A Cañon City mother and her two children who were slain Sunday were identified Tuesday as Mandy Folsom, 35, Marissa Folsom, 9, and Mason Folsom, 5, Fremont County Coroner Carlette Brocious said.
Autopsies for the three victims will be conducted Wednesday, when the cause and manner of death will be determined, Brocious said.
Jaacob Harding Vanwinkle, 31, appeared in court in Fremont County Tuesday, records show.
Vanwinkle requested an attorney after he was advised that he faced three counts of first-degree murder, three counts of kidnapping, sexual assault and sexual assault on a child by one in a position of trust, records show.
Vanwinkle was arrested Sunday after a teen girl fled to a neighbor's house and reported that she had been sexually assaulted and the assailant was still at the house with other family members, according to Cañon City police. The three family members were found dead and Vanwinkle was taken into custody at the scene.
Fremont County Sheriff's officials said they were seeking an arrest warrant for Vanwinkle before he was apprehended. After moving from Indiana to Colorado, his sex-offender status required him to register four times a year. He was supposed to report to the sheriff's office on March 4 but never showed up, officials said.
Vanwinkle had dated the woman and was living in the family's home, police Sgt. Shannon Byerly said Tuesday. Autopsies were scheduled for Wednesday.
Vanwinkle faces charges of first-degree murder, kidnapping and sexual assault. A judge told him he could face the death penalty if convicted. Vanwinkle has applied for a public defender, but no attorney had been assigned to his case as of Tuesday.
The charges were the latest in a violent criminal history that spans a decade and at least two states.
Vanwinkle had been required to register as a sex offender since 2004, when he was convicted in Indiana of child molestation and other sex crimes involving girls as young as 5 and 7.
His next court appearance is scheduled for 8:30 a.m. Wednesday at the Fremont County courthouse.
