[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.

i am so enarged by this!!! another shooting..thank god police reacted quickly as they could..pray there are no serious fatallys
Keep your ammo dry pilgrims!
This is the problem with the direction we are headed. Texting and cell phone calls while driving kill more people every year than school, theater and mall shootings. So, what next, are we gonna ban cell phones now. We have laws in place to regulate it and to show people there will be consequences to these actions but do you think it's gonna stop everyone from texting. This is awful what's happened today and so many of the people you are blaming here, spend their time and money promoting and educating others about gun safety.
I am a gun owner and you know what I am VERY SCARED OF and would like banned? SUV's! Especially people driving them at 30mph over the speed limit on city streets while talking on the cell.
Be afraid of SUVs. Be VERY AFRAID. I am willing to have my guns be banned if SUVs are banned also. They kill more people than guns do. How many of you anti-gun folks drive an SUV? Or a "show" truck (decorated pickup truck)?
so there are laws banning drugs and based on theories here that should translate into no one possessing them, right? sports ban steroids and you cannot buy them so problem solved, right? everyone needs to really look at the problem and banning guns is a band-aid not the solution. the solution is the erosion of personal values, family units, etc. If I am a kid growing up today, what do I learn? hate the rich and expect more for doing less. ban things that are bad, expect for drugs such as marijuana which we should legalize... I think people are losing there mind and need to step back and really think about it
For those bringing up the Norway shooting...just some facts for you all: Norway averages 10 gun homicides per year compared to around 12,000 in US. The 84 killings in Norway is equal to about 1 day of shootings in US. So, that is really a poor example for you to use. More importantly, we should be concerned about these poor people and start working together to find a way to stop these mass shootings.
One way to stop mass shootings like this is to read the article and note that the perp only shot ONE person and the cops – through grotesque incompetence, killed not only the perp but nine other people. Maybe disarming the police would help stop situations like this.
Another poor example would be to compare a country that has a white population in the 98% range to a country with a vast minority population. Hey! Maybe THAT is the reason why they have less crime!
But then that would be politically incorrect to mention wouldn't it?
I am glad In NYC it is illegal to carry a gun, without out the law this would have occurred.
One less lunatic adding his boiled urine to the gutters. At least ten less people to deal with during rush hour tonight. Win win!
How ironic would it be if the gun used was from Fast and Furious...
Sooooo sad!! People are literally losing their minds!! Log on to http://spilldabeanz.com/ for the Latest in Crimes, Fashion and Celebrity Entertainment!!!
your shameless advertisment is also sad. If you sincerely want to leave a comment on this article, dont add your advertisment at the end. It makes you seem insincere
I am quit certain that this is what the first amendment was for, end sarcasm. It's time for the NRA to be sued for something creative. Like depraved indifference. Someting, anything. Too many guns!
Umm, the first amendment is only for shooting off your mouth.
I agree.
I agree with Watcher comment.
It’s the second amendment you moron.
If everyone had a gun, this guy would have been dead after his first shot... and you need to learn how to spell.
2nd amendment. Get a copy of the Bill of Rights. My money is betting that it was some religious nut concerned about his 1st amendment rights. Don't forget, all of these shooting occur "In Jesus' name, amen."
I was in the middle of this just now. It was horrible !!!! and I still would not agree with you.
We know government is full of virtue so only government should have guns.
It's ignorant treasonous cretins like you that make life Hell for ultra-law-abiding gun-owners like me. Guns are inanimate objects and had nothing to do with this crime. It was a defective person that did this – and stupid cops who lit up a crowd when they should never have fired back.
Ignorant, stupid, unaware, moron, surely there are other words to describe this cretin!
Obama's America.
What a fool!
The NRAs America
Maybe U2 can put on a concert to create another smokescreen
Why does this story have terrible sentence structure and grammar. I have noticed at least three major mistakes and it is only a short update. CNN you really need to hire people who know how to proof read, this does not look professional at all.
Yes, we need gun laws like Switzerland which has no standing army and relies solely on a militia. Every male of military age is required to be trained on and possess a fully automatic weapon in the home with at least 100 rounds of ammunition. Why don't these things happen there?
They do....
You want the Swiss rules? Currently the militia do NOT keep ammunition in the home, except for a few rapid response soldiers. Ammo sold at ranges must be used there. They are subject to inspection of ammo in the home....
Also, note that each person is a well trained soldier, not random untrained redneck yahoos.
Notice that they have a "well-regulated militia"? Maybe we too should restrict gun ownership to members of a well-regulated militia.
Still want the Swiss system?
Oh, yes, just another day in the neighborhood for the White people to kill.
Terrorist?
Nope – disgruntled flamer.
