CAÑON CITY, Colo. -

A 31-year-old man suspected of killing a mother and her two young children in a Cañon City home is expected to plead guilty.

The Cañon City Daily Record reports a motion filed Wednesday states Jaacob Vanwinkle wants to plead guilty to all charges against him, including multiple counts of murder, kidnapping and sexual assault.

Vanwinkle, a sex offender from Indiana, is accused of fatally stabbing 35-year-old Mandy Folsom, 9-year-old Marissa and 5-year-old Mason on March 9. Police were responding to a report of a sexual assault from a teenage girl when they found the bodies. The girl escaped and ran to a neighbor's home.

Investigators say Folsom and Vanwinkle had broken up two weeks before the murders.

Vanwinkle is scheduled to appear in court Monday.
