The former sheriff once was a boxing club mentor to Maynard when the suspect was a teenager and when Crum was police chief in the town of Delbarton.
Last month, Maynard's family claimed that Crum had raped the man now accused of killing him and said authorities ignored his reports about the attack. Prosecuting Attorney Michael Sparks has said that he found no evidence to support either allegation.
Crum had been a county magistrate for more than a decade when he stepped down to run for sheriff last year. He took office on Jan. 1, just three months before he was killed.
Mingo County also has been rocked by the recent criminal indictments of a judge and a county commissioner.
Circuit Judge Michael Thornsbury has been charged with trying to frame the husband of his secretary for several crimes that federal prosecutors say the man didn't commit.
Thornsbury was allegedly having an affair with the secretary and enlisted the help of several others, including a state trooper and a former Mingo County homeland security official serving as foreman of the grand jury.
Commissioner Dave Baisden, meanwhile, was charged with extortion in an unrelated case.
Baisden and Thornsbury have pleaded not guilty and are awaiting trial.
