A Larimer man walked into a Pittsburgh police station Monday, handed an officer a plastic bag containing a gun and said, "I am the shooter ... from the night before," according to court documents.
The suspect was 22-year-old Loc "Mike" Vong. The victim was an 18-year-old from Mount Washington who was dating a young woman Mr. Vong had dated.
Major Crimes Lt. Daniel Herrmann said Tuesday that surveillance footage shows the two were at the Brownsville Inn in Carrick together for several hours before Mr. Vong opened fire outside, killing Michael Palombia.
During that time, the lieutenant said, things seemed calm.
Mr. Palombia asked a witness, who is not named in court documents, to give him a ride home. But when that person returned in a car, Mr. Palombia walked up, opened the back door and said he no longer needed a ride, according to an affidavit of probable cause filed in the case.
Mr. Vong, who was in the back seat, asked Mr. Palombia to close the door because it was cold outside and the two began arguing and then fighting, police wrote.
Mr. Palombia said, "Oh, you got a gun. You got a gun. Go ahead do it, do it," according to the complaint.
The witness went to the bar to get the bouncer and heard two gunshots, police said.
Mr. Vong and the witness got back into the car and drove around the corner, where Mr. Vong was asked to leave the car, police wrote.
Homicide detectives wrote in the affidavit that they also spoke with a second person, in whom Mr. Vong confided shortly before he went to the police station.
Mr. Vong confirmed much of the original story and said that he dropped his gun and both he and Mr. Palombia struggled for it, according to the affidavit. Mr. Vong told the person that he grabbed his gun and fired several shots while Mr. Palombia rushed toward him, police wrote.
Mr. Palombia's father, also named Michael Palombia, said Tuesday that someone who lives near the bar told the family his son was running away when he was shot. He also said the police account "kind of sounds like my son, in a way."
Mr. Vong was being held in the Allegheny County Jail without bail Tuesday. He faces one count of homicide and a gun violation.
