FARMINGTON, Utah (ABC4 News) – A convicted sex offender is accused of sexually abusing a woman with disabilities.

49-year old Jon David Stephens was charged Tuesday on charges of two first-degree felony counts of forcible sodomy and object rape and two third-degree felony counts of forcible sexual abuse.

According to charging documents, the incident happened in June when Stephens was helping the mom of the 18-year-old victim with some work around their house. The victim’s mom told police Stephens was aware that her daughter had an intellectual disability because they had discussions about it.

When the two were alone at the house, the victim told police Stephens took her into a bedroom and asked her “if she could keep secrets” before he sexually assaulted her.

A search of court records also shows Stephens was found guilty of gross lewdness in July 1992 and ordered to complete an in-patient treatment in Washington State. Stephens was later convicted of Lewdness involving a child in 1997 where he was placed on probation that was later revoked when he was found guilty of second-degree felony sexual abuse of a child in Feb 2000. He was then sentenced to one to 15 years at the Utah State Prison and released in 2001.
