[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.

The shooter needed a job plain and simple give us our jobs back so we can eat
Must be a slow news day. Don't any of you people work?
if those 11 people had guns, that would not have happened.
Brilliant steve, another deep thinker courtesy of the NRA.
Too bad you have brain damage, huh.
I certainly hope thats sarcasm i'm detecting.
y don't u think the other way? what if this shooter didn't have access to a gun? ban guns in america!!! we the Americans are heading to another kind of war internally! this needs to be stopped asap!!!!
If that one man did not have a gun, this would not have happened
No, there probably would have been 11 times as many casualties. Trained police officers may have caused some of the casualties. Wannabe Dirty Harry's would have caused carnage.
If that one man didn't have a gun this wouldn't have happened.
If 11 people would've had guns there would've been 50 shot!

That is all...
New York needs to get over itself. This happened in your little area. Look to the west and you'll see a whole country who wasn't touched by this AT ALL.. tHERE ISN'T ANYTHING MORE YOU KNOW ABOUT THIS NOW. BE REPORTERS. YOU'VE GIVEN US THE FACTS AS YOU KNOW THEM NOW. Until you have more information – MOVE ON
If he had a job this might not have happened
bull, if he had a bigger toy he could have done a better job. Gee, if i could buy one of your toys here in canada, maybe i could come down there for target practice. You live by the sword you gonna die by it. You people will never get the message. Lol.
Wow, yet ANOTHER random shooting of innocent people.
Isn't it the NRA argument that "guns don't kill people, people kill people"? Well, that's true, BUT what is the argument then .. that we should ignore the fact that guns are the most lethal, easy-to-access ways for people to kill us? There are lots of crazies that can't be counted on to be responsible citizens. LOTS ... and recent news proves perhaps even more than we thought! We have everyone from babies to congresswomen being shot and killed in random, meaningless shooting sprees. What, do we do nothing because it's "people" that kill people?
Take away a crazy person's gun and they can't shoot you anymore. It's alot harder to kill people with knives and bombs than with hidden guns. Alot harder. Expand background checks. Make it much harder to get a gun. Ban assault weapons like machine guns. Pay for more police so citizens don't feel they NEED to protect themselves.
We have to do something here, people. What kind of country is this? What good is it to be "free" when you or your baby or your congresswoman can be gunned down any week by some crazy kid or disgruntled worker that you have never met in your life? Come on! Let's react! Let's do something!!
Here here !
I agree. This country is going to "demand it's rights" into an early grave.
That's right, John. Start jumping on the "ban guns" bandwagon before knowing any facts at all about this incident. We don't know where the shooter got the gun, how long he's had it, etc. yet. Why don't you get off the soapbox until you at least know whether this incident supports your argument?
Very well stated John.
Nice rant. But NYC has the toughest gun laws in the country other than Washington D.C. and yet this shooting still happened.
This is living proof that gun control doesn't work. Haha
What is it I need to know? This crazy person got a gun he shouldn't have gotten .. and killed innocent people with it. Just like all the other recent crazies who have been killing innocent people left and right across the country.
These have not been organized crime, mafia, or militia attacks .. they are random, individualized attacks. If guns were banned, we would only have to worry about militias, mafia, and terrorists .. instead of every moody, violent, or mentally ill crazy on the street, too.
NY has some of the toughest gun control laws in the USA. Gun crime is rampant.
Switzerland forces ALL men to keep a government supplied firearm in their home. Switzerland has the lowest crime rate in the world. It seems an armed populas is a polite populas. A disarmed populas is at the complete mercy of armed criminals.
What say ye?
What, more gun control? NYC already has the toughest system of gun control laws anywhere and they clearly failed(again!). Yor arguement that a person couldn't have done this without a gun is flat out wrong. There was an incident here in CA recently where a man attacked 11 people and killed 3 of them and seriously wounded the rest... with a KNIFE!
All gun control does is create defenseless people, i.e., TARGETS.
Sounds like more gun control is needed (by the police). Eight people shot in cross fire and they are not sure the perp even fired a shot at the police.
Should they have waited until they were actually shot by the gunman before they returned fire?
Well, NY State has a no gun law. The only people with guns in New York are cops and criminals. So, whose fault is it? You can't cry, "See, this is why we need more gun control". This senseless crime happened in a "no guns allowed state". It's too late! There are too many guns out there. There will never be a total gun control in this country. If it were to happen, the only way the recover all guns is crime by crime and those willing to give up their guns. This could take a few life times to achieve.
And yet the man had a gun. Since many states do have very lax gun control laws it would not be hard for him to buy a gun and drive back to NYC.
Too true. Criminals don't obey laws now! Why do these Sheeple keep thinking more laws will reign in the bad guys! Idiocy!!! And NY state has no ban on guns. But in NYC there is a city wide ban on guns of any kind. So to all you Sheeple out there remember criminals will always have guns. Are you ready for a society that leaves you the law abiding citizen open for victimization by thugs. If you think you can sleep soundly at night, as for me MOLON LABE!!!!
Over half the victims were shot by NY Cops in a crossfire. WTH? These idiots couldn't hit a barn.
Cops shot innocent citizens...about average for LE in this country.
See folks! LEO is not your friend, they are as power mad as any other lunatic
NO GUN CONTROL. NO NEW WORLD 0RDER.
Obviously this story is fake. Guns are banned in NY.
Everyone is overlooking the real reason he had no job no job means no food nothing to look forward to
He did have a job, maybe he was fired because he's a nutjob.
