Officials with the Chesterfield County administration say Captain Robert Lee will be sworn in as interim Chesterfield County sheriff at the courthouse Friday at noon.
Governor Nikki Haley is expected to sign an executive order naming Lee to the position.
Lee is a Captain with the South Carolina Highway Patrol.
Chesterfield County Coroner Kip Kiser has been serving as acting sheriff since the suspension of Sheriff Sam Parker last month.
Gov. Haley suspended Parker from office following his indictment on misconduct charges.
Prosecutors say Parker used state inmates to work on his home and personal property and allowed the inmates to live outside jail, go shopping and eat at restaurants.
Authorities say he allowed hand-picked inmates to live in a dorm, have televisions and an iPad, go on trips to the lake, and spend holidays with his family.
The indictment details special treatment Parker gave two inmates. One was serving seven years for drug trafficking. The other was sentenced to 15 years for arson.
Investigators say Parker let the inmates drive sheriff's office vehicles, have unsupervised visits with women and drink alcohol. In exchange, the men did work on Parker's home and helped him and his wife decorate for parties, they say.
Authorities also say Parker gave weapons to friends with no law enforcement training.
Parker faces four counts of Misconduct in Office and two counts of Furnishing Contraband to Inmates. Each charge is a misdemeanor, carrying a possible sentence of up to ten years in prison.
