[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.

Would you care to explain just how that is so? Or do you just want to spout off? Right wing freak.
Just another upstanding US taxpayer excercising his 2nd Amendment rights...Is this what our Founding Fathers had in mind when they wrote it?
Why do you assume he actually pays 'taxes', since half the country does not pay US Income taxes. But that is another topic. I believe the founding fathers had in mind that we are allowed to have guns, so that if a lunatic is running down a street shooting people, ONE of the many people who are legally armed could shoot them before he/she takes the life of 9 people.
What the Founding Fathers had in mind was for citizens to be able to protect themselves from loonies like that guy. If everyone carried a handgun I think the likelihood of these displays of violence would diminish. Why would one fire into a crowd knowing most of them had a weapon? Everyone in Texas carries a gun and you don't hear these types of massacres occurring there on a monthly basis. I"m not sure what the answer is, but banning anything certainly does not and has not worked in the past.
2nd amendment, in no way, at any time, under any interpretation, grants a right to murder with a firearm or fire it indiscriminately at people who mean one no harm.
they need to say what race this person was.
Probably the 'usual'.....if u know what i mean....
White old man = Grumpy old troll...
@Christina..I don't believe stronger gun laws will stop this. Those that get the license and proper training to carry a gun aren't the ones killing people. Its those that obtain guns illegally that do it.
You do realize that the Dark knight shooter obtained his guns and ammo legally. Moron
1 out of ten thousand shootings by someone who obtained guns legally, stop the madness!!!!!
Let create a fund for the Empire State Building.
@Bxgrrl No we can not talk about gun control now...Until the ban manufacturing, sale and possession of any and all firearms including police and government is what is being discussed then no no discussion.
We humans are not mature enough for that. We are always invading other tribes and stealing their crap.
Why isn't there more gun contro is this country
I guess the shooter didn't know that NYC has strict gun laws. If he did he would have never done this.
I would feel safer with a brown person on an airplane than with a white person in a public place. Gun-toting psychos!
That is straight-up disgustingly racist. Replace white with any other race and read it again. Tell me it wouldn't be offensive. Why is it okay to use language like this when it's directed at whites?
yet it is conservatives that stock up on guns, and want zero gun control. how interesting
I am from India- in USA for a temporary business purpose..and shocked to see innocent citizens killed like this every week. In India, gun laws are very strict and such shootings rarely..very rarely happen. And we are a third world country not comparable to US in terms of might and prosperity. Yet, I have very rarely come across any citizen randomly and mindlessly attacking fellow citizens- total stranger- just like that in my country. On the contrary, people unite and help strangers in times of any natural calamities or terrorist attacks from across the border. I will be back home once I complete my work in US (in 1-2 months) and just want to urge the sensible people in US to do two things- make stricter gun laws and restore culture of social & family bonds and a sense of belonging to a good and caring community- so that your people don't shoot their own country-men.
Listen JD.....agree with your comments in general, but wish India would fix all their many many problems which cause death to the masses;
there are no gun issues but the "British and their control-points/local Maharajas and appointees" have been replaced by the 1% of the population who do NOTHING for the rest of the 99% & in fact "shoot" and hurt the 60% poor by treating them like slaves.....in addition nothing is done with pollution, filth, etc. which further "shoots" the population....so you guys don't need guns!
good comments, but way easier said than done. Gun control issue is very complicated here. A thriving business that is partially why it is so difficult to control and change. Plus the whole cultural cowboy, amercian independence history. What we need is to change our culture a little, so it is less based on greed and material wealth. Then people would have a different focus on their life and not become so enraged and go off and kill others.
International tourists were screaming? Didn't anybody tell them that any nincompoop can get a gun in the U.S. and start shooting? Welcome to America!
Everyone can get cars too which doesn't make all drivers bad people, listen to your ridiculous logic.
England's statistics got "manipulated" when ithe facts came to light, They are not lower. Keep reading.
Does anyone know if this was terrorist related? I'm hearing mixed reviews...
No, someone who worked there...
Are these people any more or less dead or injured if it was a terrorist?
Workplace violence much the the Fort Hood shooter sep different............
another day, another mass shooting in america. nothing new anymore
It's sad, Americans make jokes of it all the time because it is just everyday life here in America. We have forgot just how awful it is to lose precious life.
Sadly, this is exactly what I too would have written. In our country, we have come to the point where this is no longer "news", but rather has become a commonplace occurence. Gun ownership and gun use are glorified, extreme views and "my or the highway" mentality dominates, there is no longer consideration for others or other's perspectives.
was he white american , middle eastern muslim or somebody else ? These things seem to matter these days.
