ARVADA, Colo. (AP) - A 40-year-old Arvada woman who police say wanted to be seen as a, "cool mom", is suspected of supplying drugs and alcohol to high school boys, and having sex with them. Sylvia Johnson faces charges of sexual assault and contributing to the delinquency of a minor. Police say she had parties for the boys almost every week between October 2003 and October 2004. She's accused of giving them marijuana, methamphetamine and alcohol. Investigators said Johnson told them she wasn't popular in high school, but recently felt like "one of the group." Police began investigating her after one of the boys told his mother about the alleged encounters. A preliminary hearing in the case is set for next month.
