Police responded to the house after a unusual 911 call just before 1 a.m. local time when someone called from Denise Closs' cellphone, and the 911 dispatcher heard "a lot of yelling", according to records from the Barron County Sheriff's Department obtained by ABC News. Described as "5 feet tall and 100 pounds with strawberry-blond hair and green eyes", Jayme Closs is an 8th grader at Riverview Middle School in Barron. Authorities also tried calling the home's landline but it was disconnected, records show.
Barron County Sheriff Department deputies arrived at the Closs home within 4 minutes of a 911 call but found no suspects or gun at the scene and no sign of Jayme.
