A Washington County jury found a 22-year-old woman guilty last week of raping and sexually abusing a young boy.

Melissa Chacon of Cornelius went to trial on six Measure 11 charges related to sex abuse involving a 7-year-old.

The jury found her guilty Friday on three counts of first-degree sexual abuse and one count of first-degree rape. Judge Thomas Kohl acquitted her of using a child in a display of sexual conduct and jurors also acquitted her on one count of first-degree sexual abuse.

Her sentencing is set for Jan. 25 to allow time for a presentencing investigation. She faces a possible 25-year prison sentence under Jessica's Law, which applies to certain crimes against children younger than 12.

Hillsboro police began investigating Chacon after the victim disclosed the abuse to his mother, according to court records.

The boy's sister once found Chacon kissing him inappropriately and another time found Chacon in bed with the boy, records say.

In an interview with detectives, Chacon admitted to having sex with the boy, according to court records. She described various sex acts with the child that occurred multiple times early this year.
