Here is a full recount of the Empire State Building shooting as we know thus far:
Jeffrey Johnson, a 56-year-old former employee (previously reported as 53) of Hazan Imports was laid off about a year ago.
Disgruntled and still upset, he came back a year after losing his job with the apparent intention of shooting a specific co-worker.
New York Police Commissioner Ray Kelly says Johnson successfully shot his co-worker in the head three times outside of the Empire State Building before fleeing the scene.
A construction worker spotted the suspect fleeing and alerted two uniformed police officers nearby who began to tail Johnson.
The suspect then turned and pulled a .45 caliber pistol on the two approaching police officers, who then opened fire on him.
Nine people were wounded or grazed by gunfire in the crossfire. The mayor and commissioner both said the wounded were possibly caught in the police officers' crossfires.
According to reports, the handgun the gunman had could only hold 8 bullets.
