Hearing delayed for man accused in Ann Arbor-area beating death
Kenney was critically injured Aug. 18, 2006, after being beaten and run over during a robbery at the dealership. He died 27 days later.
Roscoe was arrested days after the robbery and jailed for two nights, then released by Washtenaw County sheriff's investigators, who obtained a sample of his DNA. He maintained his innocence.
In September, he was charged with murder in the case. Sheriff's deputies said the arrest came after new evidence, but they have not elaborated.
Roscoe ran unsuccessfully for Putnam Township supervisor in 2006.
He faces up to life in prison if convicted.
