the Chicago police. No arrests have been made.

"We are investigating it as a murder, and we're working closely with the medical examiner's office," Chicago police spokeswoman Melissa Stratton said Monday.

On June 26, Khan was all smiles at a 7-Eleven in the Rogers Park section of Chicago. Surrounded by his wife, daughter and friends, he held an oversized $1 million check and recalled his joy upon playing the "$3 million Cash Jackpot!" game, where tickets sell for $30 apiece.

"I scratched the ticket, then I kept saying, 'I hit a million!' over and over again," the 46-year-old Khan said, according to a press release from the Illinois Lottery.

"I jumped two feet in the air, then ran back into the store and tipped the clerk $100."

The plan, he explained, was to use the money for his mortgage, paying off bills, a donation to St. Jude Children's Research Hospital and investing more in his dry cleaning businesses.

"Winning the lottery means everything to me," Khan said.

He would have to wait a few weeks to collect his actual winnings, which amounted after taxes to about $425,000. According to CNN affiliate WGN, that check was issued July 19, but Khan never got to spend it.

The next night, Khan came home, ate dinner and went to bed, according to an internal police department document obtained by the Chicago Tribune. His family later heard him screaming and took him to a local hospital, where he was later pronounced dead, the paper reported, citing the document.

That's where the Cook County medical examiner's office came in, investigating Khan's death because it was "sudden and unexpected," Cina said.

At the time, there were no allegations of foul play or evidence of trauma. So, following the office's policy, Khan's body underwent what Cina described as an "external examination (and) basic toxicology testing," neither of which turned up anything abnormal.

So the medical examiner ruled Khan had died of arterial sclerotic cardiovascular disease -- which encompasses incidents like heart attacks, strokes and aortic ruptures -- and that his manner of death was natural, according to Cina.

A few days later, a family member approached the doctor who had examined the body "and said they felt uncomfortable that it was being ruled a natural and they suggested that we look into it further," the chief medical examiner said.

"So we did that," he added. "Forensics is not a static field. If new evidence comes to light, we'll revisit cases."

That meant more in-depth toxicology tests. In early September, new screening results came back indicating cyanide in Khan's blood. With that, the official manner of death was changed from natural to pending, Cina said, and Chicago police got involved.

In late November, a more detailed blood analysis came back showing "a lethal level of cyanide" and Khan's death became a murder case.

Chicago police haven't offered details, including a possible motive, about what they call an "ongoing investigation." Talking briefly with CNN affiliate WBBM and the Tribune, Khan's widow described her husband as kind and exemplary.

Jimmy Goreel, who runs the 7-Eleven where the winning lottery ticket was sold, offered similarly glowing comments about Khan.

"I would never think that anybody ... would hurt him," Goreel told WGN. "(He was a) nice person, very hopeful and gentle (and) very hardworking."
