the mayhem and bloodshed outside of one of the most famous landmarks in the world, the empire state building. Breaking overnight, dramatic new video of the gunman just released to the public. And ron is here with more. It was a wild, and for many people, frightening scene. Witnesses said it was something like out of a movie. This was very real. An armed man, gunning down a former co-worker and being confronted by police on a crowded manhattan street. When it was all over, the gunman was also dead. And nine innocent bystanders, they were wounded. This dramatic new video, shows the gunman, jeffrey johnson, walking up the street, just minutes after allegedly killing his co-worker. Two police officers approach him. He turns. And police say he appears to try to fire his gun. But it jammed. A split-second later, police open fire, killing johnson. Officials say the hail of police gunfire very likely wounded all nine bystanders. I just got shot. Reporter: One of them, robert asica. The bullet went in and came out my right arm. I'm very, very lucky. Reporter: Witnesses describe a scene of chaos. With hundreds of bystanders stampeding through the streets to escape. The wounded laid out as if it were a battlefield. I heard six or seven gunshots. Very crisp. Very loud. Reporter: Rapid succession? It began friday morning. The shooter walked toward fifth avenue, followed by a construction worker that witnessed the shooting. That worker alerted two police officers on duty outside of the empire state building. Then, near the tourist location, that blooding shooting. After the shooting, police said the gunman came up here, with his weapon put away, stashed in a black bag. At that point, a construction worker pointed him out to officers. Police officers fired at the gunman. Police say some and possibly all of the nine bystanders hit by police bullets or flying shards from some planters that were struck. The way I was standing, there's no way it would have been the guy that hit the people that got hit. Reporter: None of them sustained life-threatening injuries. And police say that johnson bought the gun he used, a .45 caliber semiautomatic, legally, 25 years ago in florida. Investigators believe his motive for killing his co-worker, a bitter personal dispute between the two. Not because johnson had been laid off from his job as a fashion designer a year ago. And neighbors described him as quiet. He dressed every day as a suit. This day, as usual, wore a suit. Went back to his workplace and allegedly killed his co-worker. Ron, thank you.
