Wilson, 20, is charged in the June 3 shooting death of Kevin I. Smoot in Lancaster, Calif., about 75 miles northeast of Los Angeles. He also faces a special allegation that he personally and intentionally discharged a rifle.
He pleaded not guilty earlier this month.
Wilson surrendered to California authorities on June 12 and was suspended from the UM football team a few days later.
He remains jailed pending an Aug. 14 hearing in Lancaster Superior Court.
Smoot had been fighting with his girlfriend, Wilson's aunt, the night he was shot, authorities said.
