A joint investigation between the Montgomery County District Attorney's Office and Hatfield Township Police alleges that Cosby fatally shot Chasteen in the head after an altercation inside Cosby's home.
Cosby, a Navy veteran, allegedly called 911 at 11:45 p.m. to report the shooting. Police responded to the scene and found the victim in the family room, dead of an apparent gunshot wound to the head.
Cosby's lawyer released a statement to Action News, reading in part:
"My client believed that the shooting was justified as he was protecting his home and the people in it. The person shot was a physically imposing individual that was intoxicated and acting violently. He immediately called 911 and cooperated with the police."
He is currently being held on $75,000 bail.
