BUTTE, Mont. — A 44-year-old man has been sentenced to 30 years in the Montana State Prison for having sex with a 15-year-old stepdaughter.

The Montana Standard reports that District Judge Kurt Krueger suspended 30 years of a 60-year sentence he handed down Thursday.

The paper is not naming the man in order to protect the victim’s identity. The man had pleaded guilty to felony incest and faces separate rape charges in Idaho that also involve a family member.

The victim reported multiple rapes in Montana and Idaho. The man fathered children with the victim.

Besides the prison time, the man must complete two sex offender treatment programs before parole. And he must serve at least a quarter of the 30-year term before he’s eligible for early release.
