KANSAS CITY, Mo. (AP) — A woman who alleges that she was sexually assaulted more than 50 times while incarcerated at a Missouri prison is the fifth to sue a former guard amid a federal investigation of the facility.

The Kansas City Star reports that the latest lawsuit against Edward Bearden is set for trial in July 2021.

Bearden is a former guard at Chillicothe Correctional Center. Although, four other civil cases have been lodged against him, Bearden has not been criminally charged. The first of the lawsuits were filed mid-year, 2018.

The FBI and the Department of Justice have been conducting an investigation of the prison.
