Pittsburgh Crime Stoppers is asking for the public's help as police try to solve the June 19 killing of 24-year-old Diaz Petty.
Petty was found at 11:07 p.m. that night lying on the ground in the 1000 block of Lysle Boulevard, suffering from a gunshot wound, police said. He was taken to the hospital but died of his injuries.
Allegheny County police homicide detectives are investigating. They say that Petty had been seen earlier in the evening with another man and a woman about a block away on Fifth Avenue. Petty and the other man were having an argument, police said, when gunshots were heard.
The other man fled the area and Petty apparently made his way to Lysle Boulevard, police said, where he collapsed.
Anyone with information concerning the homicide is asked to call Pittsburgh Crime Stoppers at (412) 255-TIPS. A reward of up to $1,000 is offered for information leading to the arrest and prosecution of individuals wanted for featured crimes. Callers may remain anonymous.
