[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.

Was he a Right Wing Christian nut, an Islamic Fundamentalist nut, or just a plain old nut?
For everyone who is talking about gun laws not being effective needs to realize you are talking about local law. Local law is meant to punish but it doesn't really effect the supply and availability of guns that are meant to kill. We need to have a federal dialogue about gun control. NYC's or any other states gun laws can only do so much to PREVENT these types of things because they don't effect the supply. They only punish offenders. We need a federal dialogue about gun control!
Yes, a good dialog will keep criminals from getting a hold of guns.
Would it make you feel any better if these people were pushed out of windows or run over by a delivery truck?
That is bogus logic. You can't push 10 people out of a window. Also, it's much easier to take a life by pulling a trigger. Psychologically killing somebody with your bare hands is much tougher to do. We don't need to make mass killings any easier.
"They only punish offenders."
You're right, let's punish everyone!
Can't agree with you more!
65 million people own firearms and don't kill people. But of course those people don't matter. Let's punish the majority because of the actions of a tiny minority. This is the kind of country you want Mark.
And what will you do about it when someone rents a delivery truck and plows through a farmers market? The reality is nobody who claims to be for gun control is really in favor of anything but a total ban on all firearms. As soon as someone gets a hold of a few revolvers in a bag and kills a few people with it then that will be it. Total and complete ban on all of them.
What is going on in the US, it was never like this in the past. These mass shootings are becoming the new trend in America, it seems as though mass shootings are the new it for 2012
Say hello to Barak Obama, better known as da Kingfish. He and his comic sidekick Andy (Biden) and his lawyer, Calhoun are really wrecking the country.
Julian, sorry to point out, but shootings have been happening since guns were invented. Before guns it was done with knives and swords and prior to those such weapons, probably rocks. The media and the 'instant' updates we have available now because of technology are the things that make it seem as if it's a "fad" or more common place nowadays. Also, we've never had more people in the world.
Just a reminder.
19 people were shot in Chicago last night, 8 in a single incident. Did CNN have breaking news for that?
CNN doesn't care about black people
Yeah, but the gang-bangers make this a nighlty occurence in Chi Town. When it happens according to a schedule, it will not be breaking news.
We only pay attention to mass shootings in places that are unexpected. Duh.
Exactly.. my point.. very curious about these "reported" incidents recently.. especially when people are shot all over the country.. in multiples but we never hear about thsoe shootings.. NYC isn't immune and although we're approaching 9/11 doesn't mean knee jerk reactions need to occur.
Amen. 13 shot in 30 minutes on the south side.
if a tree falls in the woods...
thats cuz no one cares about chicago
That is truly horrible! It speaks to it not being "Breaking News" since the high numbers of Chicago dead has become an everyday reality there.
OMGosh... How is that possible? It's not legal to carry a handgun in Chicago, and very difficult in NYC. When will criminals start respecting these "Gun Free Zones" and attack people who have a chance to save their own lives?
I agree with Zelli.
No, because Chicago is another gun-free utopia.
The reason CNN didn't report 19 people shot in Chicago is because this incident is a selfish act of violence with no intended target except random people. The Chicago shootings were gang related, and come on let them sort it out themselves, do you really care who controls what corner for their illegal enterprise?
yes it might effect there penny stock value
Really? 509 chicago students were shot in an 18 month period. These are kids, not a label. Some were as young as 9.
How about when they want to come in and control YOUR corner?
The city's dramatic drop in crime has been attributed by criminologists to policing tactics, the end of the crack epidemic and the results of legalized abortion approximately 18 years previous
Freakonomics 101 – NYC drop in crime rate may not be attributed to better law enforcement, but instead, legalization of abortion and the decrease in mothers not willing to care for their "accidental" children.
That is true... Most people that have abortions would usually be w/ a lesser element. Thus producing lesser element kids who would be more susceptible to committing extra crimes...
The reason is less complicated. RUDY GUILIANI brought crime down
These incidents bring out the worst in commenters. No sensitivity, respect or thoughtful comments. Only jokesters who like to laugh at their own silly, out of place, stupid comments. You are not being clever or cute. You just hide behind your keyboard and say things that would get you hitting the ground, or worse, if you dared to say them to a person's face. We wonder why people have become desensitized to killing another human. There is no hope for America..not because of any politician, but because of Americans themselves.
