Authorities in Green County say four family members are dead after a plane crash in Southern Wisconsin.
The Green County Sheriff's Office says the crash happened just after noon Sunday about a mile from Monroe Municipal Airport.
They say the single-engine Cessna 182T went down in a field and struck some trees. They also say the pilot was a grandmother and the three passengers were her 17-year-old granddaughter, 13-year-old grandson and the teens' mother.
Federal officials are investigating.
