Police say they found a man's body in the back of an SUV they stopped for missing a front license plate in the north-central Ohio city of Marion.

Police say the vehicle was searched after the officer who made the traffic stop early Sunday thought the three occupants seemed nervous.

Twenty-six-year-old Cliff Rick has been charged with murder, while 26-year-old Heidi Thacker and 31-year-old Michael Foreman are charged with evidence tampering.

Police Maj. Bill Collins said it appeared the dead man was shot in the head, but authorities are awaiting autopsy results on precisely how Sidney Bell died. The 26-year-old Chicago native had been living in Marion.

The three jailed suspects are expected to make initial court appearances Tuesday.
