[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.

Each year, about 4 million people visit the building's two observation decks. At more than 1,453 feet tall, the landmark building reaches more than a quarter-mile into the sky.
NYC, one of the largest gun free victim zones in the country. Blood on Bloombergs hands for not allowing law abiding citizens the right of self protection.
a) it's an isolated incident. It happens. I'm sure there's NO correlation that NYC is the safest large city in the US and has the tightest gun laws...I'm certain there's no correlation at all.
Also, Unless Bloomberg pulled the trigger, in no way is this "his fault" come on....That's hyperbolic transferal of blame.
someone got fired and went back to take care of those who fired him, simple as that, thats sad....being in HR nowadays is not safe....
Instead of bickering about gun control, why don't we try to find out why Americans want to kill each other so badly and see if we can't do something about THAT issue.
Do we know if the gunman was American?
For focus on this being an American issue shows your ignorance of the world.
Tom, I'm not sure I understand what you're trying to get at. I'm only attempting to discuss the American piece of the problem here. I'm absolutely ignorant of gun violence problems in other countries, so I won't attempt to discuss them.
I do have a decent handle on the violence issue in the US however, and have a number of ideas on how to remedy the situation. It's kind of common sense, but it's not necessarily "easy"
just a second guys, the fact that someone got shot even when strict gun laws are in place in one city IS NOT a reason to loosen gun laws elsewhere. that's like saying if someone dies in a crash with an airbag in his car, we should start taking them out of other cars. it's almost like you are celebrating this tragedy in your reverence for the gun culture.
More like your comment is just as much an overreaction to whats actually being said as you are accusing others of being.
They that can give up essential liberty to obtain a little temporary safety deserve neither safety nor liberty-Ben Franklin
I don't own a gun and I never will, but it scares me that Americans want to just throw away their right to own them without considering why that right was granted in the first place. Look at North Korea, a people oppressed by an extreme government.
The North Koreans don't own guns, they are powerless. Only the military owns guns.
@Cole They gunman could have gotten the gun outside of NYC because of lax gun laws and then brought it into NYC. Laws in one city are not enough if the surrounding areas don't take steps to prevent acts like this too
White males are the real terrorists. Their terrorist cell is called the GOP
Comment reported. Your hate has no place here.
Are you forgetting about the five people that were shot? Stop with the gun control and politics. My heart goes out to all of those innocent people and their families.
How did this guy have a gun in New York? They are not allowed there......
Give us our 2nd ammendment. IF we had the right to CCW then people would think about what they do not knowing who has a gun on themor not . Good job NYPD
Just because people could conceal doesn't mean that would stop the 'crazies" or criminals from stopping their crimes. Look at other countries and the hundreds of years before that when someone whole stole or did some other petty crime has their hand cut off. They know the consequence but they take the risk anyway.
I don't think the Gun Laws are the be all end all. Look at Australia. Their laws are very strict and their deaths by firearms is much lower per capita and overall than ours. Personally I think it's a our culture more than anything. Americans anymore are so desensitized to death, crime, etc. We care more about what the rich and famous are doing than true news. To top it off the family structure / responsibility in America is horrendous.
I did my duty for the U.S. Army, have not touched a weapon since and see no need to.
I want all weapons strictly controlled, and TAXED to Pay Victims. I also want amunition strictly controlled and traced.
Guns kill people – the only bright side is that its most likely that they will be members of the killers family.
No one needs a assalt weapon for hunting, in fact they are not very good for that. Hand guns are the worst, the only people who have them need props for their personal insecurities.
Thanks for your service, and I completely agree with you!
I want cops to respond to a 911 call in a REASONABLE amount of time. Until stopping a crime becomes a higher priority than worrying about my expired registration, or if I am wearing a seatbelt, then your concerns would be more vaild...
BS! You were not train to kill! I am also a veteran. I was train to defend this great nation against all enemy both foreign
and domestic. You must have been in admin.
I have many guns, and they have never killed anybody. And since they all could be used in an assault, I guess they are all assault weapons. I have used many of the assault weapons for hunting, and they work very well, sir. I am very happy to hear that you do not need firearms, as you clearly do not sound stable enough to wield them responsibly.
guns are illegal in nyc
So...your saying the only ones that have guns are the criminals......Yes I feel MUCH MUCH safer with that thought!
Thank you New York. Now I definitely feel safer. Ban on guns? Yeah sure.
N R A. Let the gun sales skyrocket and the senseless slaughter continue. Sincerely yours, Satan
Gun makers flood the black market with guns to remain profitable. Those laws don't stop gun makers from doing this. We need to stop that, not more laws on gun owners
it doesn't matter what laws are on the books, gun makers flood the black market with guns to remain profitable. That's what needs to be addressed and the NRA offer no help to do that because they want crooks to have illegal guns to make it necessary for them to keep their guns. I have no problem with the 2nd amendment- but the NRA could work with law enforcement on this issue and they refuse
@ yuri pelham
Funny how gun related crime has being going down even though gun sales have "skyrocketed". It's a damn shame that facts get in the way of your hate.
@ Nancy M
The only black market flooding of guns I have seen evidence of is from Eric Holder and the "Fast and Furious" campaign...
How about paying respect for the deceased and their friends/families instead of immediately using this incident to fuel your own political agenda.
How about we do both? Yes.
