Wisconsin plane crash kills 6, including Chicago-area school employees

PHILLIPS, Wis. — In a tiny Northern Wisconsin town, police and federal investigators are trying to figure out exactly what brought down a Cessna 421 plane early Sunday morning, killing all six people on board.

National Transportation Safety Board investigators say there was a discussion between the pilot of the plane and air traffic controllers about "local weather phenomenon." Soon after, the aircraft dropped off radar.

The Price County Sheriff's Office says the airplane crashed at 3:21 a.m. Saturday near the city of Phillips. On board were 56-year-old Thomas Demauro his 21-year-old son Klye, and Thomas' co-worker Chuck Tomlitz and his son George. They were traveling from the Waukegan airport to Canada for a fishing trip. The other two killed in the crash have not been identified, and at least one of them was the pilot.

Thomas and Chuck both worked at Tioga Elementary School in Bensenville, IL. Thomas was a PE teacher and Chuck was the maintenance director. The school broke the news to parents and students on its Facebook page, where comments poured in all day long.

The Demauro family wasn't up for talking on camera, but issued a statement-that said both Tom and Kyle will be deeply missed, and their heartfelt condolences go out to the other families involved, including their family at the school.

The NTSB is investigating along with the FAA. Funeral arrangements have not been made.
