Sheila claims that after she broke up with her boyfriend, Simon, two years ago, he bugged her car and has been sending her messages through her car radio. She says the messages contain “clues” to his whereabouts. She says she’s followed the clues – including driving 80,000 miles from Canada to Mexico – but hasn’t been able to connect with Simon face-to-face.

Sheila’s family and best friend claim she is delusional and says her constant search for Simon is ruining their lives.

Dr. Phil hired a private investigator to conduct a thorough inspection of Sheila’s car to determine if it has been bugged. See the results in the video above.
