Police focus on Mt. Vernon lake in searching for missing family

Listen to the Story

Police in Knox county are now focusing on a lake in Mount Vernon in the search for three people missing since last week. The move follows the discovery of a teenage girl, bound and gagged in a nearby basement.

A spokesperson for the state Division of Watercraft confirms the Knox County Sheriff’s Office requested a sonar-equipped boat to search a lake in Foundation Park, where an officer working overnight found what police say could be evidence related to the disappearance of Tina Herrmann, her son Kody and a family friend, Stephanie Sprang.

Meanwhile, 30-year-old Matthew Hoffman remains in custody today after police discovered 13-year-old Sarah Maynard, in his basement, bound and gagged. Hoffman has been charged with kidnapping Maynard, but Sheriff Barber says he’s hopeful Hoffman will provide information that could be helpful in the search for the three others still missing.
