[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.

Another shining example of our need for gun control. Seriously, when will everyone wake up and realize that our right to bear arms doesn't mean everyone should be able to get them. Some people are just too unstable and/or stupid to be trusted with a gun...
very sad
So Bloomberg- how's that gun/ rights/ illegal search thing goin for ya? National Socialist clown
PEOPLE CONTROL - NOT GUN CONTROL As a police officer, I do not believe I would have confronted an armed suspect, already known to have shot someone, but displaying no weapon on a crowded New York street. What were they thinking? Just follow the perp to a more safe condition and then confront him. If the perp wanted to harm no-involved citizen, he would have a the primary crime scene.
Guns are banned in NYC...so why is there gun violence? Funny how you never hear about gun violence at a Gun Show or at a shooting range? Maybe because others are armed?? 20,000 gun laws on the books.
An armed society is a polite society. Manners are good when one may have to back up his acts with his life. – Robert A. Heinlein
So here's the thing.... highly trained NYPD officers accidentally shot and wounded innocent bystanders while attempting to subdue the shooter. I guarantee those officers are better trained than the local cops in my home town, and they are DEFINITELY more capable than the average gun-show attendee. The last thing that I want to see is someone who has watched too many Clint Eastwood movies pulling a gun on my crowded subway thinking that he's going to save the day and then accidentally shoot my daughter.
I don't hear about all the automotive accidents happening on our highways everyday, that must mean they don't happen, right?
Detroit has 4 times the population of its next door neighbor Windsor in Canada.They both have had severe unemployment problems.During the period Sept.27,2009 and Sept.27,2011-there were no murders in Windsor and 260 in Detroit.Difference gun control.– Chaz
Haha...there are q good bit more differences between those two cities than just the gun laws in their respective countries.
So residents of WIndsor want to shoot people, they just can't access guns? Doubt it.
Windsor, Ontario is 77% white. Detroit is 82% black. Are you actually foolish enough to believe that the only difference between the two cities' murder rate is gun control?
We need leaders at this time. a mass killing happening every week or so in our country right now. yet, all out supposed leaders-obama and romney- do is issue these isipid, useless statements about what a terrible thing this is. we already know that. A leader is a person who stands up and does the right thing regardless of the consequences. we need some version of gun control and a national conversation about what is wrong with our society. Obama and Romney are not leaders. They do what need to do and say to hold onto or grab power. No courage. Not men who should hold power.
Jim, this is a reply to Adam’s comment. I can’t reply to his comment directly as there is no reply button for reply comments.
Reply to Adam:
Adam your comment is pure stupidity. The man who shot up the movie theatre is black or white? This is not a black or white thing. There should be better gun control laws in this country.
Deni, clearly you have reading comprehension issues. My comment was to Jim's statement that reads as follows:
"Detroit has 4 times the population of its next door neighbor Windsor in Canada.They both have had severe unemployment problems.During the period Sept.27,2009 and Sept.27,2011-there were no murders in Windsor and 260 in Detroit.Difference gun control."
To make the statement that the difference between 260 murders in Detroit vs 0 murders in Windsor is solely linked to gun control is pure fantasy when you consider the population makeup of the two cities. Does it make an impact? Possibly. Is it the only factor? Of course not.
More "crowd" control by the NYPD. Shooting innocent bystanders. A lot of them are roided up thugs now, trained by Israel and the Department of Homeland "Security".
Really? This man didn't kill his coworker because of the recession, if indeed the recession was still upon us. Further, recall the economic collapse happened during the Bush administration. Bush's two unfunded wars (every war in the past was accompanied by tax increases to pay for them, which real patriots, including wealthy ones, paid without any whining), Bush's tax cuts, most of which went to the top 1%...yeah, this is Obama's fault. Oh, let's not forget a Republican coalition in both houses of Congress who have blocked every single attempt this Administration has made that would help fix the problem. The last thing they would want is for this black president to have a record of success. Which he has.
So. . . How's that gun ban working for ya NY?
New Yuck? Well, aren't you cute with your worthless comment. You can now go back to watching Jerry Springer.
Insanity.
i think if he had a job this would not have happened something has to be done or this might become more frequent
Mayor Bloomberg - Mexico has total gun control. Citizens are not allowed to have guns.
How do you think that is working out for them? Is this what you want for New York?
Considering that you are nothing but a redneck racist, I'm suprised you are calling for all-out race war.
Those that say that we don't need effective gun laws because "guns don't kill people" and "people will find other ways", are like saying we shouldn't have any traffic regulations or license tests because they don't prevent 100% percent of road rage/car accidents.
Key words in anti-gun posts = "effective firearm laws". The only effective (proven by statistical numbers) firearm laws passed in the last 40 years have been the ones allowing Concealed Carry by citizens, and the removal of the ban in DC.
The Concealed Carry law in Florida was so effective, Handgun Control Inc. had to compare Total Violent Crime numbers afterwards to Crime Involving Firearms numbers before the law in order to argue otherwise.
Face it, there are contries with complete bans on modern firearms, and they have crimes being commited with uzis. Enforcment is the problem, criminals get weapons illegally.
When seconds count, Police are just minutes away.
