[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.

When will you people realize that the second amendment has nothing to do with gun ownership.
So what does it have to do with? Do tell, your explanation will fascinate the rest of us.
legal guns has nothing to do with that. to all you morons screaming "ban all guns", it will give crooks more power. are you stupid? are you really beleive police will come and put their lifes before yours? just a bunch of stupid Bloomy supporters.
Gun control is just another "political football" that is tossed around in an election year.
Private ownership of guns is a good thing. If you ban the ownership of guns the criminals will still be able to get them. Another positive thing about gun ownership is that we will never be attacked on our own soil and if we are then we will have a means to defend ourselves. Private hunters and gun owners just in the USA make up the largest fighting force in the world.
9/11 wasn't an attack on our soil?
Guns don't kill people. People kill people. NYC already has some of the most stringent gun laws in the country.
Yes N.Y. has stringent gun laws but the guns used to commit crimes are coming from states like VA.
It doesn't matter if the gun came from VA or Zimbabwe. It is illegal to carry a gun in NYC. So the point stands. Gun control laws are useless when it comes to criminals such as this guy.
God bless the NRA...I am a life long member and support them 100% They fight for MY rights to be armed. Hey if these 5 people were armed this outcome would have been much different. Same in Colorado, Sweden, etc....arm everyone!
I doubt the outcome would have been different because it sounds like it happened fast and it sounds like the gunman was killed anyhow. Nevertheless, citizens rights should not be limited due to the actions of criminals and crazy people.
I believe that most law abiding citizens should have a right to own a gun. The only dilemma I have is when bring up past events like the Colorado movie theater shooting, Sweden, etc... Is that if we were all armed & a shooting occurred in a public gathering the confusion & the sight of every person pulling out their guns to confront the shooter, the collateral damage from everybody shooting would cause total chaos & possibly more people would get hurt. Also, it would be hard to identify who are the bad guys & who are the good guys until the all the smoke is cleared, so to speak.
interesting how ALL of the cities/municipalities that have GUN control & bans have the HIGHEST CRIME RATES IN THE NATION. That alone says it all – responsible gun owners are not more dangerous then responsible soda drinkers, except in NYC.
I used to think that gun control was the answer. It seems to make common sense. More gun control, means less guns, means harder access to guns, means less gun crime. It seems so simple at first, but it might be a lot more complicated than this and the scientific data has not borne this simplistic thinking out. Its hard to justify restricting the rights of the general population because of the actions of criminals and crazy people.
Ban alll guns forget being able to protect ourselves or families. Yeah yeah lets blame obama for some idiots moron decision whose prolly a mental patient. how about we blame the person who did the crime and not eveyone in governent. Goverment dont put guns in peoples hands people do.
Banning guns is not the answer. Creating stricter rules for those you sell them and imposing stronger penalties for those you have and sell them illegally, might be a good start. The sad reality isâ€¦firearms and hate will always exist.
New York City already has some of the strictest gun laws out there. Those did not stop the shooting.
Ban Guns? Let's ban cars too while we are at it. Cars kill more people everyday than all guns combined. Damn communist.
Dont ban guns. Ban people. A gun on a table by itself cant hurt anyone.
if people would be able to carry guns in NYC, only gunmen would be dead......
This will no doubt raise the temperature of all the gun-toting 2nd Amendment rights activists, but you're "guns for all" rights were written a looooong time ago for a country with a couple of hundred million LESS people. At the time the government was not very strong, and the only reason they gave you the right to bear arms was to appease the masses, so they wouldn't rise up against the new democracy. Now, it's just ridiculous. They WILL come for your guns. The south WILL fall again.
Not for anything, those that call for MORE GUN LAWS seem to ignore that criminals tend to IGNORE laws. Imagine if everyone had guns (licensed/training) they guy would have been SHOT quickly and probably taken LESS lives.
No....lets make more laws for criminals that don't follow them to begin with so only the law-abiding citizens don't have guns. Makes perfect sense in a looney liberal's mind.
Yeah because I would love to carry a gun everyday like I carry a cell phone. Give me a break, it's not the wild west. Let's say someone comes upon a shooting where you they see you take down a crazy gunman. Since everyone is allowed to carry a gun, what's going to to stop anyone from shooting you thinking that you're the one who's on a murder rampage?
