PENN HILLS (KDKA) – A 21-year-old man was found shot to death inside a vehicle in Penn Hills parked along Alcoma Drive early Tuesday morning.

Allegheny County Police are calling it a mystery — no suspects, no witnesses, just a dead body.

According to police, a neighbor called 911 after hearing multiple gunshots just after 1 a.m.

“Ironically, one of our patrol cars, one of our sergeants was driving by the area and heard three shots being fired,” Penn Hills Police Chief Howard Burton said.

Burton says in all, three shots were fired. The victim has been identified as 21-year-old Calvin Anderson, of Penn Hills, but he did not live on the street where he was found. He was pronounced dead at the scene.

Neighbors told police they had noticed the vehicle parked in that same spot earlier in the evening but thought nothing of it. Then about 45 minutes later, shots were heard.

“Eventually a neighbor came out and said he found someone in front of his house in his car that had apparently been shot,” Burton said.

One neighbor said detectives went door-to-door, asking people if they heard or saw anything.

“I’ve been up all night. Now. I’m scared yeah, I don’t know if they got the guy or not. It’s a quiet neighborhood, everybody’s friendly, nothing crazy like this ever goes on. It makes me a little bit nervous to hear this so close to home. And I have a daughter who is special needs. I don’t want anything happening to her,” Jacki Marquis said.

Detectives said a motive is not clear. Detectives also haven’t said if they have any leads on a possible suspect.

Anyone with information about this case is asked to call the Allegheny County Police Tip Line at 1-833-ALL-TIPS (1-833-255-8477). Investigators say callers can remain anonymous.
