[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 casualty of Obama-nation.
And just how is this connected to Obama? Even better how is this connected to anyone other than the individuals involved at this point?
Learn english first. What we are dealing with nowadays is definitly a porduct of human right abuse. You fire somone without even thinking twice and that peson probably has a family to take care of. What can Mr. Obama do? He is trying his best but the corporate power is there trying to; and screwing everyone.
Obama is not a "looser" Clinton was "looser" with Monica, but Obama is faithful to Michelle. Please learn English "mo betta" before posting on here, whether you really are a Chinese student or not. Also, below you wrote "Obama is a socialism." This makes no sense. People of your intelligence will vote for the GOP, here's to hoping the majority of the USA is better educated than you.
Guns should be Legal to carry so people like these will think twice before they start a shooting spree.
a Mad person will find gun one way or the other, its the Good citizens that want to protect their families from these Nut people. Gun is simply a tool, Banning Gun will not solve problem, a killer will kill any way by using any other tool such Nail Gun, home made explosives, Matches, keroseen oils Hammer, stone etc etc etc so what now you gonna Ban the stones, hammer, Nail gun too.
another White Terrorist
Exactly, Joe. A madman doesn't care about cops caring guns, he's concerned about citizens caring guns. All crazy, delusional people asses only when citizens carry guns. And it was so obvious, when a guy with an eye patch, metal hand, and petting a cat is walking around, he must be the bad guy. 'Cause all bad people look the part, right? And when 10 people with guns pull out there gun, when they hear gun fire, they are automatically able to distinguish the bad guy.
That is a known FACT. And it was proven time after time on Die Hard I, II, and III. Not to mention all Lethal Weapon movies.
Did you even read the story? he targeted one person, killed them, ran away and was shot by police. the other victims were injured by police.... how would a conceal carry permit holder (which is possible in NY) have helped at all? The police need more practice on using their weapons.
NYPD Is a joke!!!
Has the question been asked whether he was receiving unemployment benefits? If the he was denied continued benefits could this have prompted the shooting?
Reminder Readers. Twenty-three( 23 )states do not disclose information on their citizens to the "background check" system. Back ground checks are only as good and accurate as those who help provide information. While we are continue to be told how good the back ground checking system is.
The background check is especially effective with criminals....not!
it is to bad that anti gun mayor bloomberg has police that can't practice enough to shoot straight and end up doing more harm than the gunman,gunman 1 police 2 plus many wounded.it is terrible anyone was killed or hurt but for the police to be so bad and for the mayor to offer his usual tripe is also terrible.he should move to israel and join the defense force to learn some reality, versus his believe that really rich can say anything.
Does the policie have to kill ..... And hurt innocent people who was just walking by, non lethal weapons ...
Of course this shooting was terrorism. It will frighten people away from visiting the Empire State Building, or maybe even New York City. A terrorist doesn't just kill his victims–he inflicts harm on strangers he's never met too.
Terrible reporting as usual. "The victim was Johnson's former coworker at a was a "disgruntled former employee" who shot a former" a former what?? There isn't even a period to end the sentence? I wonder how many innocent bystanders the police shot. NYPD has a terrible track record in this area. We saw video just the week of a NYPD officer discharging this weapon into concrete at a short range from bystanders.
I watched the story unfold on television as I had just awakened here on the West Coast. By the time the mayor of New York started speaking, the story had changed completely. I think the media will say anything just to get their story out first. Remember when the dead person was a young innocent bystander? A female? And on and on with poor info. Maybe it is best to wait an hour before watching the coverage to get to the truth.
Who in the hell thought that a shotgun was used for the news to report that?
Was it the news sensationalizing or do people of NY just not know the difference between a shotgun and a handgun?
Did this unstable moron have a registered handgun or a "Saturday night special?" I, and everyone else, have the right to defend themselves. If there is no desire to ban illegal handguns then you must allow legal weapons. These mass shootings make headlines, but in South Florida that is a concealed carry state, everyone just looks the other way when unregistered handguns are used, usually in African-American communities where illegal guns are paramount. That doesn't make the people they were used on any less dead. The drive-bys that kill innocent children who are doing nothing wrong is what needs to be addressed. Not registered handgun owners. There are nuts everywhere of assorted varieties but unregistered handguns are an epidemic, but no one is addressing that. In New York City and other cities they are just going after registered gun owners and letting the criminals have a free pass. I guess in the grand scheme of things. super size sodas and salt are much more lethal than unregistered guns, especially from a politically correct nut job on his third term without the cajones to address the real and serious problems and risk being called a racist.
I wonder if police should just pursue and call back-up before they start shooting? I have heard one too many stories of innocent people getting caught in the crossfire or in fatal car accidents. I am not sure it is a good judgement call on their part to put other people at risk in that way. If we want to have less "crazy people" with guns (even though I do think they could be better regulated, even in a state that has such strict gun laws), we probably should take better care of our mentally ill.
Good the police did their job not taking him into custody; this saved lots of taxpayers the bs of continual news coverage of a needless trial by jury.
But the police shot innocent people while shooting at the gunman.
We need to start profiling White American males..wait that won't happen they aren't brown.
Like two years ago, in downtown Orlando, also an ex employee was the shooter, and I believe he was PR. So crazy people comes in all ethnics and skin colors. Stop the racism.
