HELENA, Mont. (AP) — A 49-year-old Browning man has been sentenced to life in prison after being found guilty of sexually assaulting a 51-year-old woman last year.

The Independent Record reports (http://bit.ly/191iSmF ) Donald Carl Salois was sentenced Monday by U.S. District Judge Sam Haddon during a hearing in Helena.

Laura Weiss with the U.S. Attorney's Office sought the life sentence, saying Salois offered the woman a ride home in February 2012, but then took her outside a housing area and raped her.

Salois has previous convictions for sexually abusing one girl when she was 3 and another when she was 6. He served 10 years in state prison for those offenses.

Salois has been in custody since his arrest in August 2012. He was convicted of aggravated sexual assault in January.
