[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.

My suggestion to end Chicago's out of control shootings (19 shot in 8 hrs yesterday): invite all gangs to one mass shoot out. Isolate them. Let them take each other out. No innocent by standers hurt. They are so bent on shooting rival gangs, make it easy for them. Gangpalooza, all gang bangers invited. Bring your guns (as if they need to be asked). Have at it. What a lovely dream....
This didn't happen in Chicago though.
@Rae I know it didn't happen in chicago. Just sayin
I'm not surprised more of these crimes are occurring. It is usually because of the economic downturn that people are resorting to violence. As a person's economic situation deteriorates, that person is more likely to turn to extremism.
@Wilburr – And what empirical evidence do you have to support that this is a result of economic downturn? I have not seen any empirical research that shows violent shootings follow economic downturns. Higher levels of theft/burglary tend to follow economic downturn, but violence tends to be related to other factors. It is always more complex than just one variable leads to another.
That's BS their economics had nothing to do with these shooting, the guy in Colorado wasn't having financial issues he was a college student studying engineering. The skinhead had been crazy for years. I guess they are broke, so they decided the best way to fix this is to take their grocery money and buy thousands of dollars worth of firearms. I have another thirty. How about theory are just crazy cowards. Oh that doesn't make sense.
NRA reaction Marty is probably along the lines of: How's that gun ban working out Bloomberg? Oh wait there was a shooting and the man has to be chased away by a brave unarmed guard? Not well I guess.
nothing to do with the NRA – New York is a gun free zone
Not quite sure what you are talking about. New York, and in particular NYC has one of the toughest gun laws in the nation with a police force probably second to none....Take your politics out of it, nuts will find a way to do what they do, and no law on the books meet that end....
But they still need to get access to guns. Have you tried to get 5 lb's of plastic explosives on line recently?
Tony ya don't need high tech explosives to hurt people. That's just naive.
it's not about NY's gun laws its about the other states that NYers get guns from with lax laws and then are sold illegally. Everyday there seems to be some sort of shooting in the country. Who are we protecting by not strengthening gun laws? This is insane! I guess when enough "regular" citizens are murdered it will be addressed.
You need guns or explosives to hurt more than one person at a time, before you can be brought down by unarmed bystanders.
@newyork, that's exactly the point. "THEY" will get guns somewhere else.
Outlawing guns will not stop the glorification f violence in he USA.
Outlawing lorification of violence in music and movies will have a far quicker impact.
Did the legal speed limit keep you from speeding to work this morning?
We have a world culture of disrespect for the law, at all levels., from the top down to the least.
Not A chance of taking that bet,we know he is white by the code words,terrorism not involved.
think about it people...... when have you seen a gun stand up by itself and shoot a couple rounds into grandma????
STUPID INSANE MORONS shoot people for no good reason except they are sad cause someone made fun of them or saw it in a movie.
Society should fight back,its OUR right to bare arms,period.
It is obviously stupid to think that giving people guns won't cause them to use them. These mass murders will continue to happen until we get rid of guns. I must admit I am not shocked that someone from Wyoming would say something like this though. Is your neck red?
STUPID INSANE MORONS want to put guns in the hands of STUPID INSANE MORONS who will use those guns to murder people. What part of this don't you understand?
If Semtex was as available as guns are, there would be bombings daily in every town in the US.
i thought having a gun in NYC was already banned, I guess this proves gun control doesn't work at any level. Criminals will get a gun if they want one.
Allowing unstable citizens to arm themselves with military assault rifles and semi automatic handguns (who are increasingly shooting people in public venues), lowering middle class workers wages, cutting social safety net funding, writing hundreds of bills to control womens reproductive rights, placing voter suppression laws in place, limiting healthcare availability, and cutting all enviromental regulations. Congratulations GOP, you're plan to regress the US into a bloody third world Country with a clear division of wealthy and poor citizens is coming to reality.
Wallster, it's true much of today's violence can be blamed on wall streets tanking the world economy, but just as much cn be blamed on Obama rewarding them for it with bailouts and bonuses.
However, it's both parties. Romney will sell what remains of personal wealth and Obama will give it away for free to foreign interests. He just gave 1.5 million jobs to foreigners and now drivers licenses as well.
Both parties will contribute to the violence of displaced Americans scrw-dover by their "representatives".
thank you for this overlooked news MyFeelsMatter. Scorecard Update: NRA +19, people -19
How do you know they were Christian?
We need to start a government program that starts evaluating suspected psychos. What's all this NSA money going towards?
"no apparent link to terrorism" – If this is not terrorism, I don't know what is. I think these "news" organizations need to get their head out of you know what, and start reporting news as they are.
This the NRA's way of making sure there are more seats available for US citizens on international flights
CNN is racist, doesn't report the 19 shootings by blacks in Chicago yesterday.
No, shooting poor black people is never reported. Same with abducting one of their kids, you have to be a blue-eyed blond to be their news poster missing child.
