Waterford Township police say 35-year-old Aimee Louise Sword used the internet to track down a teenage son she gave up for adoption years earlier and had sex with him.

Sword surrendered on April 24 and is charged with third-degree criminal sexual assault.Police and prosecutors tell the Oakland Press that Sword put her son up for adoption more than 10 years prior to the assaults, but did not release his age.

Attorney Kenneth Burch says his client "maintains her presumption of innocence" and has had a hard time with the accusations.

Child Protective Services notified detectives about the situation.
