An 18 year-old Longview man is being charged with multiple counts of child rape and molestation, accused of sexually assaulting a 13 year-old Kelso girl several times during the spring. It’s alleged that David Michael Cahill, 18, forced the autistic girl to perform oral sex on him as they walked through an alley to Vacation Bible School in April of this year. Kelso Police say that Cahill knew that the girl was severely autistic, reportedly having the mental capacity of a six year-old. Police also say that Cahill has some mental issues, but is considered to be “highly functioning,” and was aware that what he was doing was wrong. Authorities learned about the alleged abuse after several in-depth interviews with the girl, after she had told a school counselor that “a man had been touching her.” Cahill was arraigned yesterday in Superior Court, and was released on his own recognizance, with strict orders to avoid contact with the victim and other minors.