Your problem, Crazy, is that you are not smart enough to see where the heart of the problem lies. You must be a lib ??????
This couldn't have possibly happened since New York is such a peaceful, gun-free haven! Thanks, Bloomberg!
I'm sorry, can you explain your logic? Is a ban not the same as having them be illegal? So now someone who knowingly violates the law, violates it again with murder. Yet that's not illegal enough for you? Is this not the perfect scenario of "if you ban guns only bad guys have guns"? Are you seriously that blind to it?
If a consertative doesn't like guns, he doessn't buy one.
If a liberal doesn"t like guns, he wants to ban them for everyone.
That is so right! Locks on most doors are only there to keep honest people honest. Any fool can break in through a window.
At this rate soon guns will be banned, How long Moron like NRA justify this killing.
NRA is more dangerous then OSAMA, Gun kill more people the 9/11 didA
Drugs kill more people than guns and they are illegal and regulated by the federal government. How's that working out for you?
Good thing the internet has no idiot buffers, You would be using a pencil and paper if they did.
People with evil minds kill people, it is not the gun it is the holder. Look a Mexico, gun control and only corrupt government and cartels have guns. Taking away guns from the mass majoity would only make us slaves of the government which what they want. A socialist government.
People kill people. The method is the variable. And before you say that only guns are used in mass murders, I suggest you look up the machete murders in South America and Africa and the mass murder of 5 people in China by one man with a knife.
Ever notice that ALL of these mass murders are committed in places where the shooter has the best chance of NOT encountering anyone else with a gun? Yea, disarm everyone and then only the criminals will have them. How is that working out in the African countries where the UN disarmed the people and now there are mass murders every day by "government" troops?
Another win for Bloomberg and his Facist gun-control policies. If you are ever in NYC, don't count on a bystander to save you. You minus well just get on your knees.
Colorado has concealed carry laws–some of the most open in the nation. Why didn't anyone there shoot back?
He could have gone on for an indefinite time because the accessibility of weapons dwarfs in comparison to the underlying lack of social cohesion in America that really generates these incidents.
The police killed the suspect. The system worked as far as that is concerned. Do we really want the solution to be other bystanders shooting up the scene to save the day? Seriously?
Yes, because there are just SOOOO many examples of the bystander jumping in with his/her gun to save the day. Just so many. Talk about a baseless argument.
You sir are an idiot
Because most establishments ban concealed weapons! Colorado law allows establishments to ban ALL weapons. The two theaters I have gone to have signs out front prohibiting firearms inside. How well did that work in Aurora?
More notches in the grip for the NRA! Hope they are proud of themselves!!!
I strongly doubt the shooter was a member of the NRA, but we'll see. Most likely an Obamunist, or someone from Obama's unemployment line.
Why don't you try some actual critical thinking. Haven't you noticed yet that ALL of the mass shootings occur in areas where the shooter is unlikely to encounter anyone else with a gun??? ALL OF THEM! And when you disarm the law abiding citizens, who will be there to protect them from the criminal element (whos ranks will surely swell)? The Police??? Yea, right.
People are being pushed to the brink, the economy is not great for many, food costs are high, housing costs are high, unemployement has run out for many ... the news can spin it 10 ways but sideways but the truth is the economy is hurting people and their mental states can do little more than suffer. This country needs to focus on its priorities... let other countries deal with their affairs.. focus a lot of that money that goes outside on INSIDE causes like better mental services which for the poor is non-existent...unless you commit a crime..
Then why has these kinds of things been happening since the dawn of time? Starting with rocks, then spears, knives, swords and now guns. Someday it'll still be happening with laser guns. This has nothing to do with people being pushed to the brink. There are messed up people out there that do this. People kill people. The economy nor guns kill people.
an inordinate amount of random shootings right before election time...
Yea just when Obama is trying to get the UN treaty on arms control passed in the Senate to allow the UN to dictate to US that we have to gut the 2nd Amendment and allow UN troops on our soil to help carry it out!
Small economic depression + unemployed people with no future + inadequate mental health services + wide accessibility of guns + media elevating serial killers to the level of celebrity = a widespread Charlie Foxtrot
Um, the Batman killer in Colorado was hardly what I would call a bum. This runs deeper than the economy.
