A Louisiana man has been sentenced to decades in prison and physical castration after pleading guilty to raping a teenager, according to a news release from the region’s district attorney.

Glenn Sullivan Sr., 54, pled guilty to four counts of second-degree rape on April 17. Authorities began investigating Sullivan in July 2022, when a young woman told the Livingston Parish Sheriff’s Office that Sullivan had assaulted her multiple times when she was 14. The assaults resulted in pregnancy, and a DNA test confirmed that Sullivan was the father of the child, the district attorney’s office said. Sullivan had also groomed the victim and threatened her and her family to prevent her from coming forward.
