HATFIELD, Pa. (KYW Newsradio) — Jurors tasked with deciding the fate of a Montgomery County man who shot a guest at a party he was hosting last July heard differing accounts of the shooting from witnesses. 

Derrick Cosby was charged with voluntary manslaughter for shooting Jeremy Chasteen last July.

Jurors heard a reading of the interview Cosby gave to police the night of the shooting. He told police he saw Chasteen choke his wife and hit her more than once with a closed fist. He said after Chasteen pushed Cosby’s wife, Cosby pulled a gun he was carrying inside his wasteband and shot Chasteen in the head.

Cosby’s 25 year-old daughter said she saw Chasteen hit his wife multiple times and watched as he pushed, shoved and hit other guests. But Chasteen's widow testified her husband only grabbed her by the back of the neck to direct her out of the party.

Cosby claimed self-defense, but prosecutors pointed out Cosby never warned Chasteen he had a gun, and no one ever called police for help.
