[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.
Scenario if everyone was "packing" : Cops gets call for shots fired; people down. Pull up on scene, 5 people with guns shooting. Several don't obey (or don't hear) orders to put down their weapons. Quick, which ones the crook? Which one do they shoot first? Crooks don't wear name tags identifying themselves from other people and I doubt he will raise his hand.
Not exactly a good idea having everyone armed..especially from a cops point of view.
You watch too many movies. I suspect you think that all guns have an indefinite supply of ammo and that a person carrying a gun for defense could fire hundreds of shots?
So true! Lots of chance for innocents to get shot. If I was the cop I'd drive away and come back when it was all over & sort it out. Better than being accidently shot by some panic stricken plumber packing a .357 in his tool kit!
@mike how many hundred rounds did the CO theater shooter have??
This may sound outrageous, but this and all the other high profile mass shootings across the country are most likely gov backed, pre cursors to an imminent national weapons ban. The gov wants to take every single weapon out of the publics hands. So when they push new outrageous laws, and population control directives, the public will not be able to retaliate. The world is changing in a very big way, and we are letting it happen. California will be the first sate to go...
Totally agree. I'm not American so it matters in no way to me who is elected, but it does seem rather strange that all of these shooting are on the tail of an election and a gun law bill...just sayin
No, it doesn't sound outrageous, it sounds utterly stupid.
It's definitely a ploy to get more folk to join the NMRA. (National Model Railroad Association)
The media and the public are hoping the suspect was Muslim. It was probably another white guy with too many guns.
How is there "no apparent link to terrorism"? THIS IS TERRORISM!
Business as usual. Everyday in America and in all countries where America is occupying for total control is day of killing and a bloodfest. America=murder incorporated.
There are 270 million guns in this country. How many nutjobs? Plenty. So why is anybody surprised? Sadly, just another day in the US.
and how many legal gun owners did not go out and commit a crime with their guns?
Then what are they carry a concealed attack weapon for?
@Alex V and you must be not as witty as you think. Blacks don't name their kids Anna. Ronanna maybe but not Anna.
Latest from local news- shooter was fired from his job yesterday. Tried to get back into the office today to kill his boss. The building security stopped him, so he went outside to wait for his boss to leave (possibly when going for coffee break). The number of victims is up to 10 now.
GOD BLESS CANADA and our gun laws!
Yes I`m sure you are a crime proof country.
Could have avoided with better access to social service counseling with healthcare in general. People who are mentally unstable are the ones who shoot others. Go vote for republicans, you guys are nuts.
I don't think that there is any question that pulling guns out of circulation would drive the number of gun-crimes (and deaths) down. It would unquestionably make it more difficult to obtain a gun, even illegally.
The real question is, is gun control something we're willing to do?
Hey Gun control nuts Norway just sentenced killer of 77 to 21 yrs Wow in 21 yrs we get to see if he can break his record and oh I'm sure he won't get a gun due to strict gun control laws!
Actually he has been sentenced to preventive detention. Which is a polite way in Norway of saying he will never be released.
More than just a glance would make it apparent to you that that man is going to stay in jail until he rots. Instead of the American "parole" system, this man will be examined after the 21 years to determine if he is a threat to society, and let me assure you, he will be determined to be a threat. He will be in jail for another 5 years and the process will be repeated again and again for the rest of his life.
Looks like we all sort of piled on there, I think you gets it. Sorry for seeming a little pedantic.
He will never walk the streets in Norway again.
After the 21 yrs in detention he will get another 21 yrs.....
WE SHOULD BAN CAPS LOCK... hee hee
Amazingly the story below that 19 people were killed in Chicago in 13 minutes is less news that this....

Wait sorry... it took 30 minutes, not 13 to kill 19 people...
