[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.

The Empire State Building is one of the most famous skyscrapers in the world, and one of New York City's best-known tourist attractions.
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.
I would suspect that the perp had weapons in violation of applicable laws, and because of those same laws, there was no bystander intervention. Laws do NOT take guns off the street and out of the hands of criminals. They take them out of the hands of the good guys.
And where were all those bystanders to protect the people in Colorado where the gun laws are lax? Or in past Texas shootings etc...
Just what we would have needed- 10 others shooting on a street at eachother with 100,000 nyc bystanders all around. Idiot.
And just who are the "good guys?"
BZ... You're woefully uninformed.. in Aurora Colorado it is illegal to carry a concealed weapon. How lax is that? And truth be told the bystanders were probably hit in the barrage of police gunfire.
Would you feel differently about gun control if you lost a loved one to this type of crime, or if you yourself were injured?
Gun toter is correct. Look up the laws. He went into a theater that was gun free too. If I carry open carry style into the theater, I've just throw 20.00 into the trash, I will be asked to leave and if I don't, I go to jail for trespassing. If I conceal carry, I've broken the law. If I were conceal carrying and killed the shooter, I'm now facing murder charges.
In Indiana, we seen a drop in violent crime each time we lifted anti-second amendment bans/regulations. Not an increase like some would like you to believe. Look at areas where the handgun bans were thrown out. Less crime, not more. If we could live in a world without handguns, neat. I'm a large man with a quick fist. What about my 5'1" 110 lbs wife though? You keep your silly ideas to your self and don't own a firearm. When you're in trouble and seconds count, call 911 and hope for the best.
It is amazing to me that people are on here commenting on America's fun laws and are turning this into a political forum. Did anyone read the headline that 10 people were shot? 10 lives. Maybe there's more to focus on here...
I work around the corner from the ESB and it's very scary to think this happened so close.
GUN laws...not fun laws. Guns are not fun.
JB... I work around the area as well and I agree, it is very scary to know that anytime some wacko will just start pulling the trigger. However, thank god not all 10 people were shot to death. It could've been a lot worse.
I feel for the victims' families and friends. I give my condolences to them.
The reason this has become political, is because people are neither blind, nor stupid. There's more to the recent violent activity than a bunch of unstable foaming-at-the-mouth mad-men. There's an objective here. It's pretty obvious. Ever heard of the manchurian candidate?
stroud... we don't have more crime than we did before. NYC is one of the most populous cities in the world and it is not possible to not have any crime here. Actually considering the population and the size of this city, crime here is very low.
IT"S AMAZING HOW THIS WORLD . GOS PROTECT US
This country spends a lot of money to protect us against foreign terrorists. Yet, we have more of our own citizens killing us and we do nothing to to protect us from them. In this country it seems that our 'well regulated militia' is run by the NRA and not the government.
Self protection on a personal scale is individual responsibility. What do you propse we each have a personal cop looking after us at all times?
Dang it! God fearing gun advocates were not near the building to rush in and help defend these unarmed victims. That's why we need to expand gun laws to allow folks to carry concealed weapons so they can help whenever someone decides to unload a clip on innocent people!
We don't know who shot the other victims. There were lot of police gunfire... Though not as if it would ever be reported if the uninvolved victims were shot by cops...
Gun control should not only be a ban to posses a gun, but it should be a control of where the guns are and who can get them. GUNs should belong only to POLICE or MILITARY, and instead of trying to find someone smoking a joint (weed) which will not do any harm to anyone, police should focus more on illegal gun sales.
Are NYC citizens allowed to have tazers? ... I'm guessing probably not.. Also, concealed handgun laws of which I am a HUGE proponent only work if people actually have them and then carry. Many places and possibly the theatre do not allow concealed handguns... I only know a handful of people here in Texas that have one and most people don't bother.
Maybe gun control is a bit too easy of an answer, especially in a city where guns are pretty much completely forbidden by law already. Allowing the unarmed guard that chased the suspect away to carry a weapon might just have been a better answer, even a deterrent. My thoughts and prayers go out to the victims and their loved ones.
True... the guard should've been given a gun or at least put a Police officer rather than a guard next to one of the most popular buildings in the world.
Tiem to run out and buy more guns before you can't legally.
Well looky looky how well gun control worked here in the Empire State. 10 shot before anyone could respond. Yeah I feel MUCH safer being disarmed... NOT. I wonder how Bloomingidiot is going to spin this tragedy.
You're jumping to conclusions that he obtained this firearm legally. You don't know that, so stop jumping all over the legal methods of obtaining a firearm. Wait to see what the facts say.
1) guy is clearly a liberal. conservatives are better shots. and it is a co-worker dispute....so its a work place violence like major nadal in fort hood.
2) 19 people were shot in Chicago...last night. cricket noises from the media. Rahm is on it though, he said don't shoot the kids...I guess it is ok to shoot everyone else..just don't shoot the kids.
3) Maybe the guy was on edge, no cigarettes, no trans fats, no salt, popcorn under attack and then the big gulp is taken away....he snapped.
4) NYC has some of the toughest gun laws in the country – bloomberg said the cops should go on strike until people turn in all the guns. Think this guy would have turned his in?
Guns. Guns. Guns. We love our guns. Stay tune, more shootings and more killings to come.
But I thought that guns were outlawed in NYC. Oh....I see your point. Guns should be outlawed everywhere. Then there wouldn't be any more shootings...........just multiple stabbings for you to rant about.
I don't know how this is possible. I thought Mayor Nanny took away all the guns. Oh, apparently he didn't get the ones that the criminals have, just the ones that the law-abiding citizens had.
Who said this guy way a criminal? Probably just another idiot who bought a gun, and has a mentality that tells him to solve problems with a weapon rather than using his brain. Every gun owners wet dream is to be able to play hero and shoot a bad guy. I still haven't seen those "responsible" gun owners come to the rescue in situations like this. Your point is worthless.
I think everyone should be required to own a gun, so we can shoot morons
We should also let every nation on Earth have ICBMs. Works for the small equation, should work for the big one too, right?
The target on your back is pretty large and obvious.
