[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.

If only there were a few citizens packing heat.
This kat would have been taken out quicker.
Yes, because the trained police were so accurate with their shots, I'm sure an old lady packing a 9 in her purse would have helped the situation.
The bad persons eye patch should have given him away at the start. Because all bad people wear eye patches, right? I'm pretty sure he was wearing a metal glove and holding a cat. It was so obvious. If only a brave citizen would have shot him at the start, no one would have been hurt.
we really need to take a look at how we raise our children in this country â€“ helping them to understand the value of transparency in dealing with their stress, anxieties and emotions as well as anger and rage. my three-year-old gets very angry and doesn't quite know how to express it, so she gets very worked up and lets everyone know about it. she doesn't know any better. but that type of behavior seems to be showing up more and more in adults in stories just like this one. something isn't right, and in an effort to vent, they take it out on innocent and unsuspecting people that surround them. deeply saddened every time i read a story like this. it should be preventable.
Well thanks to the cops, the city better get ready to grab it's cheeks and open wide. The lawyers are no doubt already jumping into their batmobiles.
So Bloomberg will now ban people from working in buildings, ban employers from firing people, and will ban the police from killing suspects who draw a weapon on them. After all, personal behavior and personal responsibility for its results were banned a long time ago in New York.
Wow! I sure am glad we have a lot of guns here in this country!
The unstable are everywhere, you just don't know where. There is no way to track them.
The article says that the gunman "ran after and shot a man in the head"; that two were killed including the gunman; that a woman was killed as well. So which is it? Two or three dead? "including the gunman" means he is dead and the person he shot in the head is dead. Or was it a woman he shot? Or is that part of the article rumor reported as fact in all the confusion I'm sure abounded at the scene. If most of the people injured were hit by bullets from NYPD guns then they need some serious marksmanship training.
How about manufacturing of guns only to police and the military. Long guns for hunting is NOT the problem, it's these damn handguns and assault weapons that have only one purpose....to kill other people.
Oh great so the gunman killed one person and the police shot 8 accidentally, what a great way to protect the public!!!
Ok let's hear it from Bloomberg, "We need more gun control". Typical brainless liberal reaction. Tell you what, Bloomy Baby, if you hadn't already disarmed your law abiding citizens, this guy may have been taken down by a couple of them before anyone else was hurt. I know, that's a concept you just can't grasp.
Thats the answer! Arm all of nyc! Brilliant!
This story was reported terribly wrong here. It started as "gunman opens fire on crowd" and now we see there are only two dead. The gunman shot his intended target, then the police shot him. There would have been no other shots fired or bystanders hit if the police didn't open fire on him. It's a murder, plain and simple, not another mass shooting. Wouldn't have gotten near the attention if it were a stabbing instead of a shooting, although the result would be the same. This happens everyday (sadly). C'mon CNN, stop feeding the gun control civil war that's brewing.
Not to mention that the 9 people were likely hit by POLICE fire...
This shows how INCREDIBLY IMPORTANT it is to HIT THE GROUND when you hear gunshots.
On a New York street? Better to take your chances...
Looking more and more like the Police shot most of the victims. Surprise, surprise...
Of course you know they enjoyed that.
So the gunman shot one former worker in the head, and it is not clear whether he fired any more shots at the police, but 9 were wounded ibn the "crossfire"? I hope this is not true. Please tel me te cops didn't shoot up all the civilians standing around while trying to take down this nut with a long gun.
Damn, what's with all these white guys shooting everyone up. As a white guy, I hope they don't start profiling me.
