“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.
