The Wisconsin Department of Corrections is housing a man who raped his own daughter in a women’s prison because he said he identifies as a woman himself—and the DOC is refusing to offer any kind of insight or explanation on the matter.

Mark Campbell is currently incarcerated in Taycheedah Correctional Institution, a women’s prison in Fond du Lac, Wisconsin, inmate records show. He is a registered sex offender convicted of first-degree sexual assault of a child.

That child was his own 10-year-old daughter, court documents allege.

Born in 1971, Campbell is currently 52 years old, weighs 225 pounds, and stands at 5 feet 9 inches, according to the DOC inmate locator.
