Daniel Messel, 52, was sentenced to 15 years in prison Tuesday morning after pleading guilty to a felony battery charge.
Messel originally faced charges of rape, criminal confinement, criminal deviate conduct, battery with injury and theft for an incident reported in 2012.
He was convicted in 2016 for the murder of IU student Hannah Wilson, who died three years to the day before his Tuesday appearance for the unrelated incident.
Messel pleaded guilty to an amended charge of felony battery resulting in serious injury. He will serve eight years for this charge and seven more for being a habitual offender. This time will be served concurrently with his 80-year sentence for the murder of Wilson.
