BLOOMINGTON, Ind. (AP) — A man serving an 80-year sentence in the killing of an Indiana University student now faces charges in the sexual assault of another IU student.

Monroe County prosecutors charged 51-year-old Daniel Messel with attempted rape, criminal deviate conduct and several felonies stemming from the September 2012 attack on a 22-year-old woman.

The Indianapolis Star reports court documents filed Friday say a DNA analysis linked Messel to samples taken from beneath that woman’s fingernails.

Messel was sentenced in September to 80 years for the April 2015 slaying of 22-year-old Hannah Wilson and for being a habitual criminal. The 22-year-old from Fishers, Indiana, was slain two weeks before her scheduled graduation.

The woman sexually assaulted in 2012 told investigators that testimony in Messel’s trial was “eerily similar” to her own case.
