District Attorney Warren Montgomery reported that a Washington Parish jury found Frederick C. Mangrum, 61, of Bogalusa, guilty Thursday of sexual battery of a victim under 13. Mangrum faces 25 to 99 years in prison when he is sentenced Sept. 18 by District Judge William Burris.

Mangrum was found guilty of committing sexual battery on a then-5-year-old girl in 2016. The defendant removed all the child’s clothes and then touched her inappropriately, Montgomery said.

The Bogalusa Police Department investigated the case with assistance from the Texas Department of Family and Protective Services, Children’s Advocacy Center in Belton, Texas, and McLane Children’s Hospital in Temple, Texas.

Assistant District Attorneys Iain A. Dover and Holly McGinness prosecuted the case.
