According to witnesses, Johnson's approached Steven Ercolino - the account executive at the company that fired Johnson last year - without saying a word.
He proceeded to pump numerous bullets into him, even standing over Ercolino's body and continuing to shoot after it was clear the victim was dead.
"Steven was a wonderful son. He was very good son and person," Frank Ercolino of Warwick, N.Y., told ABC News.
After taking Ercolino's life, Johnson walked away and was followed by a construction worked who warned two NYPD officers. They confronted Johnson, who pulled out his gun, held it up - and was shot dead by the two officers, both of whom were standing approximately eight feet away.
