[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.

Mordrud – of course not, but putting people are buying guns everywhere it's much too easy
Oh no, now those folks will have to defends gun owners again.
If these wackos are going to be shooting people, can't they at least pick better targets than random innocent people. Without naming names or organizations, there are plenty which come to mind lol
I love how gun advocates will take this opportunity to tell us that this is why we should have LESS gun laws. "See, they don't work." That is pouring salt in the wounds of the victims of a tragedy like this one.
See, told you we should ban soda bigger than 12oz...
Bloomberg's illegal gun control is a joke that only disarms law abiding citizens. Crime has DROPPED everywhere guns are allowed.
Not true...nyc has the lowest gun violence of any major city in the country....stop spreading disinformation hick.
This story is a lie. This did not happen in NYC. Everyone knows guns aren't allowed in NYC.
Hey Shevone, we call this 'sarcasm'.... The sarcastic part being that you can have the TOUGHEST gun-control laws in the country (Chigago) and even NYC and still have 'guns' magically appearing to be used by lunatics to kill people.
Now go back to your TV instead of going to learn something.
why are pro-NRA people sooooo offended all of a sudden???? Their guilty is the result of all the pro-gun comments. If guns are easily available – nuts will use them. If they are not available, then they cannot kill. I think most supporters of NRA are nuts anyways
so true. all the gun nuts are insane.
But doesnt NYC have some of the strictest gun laws in the USA? So just admit the strict gun law did not stop a nut from gettng a gun and killing someone. Its that simple!
How do you make them non-available? Do tell us how this magical fantasy works. When prohibition was in effect, how did that work out?
Would there be a house to house search?
You gun-control people are 'nuts' if you think making more laws will 'magically' fix the problem.
like narcotics, guns are freely available on the street. the nra has nothing to do with that. getting a gun is only a problem if you want to do it legally. prohibitions are ineffective. they just encourage a strong black market.
This is a mistake – New York has tough, 'progressive' gun control laws, so strict that hardly anyone who lacks political connections can even own a handgun there, so CLEARLY this really didn't happen.
don't be a tool.
BS. You can own a handgun in New York: the difference is that New York does not think that churches, bars, and schools are appropriate places to bring one. If 10 people had been shot in, say, Dallas, would you be making the same idiotic claim?
You can own a handgun in NY? It would probably take about 5 years to get a permit to 'own' a handgun, and even then it only allows you to keep it in your home, not take it out other than to travel with it in a locked box to a shooting range. Getting a 'carry permit' is next to impossible.
So please enlighten us as to how easy it is to get a handgun in NY?
CNN coverage has really gone downhill: spreading unconfirmed rumors; asking stupid questions of (or worse putting words in the mouths of) bystanders. We used to be confident we were getting the straight story from our newscasters. Now they seem not much better than the bloggers. Sometimes their behavior is humorous. Sometimes (as when I heard them announce that Gabby Gifford, someone I know personally, was dead), it is very harmful.
If you see a man wearing a turban and a long beard with a gun stuck in his belt, run for your life pilgrims!
What is the mayor doing now – don't just ask the presidential candidates – but try something. He was more worried about Big gulps than guns
Only law abiding citizens will obey gun laws. Anyone can get a gun privately without a background check. It's too late to restrict guns, as there are millions of privately owned guns for sale. The only way to solve this problem is to come up with a way of evaluating a persons mental health, and determining possible warning signs that someone is going to have a psychotic event. These people don't develop these issues overnight.
I think people are stressed. The press contributes to the stress. The weak ones in the population emerge to do tragic things like this. We need to chill on the political demagogy as well.
It is People in General that are all screwed up...It is EZ to pick up a gun...and go on a rampge...like living in some dumb video game...we have become a Nation of Violence...
