[Updated at 3:19 p.m. ET] Two patients who were brought to New York-Presbyterian Hospital Friday have been discharged and one has been admitted, the hospital's public affairs office said in a statement.
The three people were brought to New York-Presbyterian Hospital/Weill Cornell Medical Center Emergency Department as a result of a shooting outside the Empire State building shortly after 9 a.m., the hospital said.
Other victims were brought to Bellevue Hospital after the shooting, which police said left eight wounded and two dead, including the gunman.
Police initially said nine bystanders were wounded in an exchange of gunfire between shooter Jeffrey Johnson and police. That number was later revised to eight.
Police killed Johnson as he pulled a gun on them while trying to flee the scene where he fatally shot a former coworker, Police Commissioner Ray Kelly said.
The gunman apparently had a longstanding dispute with the victim over workplace harassment allegations, police said. Both men had filed prior complaints.
[Updated at 12:16 a.m. ET] New York Mayor Michael Bloomberg praised police and civilians for their quick response to a shooting outside the Empire State Building on Friday morning, which left two dead and nine injured.
"There is no doubt that the situation would've been even more tragic except for the extraordinary acts of heroism," Bloomberg said in a media conference. "New York City is the safest big city in this country but we are not immune to the national problem of gun violence."
Gunman Jeffrey Johnson, 53, killed one person before he was shot to death outside the busy tourist destination on 34th Street and Fifth Avenue in a chaotic scene just after 9 a.m., Police Commissioner Ray Kelly said. In addition to being home to a popular tourist destination in Midtown Manhattan, the area is also a busy commercial district.
"I saw people running and I didn't know what happened. I thought it was a celebrity spotting," said witness Rebecca Fox, who was on her way to work when the shootings broke out. "It was a very surreal scene."
Fast Facts: The Empire State Building
The victim was Johnson's former coworker at Hazan Imports, where Johnson was a designer of women's accessories until being laid off last year.
As Johnson attempted to flee the scene, a construction worker across the street alerted two police officers, who pursued him up West 33rd Street, Kelly said. As Johnson pulled out a .45 caliber pistol, the officers opened fire, killing Johnson. It was unclear if Johnson managed to shoot a round.
Nine others were wounded or grazed in the exchange of gunfire, Kelly said. They were taken to local hospitals where they are expected to recover.
"Some may have been accidentally shot by police officers," Kelly said.

Another proud moment for the NRA
No ideology involved... More like disgruntled citizen gets cheated on by girlfriend.
You people are joking, I assume. If you don't understand (1) the difference from a ban of handguns in NYC and a law preventing the purchase of handguns anywhere; (2) that making it illegal to purchase handguns would greatly reduce shooting because PEOPLE WOULD NOT BE ABLE TO BUY GUNS, then you're actually fools. Making heroin illegal reduces the number of heroin users.
And for the guy who's worried about armed thugs in your house? I guess you'd get shot. Luckily, that isn't likely to happen to you. Nobody wants to rob your trailer.
This is a governmental false flag attack aimed at us citizens to make us scred of guns
Three cheers for the NRA and guns!
Absolutely!! Cause when the thugs start shooting we can protect ourselves.
Perhaps we can do the politically incorrect and lock up lunatics. Instead of thinking the psycho babble ndustry ever actulaly cures any of them.
The NRA? Really?
Guns are illegal in New York, over the NRA's objections, and violence still happens there. The only thing that New York gun control accomplished is disarming the victims.
Too bad the gunman didn't realize that NYC has stiff restrictions on carrying weapons. I bet if he'd known about their strict gun laws, this never would have happened.
Yup, more of the "lone wolf" meme will be coming soon. Just another "asset" doing the will of the NWO. Just watch it now, Bloomberg will "save us" from ourselves again with more nanny state crap!
I bet another WHITE MAN!!!!
OWS at it again.
right... because OWS people sure do love their guns. why don't you wait for the bodies to cool before spewing baseless allegations
I am trying to remember the last time there was a shooting like this in the UK ? if you make guns illegal other than to those who really need them you can enforce much harsher penalties for carrying \ possession. The majority of gun crime is perpetrated against other criminals so you restrict the control of guns you eliminate a large amount of the ambiguous shootings that occur in the US. You will never 100pcnt stop these crimes but stricter control will surely help reduce them.
"a majority of crimes are perpetrated against other criminals" so you're saying all these people in line were criminals? And as another poster stated, NYC has some of the strictest gun laws in the United States: it is illegal to carry or transport any loaded firearm in the city unless you're a cop. A lot of good those laws did for that one woman who tragically lost her life. You're right, you're never going to eliminate these types of crimes, but I think a lawfully armed citzen should have the right to shoot back. Making guns illegal only takes them away from the law-abiding citizens; you think criminals care about gun laws? The only reason there weren't more victims is because that area is CRAWLING with cops. Otherwise, we'd have a different story here, one that could have ended better with an armed ctizen.
Tell me more about how criminals follow the law...
And for those people who fall under the "Failure to stop 100% of gun-crimes", I guess we'll just sit there and wave our Johnson's at the Bad Guys. Assault with a Friendly Weapon?
The US is much larger than the UK, it doesn't make sense to compare and is ignorant.
The gunman was white? I must've missed this fact. And how do the authorities know this is not related to "terrorism" already? Come on reporters, dig!
Oh lordy!! I can just hear bloomberg now.."We must get rid of ALL guns for your safety!" They will stop at nothing to see us defenseless and vaulnerable.
To: YourBusiness, I live in poverty stricken upstate NY too. But all we have to do is drive down the road to bag our dinner. No guns,no hard work. Just very expensive car insurance.
OMG can you people blow a homicide out of proportion or what? While the person who was killed was a tragic event, the shooter was also killed, which means an easy case clearance for some Murder Police. And then you say that the president was notified of this event...WHY!!!!!! I gues you better tell him of a homicide that occurreed in Miami, or Dallas or San Diego also...And then you continually keep updating and having "special reports".....once again WHY!!!!!! It was just a homicide people, Damn
This is not a standard homicide. Perhaps this guy had an agenda for killing one person, but if that was the case, you dont randomly shoot 9 others. This was a terrible terrible act, and yes, the president should know about it
Is this the start of the civil war?!
@mental health professional
I completely agree!!
