VENANGO CO., Pa. (EYT) – The prosecution’s case against David Allen Bosley in the murder of Marcy Suzette Nellis seems strong. It includes DNA evidence collected at the crime scene linking directly back to him.

It’s important to remember, though, that David Allen Bosley is only “accused” of murder. If he’s convicted of the crime, then we can call him a murderer. Until then, what Lieutenant Cory Ruditis of the Oil City Police Department accused Bosley of in the criminal complaint against him is only alleged.

Bosley, though, has a long and violent criminal history in Venango County. Unlike the latest case against him (so far), Bosley was either convicted of or pleaded guilty to the charges against him in his three previous criminal cases.

Below is a timeline of the crimes Bosley has committed in Venango County.


June 30, 1990, about 2:30 p.m. – Bosley attacks a 40-year-old woman in Cranberry Township, Venango County.

According to the victim, Bosley grabbed her by the throat and forced her over a hillside where he told her he wanted to have sex with her. He let her go after she convinced him she wouldn’t tell anybody, the complaint states.
