[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.

Ok, does this guy get his NRA membership revoked for 30 or 60 days? What is the policy?
Well it's sure obvious that the New York strict gun policy worked. This and the Yankee stadium shootings and the Chicago shootings yesterday prove strict anti gun laws do not work.
Meanwhile, there is a report on South Korean TV about a nut job running around with a big knife rendomly stabbing people. Do you think Korea will collect all kitchen knives? Not likely.
The cats out of the bag on guns fellas, they aren't going away anytime soon. Get over it already. Move to europe maybe if you don't like living in fear?
all he needed was a job a job a job where are all the jobs
He only had the gun because he is a member of a well ordered militia. NOT
If only NY had strict gun laws this would have never happened...wait, um...yeah they have those. I'm all for listening to the reasoning for more gun control laws if and when someone can logically explain to me how they will help when the hundreds of ones on the books already didn't stop this.
nyc is the safest large city in the country because of those strict gun laws
What an incredibly stupid thing to say.
We have strict gun laws in Canada and we had a firearms registry which permitted the government to take away PROHIBITED weapons.... Everyone can own a riffle or shotgun if they took a firearms course and the government requires another permit for someone who wants to buy a gun or more guns so that someone reponsible (police, clergy, judge, doctor) will need to vouch for you to get 1 or more guns. It didn't stop spree killings like at the Montreal Polytechnic or Dawson College or Eaton Center. I can name 3 spreee killings that happened in 30 years.... I can name 2 spree killings that happened in the US in the last MONTH. For all you gun nuts, do you get the point ??? more guns available increases the odds of gun violence. As we speak, I can get access to half a dozen hunting firearms and go on a rampage, but like most Canadians, I dont because my life is not hopeless. Spree killings happen out of desperation, someone screaming for help and people not listening, people working hard and losing everything only to see the rich bankers and brokers get bonuses for losing the money that they entrusted them with..... suffering the consequences of someone elses greedy actions and seing noting done about it. When SOME people are pushed to their limits, they either go out with a wimper (suicide) or a roar (rampage).... and the media gives attention to the rampage and no one fixes the underlying problem of inequality which the media should keep in the front page. Fix societies problems and the gun violence will fix itself... you dont have to believe me, just look at Canada's social programs, they have helped to maintain a balanced society...We are not Socialists, we just care about each other as a society...... and remember SOCIALism / SOCIety seem close in meaning..... the oppposite of the word is INDIVIDUALism ...... The U.S. can either be 300 million individuals fighting for their own interests or 300 million people working together for everyones interests......... Health care is a good start, any decent society cares for their sick, anyone else thinking otherwise is thinking about their own self interests.... be it doctors, insurance company making a profit, stock holders of pharmaceuticals or insurance company. Profit is good, but at what cost ????
3 sprees killings in 30 years? You must not be familiar with the Canadian bran of Hells Angels...what Providence do you live in?
Canada also has a small fraction of the population of the US. That might be an important factor.
you obviously haven't been sick lately. Try working in the healthcare....moved to the USA.....Go Romney/Paul
I can go get a knee replacement or appendectomy or facelift TODAY should I so desire. How about you? What's your waiting list on those three operations?I can also go and get a gun of my choosing from any sporting goods store. It's called FREEDOM you ignorant, brainwashed, socialist cog. Just shut up and continue being America's attic.
This is not an incident of terrorism? How come
What else this crazy white male was doing? Why Americans are not held responsible for terrorism? In recent weeks, this is third major incident of terrorism .... Americans vs. Americans. We should all grow up
Actually, if you go to police one dot com, you'll see pictures of the downed shooter. He is black. Try not to wear your ignorance and racism so proudly.
If this whole point is to ban guns, why not just shut down the factories that produce them and confiscate all existing guns including the police. lets go back to the time of swords and lancse and to the time when a mans word and his balls were the things that conunted...
Not to mention his/her ability to spell and articulate him/herself.
Yeah, everybody with swords....EXCEPT a corrupt, crooked government. Real smart.
HA HA HA HA HA HA HA
I was wondering when a wingnut would try to blame Obama, and shrubbos recession for all the other wingnuts out there killing innocent people. Putz
aaah, more 2nd amendment terrorism. Guns are a menace and are creating major terrorism in this country. They all need to go.
So, a disgruntled former employee shoots ONE person and the overzealous police shoot NINE in their botched response. Let's see if the media focuses on that minor detail...
As previously thought. Simple Murder. With bystanders injured. Enough said.
I think NYPD did more damage in this one than the shooter. Chalk one up for NYC's finest....
Another member of a well regulated militia exercising his second amendment right. What? You mean he is not in a well regulated militia?
The well-regulated militia argument is a red herring. The Bill of Rights protects the rights of the citizens. In other words, the second amendment is not a grant of governmental authority.
