Jaacob Van Winkle, the man accused of killing a Canon City mother and her two young children and sexually assaulting the woman's teenage daughter, pleaded guilty Monday in exchange for a life sentence in prison, the Canon City Daily Record reported.

A Fremont County judge accepted Van Winkle's guilty plea to 36 charges, including: 14 counts of first-degree murder, six counts of sexual assault, two counts of child abuse resulting in death, two counts of second-degree kidnapping, first-degree sexual assault, sexual assault on a child, sexual assault on a child by one in a position of trust, sexual assault on a child by one in a position of trust - pattern of abuse, and unlawful sexual contact.

Van Winkle will be sentenced in September.

Mandy Folsom, 35, and two of her children, Marissa, 9, and Mason, 5, were found stabbed to death in a bedroom of their Canon City home on March 9 after police got a call from the teen girl who had escaped to a nearby residence.

According to the Daily Record, a motion was filed in the Fremont County courthouse Wednesday, stating that "the defendant, through counsel, has informed the district attorney of his desire to waive the preliminary hearing and to enter a guilty plea to the charges as filed."

Van Winkle, 31, is being held at the Fremont County jail without bond and is also held on suspicion of failing to register as a sex offender after moving to Canon City. He was convicted in 2004 in Indiana of child molestation and other sex crimes involving girls as young as 5.
