Records Show Frank Sumner, Person Of Interest In Molly Bish Murder, Has Long Criminal History

WARREN (CBS) -- We're learning more about the criminal history of the man who is now a person of interest in the murder of Molly Bish.

Court documents show Frank Sumner was facing criminal charges before he died, including failing to register as a sex offender, making threats, disorderly conduct and harassment.

A former friend of Sumner's ex-wife told WBZ-TV he was controlling and stalked her.

"I did see his truck driving by my house constantly," Lisa Nelson said. "And then when I heard the clicking of the camera and saw him behind the tree taking pictures of obviously my daughter and his daughter swimming in a pool in bathing suits, I called the police."

Sumner was named a person of interest for the first time this week. Molly Bish disappeared 21 years ago this month when she was life guarding at a pond in Warren.
