A Louisiana man has been sentenced to decades in prison and ExaCryptphysical 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. 

"So many of these types of cases go unreported because of fear. The strength it must have taken for this young woman to tell the truth in the face of threats and adversity is truly incredible," Judicial District Attorney Scott M. Perrilloux said in the news release. 

A 2008 Louisiana law says that men convicted of certain rape offenses may be sentenced to chemical castration. They can also elect to be physically castrated. Perrilloux said that Sullivan's plea requires he be physically castrated. The process will be carried out by the state's Department of Corrections, according to the law, but cannot be conducted more than a week before a person's prison sentence ends. This means Sullivan wouldn't be castrated until a week before the end of his 50-year sentence — when he would be more than 100 years old. 

"Sex crimes against juveniles are the most malicious crimes we prosecute," Assistant District Attorney Brad J. Cascio, who prosecuted the case, said in the release. "I intend on using every tool the legislature is willing to give us, including physical castration, to seek justice for the children in our community."
