[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.

CNN censors posts that contain no profanity.
Why on earth would they do that?
This person had a 0.45 caliber pistol and some of the wounded bystanders (none too critically- some were just grazed) were accidently shot by police. Just imagine (to the gun nuts) if the shooter had an automatic weapon. I would say that this is actually supportive of NY's automatic weapons regulations (as opposed to CO). I agree with the gun nuts that you can't stop crazy or stupid. But you can stop arming them with automatic rifles with hundreds of metal piercing rounds.
You cannot legally buy an automatic rifle in the United States.
automatic firearm: gun continues to fire as long as the trigger is pulled and there are still rounds in the magazine.
semi-automatic firearm: fires one shot per squeeze of the trigger – holding the trigger down does not cause more rounds to be fired.
It is currently illegal for any US citizen to own an automatic firearm produced after (I think) 1986. Automatic firearms manufactured prior to that can be legally owned upon completion of federal paperwork and paying a $200 fee per firearm.
Please learn a little about your topic before posting. thank you.
You need to educate yourself. A .45 caliber pistol *IS* a semi-automatic gun. It automatically loads another round in it's chamber for the next shot.
The guns used in Colorado were also "semi-automatic". A "fully automatic" gun fires continously when the trigger is pulled. Non of the guns used in these two cases were fully automatic.
I blame this on Obama. The nation is hurting...no jobs, stress, the future is bleak, its enough to drive people mad and do extreme things.
This country needs a lift but with O in the white house and not caring about turning around this nation....
He does not care about jobs, wages, or bringing back American to all its glory. This administartion thinks its doing a great job......delusional at best I'd say.
There is no end in sight and things are only going to get worse. Blame the President.
Ahhh!!! He was laid off a year ago from the news story.
To all you haters of gun rights...this was because Obama couldn't get this guy a job.
19 people shot overnight in Chicago (Aug 23rd), shooting in NY.......not enough for stronger gun controls??!! guns dont kill people, people kill people....what evs. We have amongst the loosest gun controls and gun ownership screening...its a ticket for gun rage and gun killings....yet the media has shows like American Guns andGun Smokes, supoprted by dollar doling lobbyists.....some on guys!!
You complete and utter twit. NYC and Chicago have THE strongest, (and most ridiculous), gun laws in the nation. Stronger gun laws won't prevent this sort of thing from happening. Safety, education and common sense are the only thing
that will ever prevent and/or save anyone, not MORE LAWS.
Outlawing guns really worked in Norway.
Is the NRA paying you by word for insulting folks opposed to guns. With anger like that and a gun in your hand, i would be concerned. Do get your point across, in a civil and educated manner though.
CaptainObvious, the most obvious thing about Norway is that they donot have shootings and gun violence on a daily basis or a few times a day. Good point though.
earnmyvote: If you even read my post, you'd see that strong gun laws in Chicago and NYC don't work. Also, I'm not insulting someone opposed to guns, I'm insulting someone who doesn't know what they are talking about.
yeah since all you idiots want to take away the right to bear arms lets get rid of the freedom of spech so no one has to hear you dumb remarks
Wow. If the cops really shot people that is a big problem. Overzealous much?
This guy must have had an eye patch or a beard, some distinguishing mark that would have given away the fact that he was a 'bad guy.' 'Cause you know all bad guys in a delusional persons head are distinguishable. Pay no attention to the fact that there are thousands of cops in NYC. They, the gun totters, are blood hungry and want to be the 'hero.' Bruce Willis stars in their delusional head. Maybe we should issue out courtesy guns, that way, when they hear shots fired, everyone will pull out there gun and look for the person with the gun and start firing. Sound smart? No? I don't think so ether.
And all gun owners are "blood hungry and hero" type indistinguishable from each other, right? So those law abiding non street gun carrying who just wants to collect antiques or use their guns for sports and recreation are also blood hungry and wanna-be heroes. Is that what you mean?
Yes, Rice. That's exactly what I meant. I meant a antique collector walking down polishing his collectable should have had the foresight to load his gun and shoot.
Guns are illegal in NYC... how did this happen!
LOL... Thats what I was thinking!
Actually they aren't. You need a permit, which isnt easy to get.
Really....that's all you can come up with? MORON!
?GUN CONTOL NOW
SPEECH CONTROL NOW!
If you want to outlaw gun ownership (Second Amendment in the Bill of Rights) nothing will stop outlawing Freedom of speech (First Amendment).
Don't cherry pick which rights you like and which you don't.
Gun control is still out of control!
Gun control would not have stopped this. MOST guns that are used in a crime are NOT registered, so how would gun control, which is ONLY about registering guns stop those who use illegal guns? No, political correctness is why these shooting keep happening. People are afraid to speak up when someone is sending up all sorts of red flags in their behaviour. We all look the other way until that person explodes and kills people and then everyone says "why didn't anyone notice he was a nut?" Well, you did, you were just too much of a coward to say something.
another public shooting – amazing in a city that controls your soft drink consumption, how you feed your new born baby, and where you ingest second hand smoke but yet the thought of controlling guns on it's streets is anathema to most.
They have gun control you ignoramus! Handguns are illegal in NYC! Read!
They should make laws outlawing shooting someone. That will solve the problem right? Right ??
And NY HAS gun control within the city. Gee how is that working out?
It is illegal to have a handgun in NYC. So how did this person get to use a handgun when it is banned there? I guess his criminal mind did not heed to that law, either.
You cannot legally carry concealed in NYC. So they have already taken care of that. If you want to illegally though you can, like this guy did. Look at Chicago, another city that bans LEGAL carrying of firearms for protection. So basically NYC sucks.
The solution is not more gun control, it is legalizing soft drinks, how you feed your baby and smoking.
I want a Free country, not a necessarily a safe one (as if that is even possible).
That's it, I'm leaving this American stinkhole. I think I'll go to Norway or something. No one ever shoots anyone there...Oh, wait...
Norway is a great country to live in. I have been there many times over the years. However, I hope you have the means to afford living there. Norway's cost of living makes CA look like utopia..............
what we need is more gun laws after all it was against the law to carry a 45 in nyc also shooting people and police it was against the law to kill your former boss maybe one more law would prevent this happening in the safest city in america giv me a break bloomberg you are the nutcase in nyc
