Henderson had pleaded guilty to obstruction involving former chief magistrate Bryant Cochran.
A woman, Angela Garmley, who had appeared in Cochran’s court had accused Cochran of misconduct and although Cochran denied those allegations, shortly after winning re-election he resigned his post after admitting to presigning warrants.
Garmley was arrested on drug charges when drugs were found in a container attached to her car. The GBI later determined that the drugs had been planted and the charges were dismissed.
Henderson, a cousin of Cochran, and another former deputy, Josh Greeson, were both terminated for lying during the GBI’s investigation of the drug case. In his first interview with agents, Greeson said that he did not have prior knowledge of drugs being present in the vehicle. During a later interview he admitted that he did have prior knowledge and that is why he pulled the car over.
Greeson has said Henderson provided him with that information.
Cochran, through an attorney, has denied any knowledge of the drugs being planted in Garmley’s car.
Greeson’s sentencing is scheduled for June 28. Both face up to 20 years in prison and fines up to $250,000.
