[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.
Pictures from the scene
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.

I'll correct myself
Go Mitt/Paul! Go Romney/Ryan! ;)
The guy just wanted to take care of one particular a..., and to walk away peacefully after that. So – 9 others getting shot is the police's fault.
So let me get this straight. Guy shoots and kills one guy he (I assume) targeted because he was PO'd over job stuff.
He attempts to flee the scene and the pigs shoot NINE MORE BYSTANDERS trying to get him. Does anyone else see something inherently wrong here?
Try being a cop and see how easy it is. Have some respect.
So Mark, you were there and saw the POLICE OFFICERS shoot bystanders? Maybe you need to shut up. You and the other opinionated out of towners.
Right on Mark. Its obvious the NYPD doesn't understand gun safety and probably should be disarmed... especially the ones who surround hypocrite Bloomberg.
Sure, blame the NRA.........again!! Shootings always make headline news. Yesterday in Philadelphia, a mother beheaded her 2 year old child and then killed herself by sticking a knife in her own neck. No national headline news on that one.
What a lot of the pro gun lobby are missing is the EFFICIENCY with which a gun can kill. This is the reason they need to be controlled. You can't kill with anywhere near the same efficiency with other weapons.
Ah! So you don't object to violence, just to efficiency. Inefficient killers take note.
Tell the dozens of people killed and injured in each of the bomb and vehicular violence incidents the last few years that "guns are the most efficient way of killing", I would love to see their reaction.
"Johnson pulled a .45 caliber gun on the approaching police officers but it not clear if he actually shot any rounds as police opened fire on him, Kelly said"
Come on CNN take a minute to read before you post.
The shooter killed one individual. then fled. When later pointed out to police, he turned with gun in hand, and was shot by police. It is unknown if he fired on them first, or at all. What's your question?
I am so confused by this article! Makes no sense. I know less facts by reading it than I did before. A big red F on the top of this assignment.
THEY ARE REFFERING TO SHOTS FIRED AT POLICE
money it all comes down to money plain and simple no job = no money
so how's that police state/state-of-the-art-big-brother-national-securtiy-crime-prevention-tax-dollar-sucking-TrapWire-surveillance spy cam system working out for ya Bloomberg?
This comment deleted by CommieNN in 3...2...1
The man was killed at the scene. The system does not predict the future. Not sure what your point is.
What a SICK SICK SICK country we are! Ciizens don't need handguns or assault rifles. Only law enforcement should have guns.
This guy was law enforcement? Ya didn't think so
oh yeah, that will help. how many people died today in car crashes in NYC? Ban cars next because they take lives too...often times in accidents, not planned attacks like this.
You are free to choose to not arm yourself...and based on current reported facts certain police officers should choose that option too if its true that many of the victims were killed by the police. Horrible collateral damage from poor marksmanship. However, for the rest of us law-abiding citizens, we aren't going around killing people and are free to choose to arm ourselves for protection or any other legal use... This is just another stupid excuse to get anti-gun nuts up in arms...
When only the gov't is allowed to possess firearms then we have a totalitarian regime !!!! We don't want that at all !
It looks as though more people were shot by police than the "shooter". Poorly trained officers with too much firepower and very little training or a practiced armed citizen using one or two shots- how would the outcome have changed?
Let's see, a guy w a pistol in Bloomberg's people's republic. Want to bet it was illegal Malakia
You can't be serious.
Sounds like the cops killed 10 people?
ya, just lets just give it all to the government. They will take good care of us.. you Dolt. you don't deserve peace or security because you want to give up your freedom.
Just hang on to that Marxist ideal when I have to sit by idle as the phsyco takes the time to empty his entire magazine one round at a time into yourself and the other unarmed people in the crowded theatre, because it is a "no gun" zone.
NYPD is a joke! Not long ago a bunch of cops(pigs) unloaded their weapons on a guy who was holding a knife!
What kind of training are these pigs having? -Just a bunch "wanna be heroes" and "trigger happy" , untrained, uneducated fools!
NYPD is a joke!!!
tell that to those killed in 9/11
An investigation would be needed to know why 9 innocent people were shot by the police.
Sometimes that rings true. However, in this situation, they reacted properly. Easy to make assumptions if you are working with second hand facts. I myself am definitely not a fan of the NYPD because of your precise description of them. However, the scene this morning was nuts. A disgruntled jewelry designer who was fired a year ago, decides today to kill his co-worker? And his co-worker, not his boss? Not exactly sure how much sense that makes or how true it is but I know what I physically saw with my own eyes. This guy needed to be taken down and NYPD reacted responsibly and with caution.
What the hell is 'a socialism'? Stupid chink.
Wow, how many does that make so far this month? What's wrong with you guys over there in Americuh. Can't solve your problems without shooting someone? Keep it up guys, you're looking good.
Just what we need, another crazy with a gun.
One Chinese Student go back to your communist country and learn how to spell !!!
Christians killing Christianns like Islamists killing Islamists
