The 47-year-old was found dead on the floor of an RV on Guys Run Road in February 2020, police said.

Shane told police an argument turned physical and he hit his father twice with a fire extinguisher before shooting him in the head, according to the criminal complaint.

When Shane turned himself in, police said he told investigators it was an accident.

In connection with his guilty plea, the Allegheny County District Attorney’s Office said he was sentenced to 10 to 20 years in prison.
