OMAHA, Neb. (AP) — A judge has set bail for a 21-year-old man charged in connection with a triple homicide at a house party in Omaha last month.

Trenelle Miller is charged with possession of a gun by a prohibited person. On Thursday, he made his first court appearance, and Judge Susan Bazis set his bail at $100,000.

Prosecutors say Miller had a gun at the Jan. 24 party and allegedly told witnesses he was “pretty sure” he shot someone before being shot himself.

His mother said after the hearing her son didn’t have a gun at the party and didn’t shoot anyone.

Nineteen-year-old Jakela Foster, 24-year-old Latecia Fox and 26-year-old Cameron R. Harris died in the shooting. Miller was one of five other people wounded by gunfire at the party.
