    Details of Disappearance

    Stiles was last seen at her home on Orban Road in Grass Lake, Michigan on November 18, 2010. She lived with her boyfriend, Scott Steven Cassidy, and a male roommate at the time. The roommate stated he fell asleep on the couch and when he woke up about an hour later, Stiles wasn't there. She has never been heard from again. She left all of her belongings behind.

    A photo of Cassidy is posted below this case summary. He and Stiles had lived together for about a year and a half before she went missing, and he operated a tree service off of his property. Stiles has two children by other men. She was unemployed and didn't have a cellular phone or a car at the time of her disappearance. She and Cassidy were having financial problems and they apparently argued on the night she went missing.

    On November 24, six days after Stiles's disappearance, Cassidy was charged with auto theft. He allegedly stole a van from the Comtronics security company in Jackson, Michigan. He was on probation at the time for drug- and weapons-related offenses, and he also had a 1997 conviction for home invasion. On December 3, he hung himself in jail. It's unclear whether his suicide is related to Stiles's disappearance. He was one of the last people known to have seen her and the police interviewed him about her disappearance and had planned to question him further. He was never named as a suspect in her case.

    Although little information is available in Stiles's disappearance, her family believes she would not have abandoned her children and probably met with foul play. Her case remains unsolved.
