[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 Empire State Building is one of the most famous skyscrapers in the world, and one of New York City's best-known tourist attractions.
Each year, about 4 million people visit the building's two observation decks. At more than 1,453 feet tall, the landmark building reaches more than a quarter-mile into the sky.
Your right. Once again, because of the strict gun laws, more people were injured than needed to be.
Soooooooooooooooo let me get this straight.
New York has some of the strictest gun laws in the country designed to keep guns out of criminals' hands but the only thing the laws succeeded in doing was to keep guns away from law abiding citizens, thus preventing said citizens from protecting themselves?
And the REASON New York has such laws is becuase it believes only trained professionals from the government are capable of handling a gun BUUUUUUUUUUUUUUUUUUUUT those very same professionals shot 9 innocent people (according to CNN).
Sooooooo NYC locks up an out of state, former member of the Armed Services for declaring her gun at a check point, but the guy in the Empire State Building just waltzed in and started firing.
New York. I weep for your loss today. But I also shake my head at your incredible stupidity.
Yeah, professionals may have shot some of those 9 that were injured. Imagine what would happen if non-professionals were carrying and decided to cowboy up. The idea that a civilian carrying a gun would have ended this or Aurora or any other shooting event in a safer manner is the illogical propaganda of gun nuts. I'm all for protecting the 2nd Ammendment but guns don't make us safer. They just don't. For every grandma who runs off an attacker b/c she was packing a Saturday night special, a young kid blows his face off b/c he was playing with his father's gun.
This story is obviously a hoax. A shooting like that couldn't happen in NYC, they have the strongest gun control laws in the country.
Hahaha, gun laws only make it easier for a criminal to kill more people as no citizens have the right to protect themselves and the only people with guns are the ones breaking the law. You might want to rethink your logic bro.
I am sorry to hear about this tragedy but isn't this Bloomberg's perfect gun free Utopian city. How are those gun free zones working for for you New Yorkers. Here in Kentucky we don't have near that kind of problem but, then again, we don't have near the Liberal Gay Democrat population either.
Same thing in Vermont. And I wouldn't call the state with Sanders as a Senator a bastion of conservatism. They can even open carry, without a permit!
Read a little history. Governments with guns have killed more of their own citizens than citizens killing citizens. Ask the millions of dead Russians and Jews if Stalin and Hitler banning guns to prevent violent crime was a good idea.
Police and CITIZENS (not "civilians"). Unless every police officer is in the US Army, non-police person is a citizen, not a civilian. And every police person likewise is a civilian when in comparison to US Army personnel.
If its know that more and more citizens are carrying guns, less people will try something stupid and more people will be armed to prevent that kind of situation. These reports of shootings seem to be more propaganda to convince Americans to give up their right to bear arms for a "safer" world. Let me just say this: Criminals don't follow rules and if something is illegal, it just means that the only people who have it are criminals. Lets stand together on the right to bear arms for the real safety of American citizens.
13 shot in Chi-town for the lead, but New York's finest in Blue makes a strong showing with only two minutes left on the clock! Eight wounded but the tally is still out to whether the donut terrors can claim them all.
Unbelievable. You can't carry a gun in NYC. We know every crook, crazy or anyone else intent on shooting people would never have access to a gun in NYC. Of course they will throw the liberal slant to it. "We need more gun control. We need to take guns from the people." Law abiding permit carriers could have been a big help here. People want to know why I don't want to visit NYC. This is the exact reason, I don't have my right to defend myself in case something like this happens.
What a dream world.
Cool story, bro. If everyone pulled out a gun after shots fired, people would know exactly who the bad person was. And you wouldn't be confused as a bad person, because you look too much like a good person. You're smart, you watch movies.
seems america is back to itself as it was before 911
Let's all get together and play GI Joe's and watch Die Hard and talk about how awesome it would be if we could all carry guns and we'll make plans on how we'll get the bad guy. It's going to be awesome.
Stop giving our taxes to Israel. We could use that money for jobs and housing right here in the US.
if everyome who lost their job in the past 3 yrs and 8 months and 3 days went on shooting spree it would be a major bloodbath for several million citizens,,,,,
When apple pie is outlawed only outlaws will have apple pie.
Cool story, bro.
Of course,Obama,Hillary and the rest of the anti gun club will jump all over this in the attempt to use it for more leverage to ban guns and destroy the 2nd amendment.
Banning guns will solve nothing and cause MORE people to be victims because the only ones left with gns will be the government and criminals.(Both 1 and the same).
So....I guess if it's crime you're seeking to commit,find out what towns and cities have strict anti gun laws and gun bans and go there to commit the crimes. You'll be shooting fish packed into a barrel with no defenses.
Yeah, because cops are more spupider there. And all cops shoot elusively and all good citizens shoot perfectly. This has been proven in all Die Hard and Lethal Weapon movies. Thanks for being a good guy and thinking good guy things.
