PIERRE, S.D. (AP) - A federal jury in South Dakota has found an Alabama man guilty of various charges stemming from an incident in which he impersonated an FBI agent.
U.S. Attorney Brendan Johnson says 38-year-old Michael Thetford, of Alabaster, Alabama, has been found guilty of felon in possession of a firearm, impersonating a federal officer, interstate stalking, and tampering with witnesses.
The charges carry a maximum penalty of up to 38 years in prison. It's unclear whether Thetford has an attorney.
Johnson says Thetford showed up at the Hughes County home of William and Shirley Winslett in 2010, impersonated the agent, told them they needed to undergo a polygraph test and drove them around in a vehicle with locked back-seat doors.
Thetford was sentenced in Alabama last year to nearly 27 years in federal prison related to child pornography and other charges.
