PIERRE, S.D. (AP) - A state inmate has been convicted of threatening to sexually assault and kill an employee of the prison.

Forty-three-year-old Joshua John Armstrong was convicted Tuesday by a Minnehaha County jury of making the threat.

South Dakota Attorney General Marty Jackley says Armstrong is a convicted sex offender. In August 2016, he wrote letters threatening the employee. Armstrong’s sentencing is scheduled for July 9.
