CAÑON CITY, Colo. -- Police in Cañon City have arrested Jaacob Vanwinkle as a suspect in a triple homicide Sunday night.
Vanwinkle, 31, was found inside a home where three people were killed. The suspect faces three counts of first-degree murder, three counts of kidnapping, sexual assault and sexual assault on a child by a person in position of trust.
He surrendered without incident, police said.
A mother, Mandy Folsom, 35, and her two children, Marissa Folsom, 9, and Mason Folsom, 5, died in the home. The cause of death was still being determined, but the case is being investigated as a multiple homicide, police said.
Officers were responding to a report of sexual assault on a teenage girl in the 1100 block of Phay Avenue when they discovered the bodies. The girl was reportedly sexually assaulted, but was able to flee to a neighbor's house, police said.
A man matching Vanwinkle's name and general description is a registered sex offender, according to a Colorado Bureau of Investigation records search. The record shows a misdemeanor assault conviction in Colorado related to domestic violence.
Vanwinkle was also convicted of several crimes in Indiana, including sex crimes against children, the Denver Post reported. Vanwinkle is involved in a child custody case filed in November 2013 in Adams County, and a permanent restraining hearing is scheduled for March 19, the Post reported.
The suspect was reportedly a family friend of the victims.
Cañon City Schools was aware of the situation and will have grief counselors on staff this week, officials said.
