[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.

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.
Sad to hear this. Seem more and more crazy people out there now days running amok killing others or killing them self like no body business. Wasted human life.
To a believer you know life and death is in God hand. Prayers wont stop you still from dying but you know your soul is with god and rest in peace.
To the unbeliever,you walk on god earth like you own it ,you still will die but your soul be wondering eternally.
Still argue about this than just sit back and think hard about life and death. Unfortunately for some, busy glittering material world have blind many to stop and think what wrong have they done to their soul, until death come.
Prayers to the lost soul.
Human creation is not what killed but what human used it to killed and how.
Seems like the breakdown of the family and devaluing of men as fathers and husbands by women is causing a lot of problems. The old days were way better.
@Kurt – Yes, the conservatives answer to everything, keep the women barefoot and pregnant. And lower taxes. Charge full speed into the 19th century.
Kurt, so there was no violence like the KKK or the Holocaust back when women were homemakers?
What if in the end we find out that the co-worker was the only one shot by the man, and everyone else was shot by the police? This is exactly the reason no conceal carry holder (many were present at Gifford's shooting) did not open fire! There are people in the way!!!!!!
I was visiting the empire state building only last week. There were lot of tourists..What a shame
This isn't a story so much about 2nd amendment rights but about treating people with respect. We learn so many valuable lessons in early childhood about socialization about treating people the way we want ourselves to be treated. Unfortunately, this person could have done the same amount of carnage with a bomb, acid, knives, what have you. As a society, we really need to reach out and help those that are in need rather than assume its best if everyone fends for themselves. If we don't show compassion for others, we will be taught that other golden lesson: karma.
I agree! I don't think kids here are taught enough of that in school these days.
Boy, those pro-gun cowboys in New York are really scary.....snicker
9 times out of 10 the ppl the black ppl shot they knew them.. 9 times out of 10 the ppl the white person shot he didn't know them at all.. he just had a bad day and decided he was gone kill 10 innocent ppl!!!
Some people may have been accidentally shot by police officers. So now the anti-gun nuts are going to say we should take away cops' guns too, right?
No. It shows that even trained police officers cannot shoot without killing friendlies. And most gun-owners do not have a clue and are pretty bad at shooting – just shows that having more guns on streets will only harm more people, not protect them.
..Crazy Americans, white, black, yellow – except native Americas, all the rest are just bunch of Crazy citizens as hell !!!
Why not native Americans? Because no one used a bow and arrow?
***Insert pointless Gun Control comment here***
don't you love Bloomberg last stament theres a lot of guns out there.
Some people may have been accidentally shot by police officers. So now the anti-gun nuts are going to say we should take away cops' guns too, I guess.
*Some* people? No, 90% of the victims were shot by the cops.
You are a sick little kid and one of the primary reasons this world is so damaged.
Once again, CNN gets it wrong. Hazan Imports was not inside the Empire Statue Building, it was on W 33rd. The Empire State Building played no role in the shooting other than its being nearby.
Not surprised by the bad reporting.
Who done it this time?
Another false flag so a gun grabbing ban is passed
Is a merican what do you expect? We all go buy gun and shoot, and kill. Are you mad? go to gun store and get one, just like buy a gallon of milk
That's not true. Handguns are illegal in New York City, they HAVE gun control. See how well it works?
RandyMarshCT: Who says the gun was purchased in New York? It could have been LEGALLY purchased in a nearby jurisdiction. It's not like its hard to do. Keep holding your empty bag, teabagger, and rationalizing this insanity.
