LONGMONT - A Longmont youth pastor is facing accusations that he had an inappropriate relationship with a teenage girl and spied on the victim from inside her home.

Jason Allen Roberson, 35, turned himself in at the Boulder County Jail Wednesday after police issued a warrant for his arrest.

Roberson is a youth pastor at VineLife Church in Longmont.

The victim is a 23-year-old Boulder resident who told investigators that she and Roberson had an inappropriate relationship that began when she was 15 years old and which continued for seven years. She says she trusted him as an authority figure and spiritual guide, and felt uncomfortable disclosing the relationship to others.

The victim said during their relationship, Roberson touched her inappropriately and watched her undress by spying on her outside of her home in Boulder. Roberson allegedly admitted to this behavior when confronted by the victim and family friends.

Roberson faces charges of sexual assault on a child by a person in a position of trust and invasion of privacy. Roberson was a close friend of the victim's family.
