WABASH, Ind. -- A small plane crashed Saturday night, killing all four people on board.

Police said the plane went down just after 9 p.m. near West County Road 500 South in Wabash County.

The plane, 1967 Piper Cheyenne Six, was found in a bean field, police said.

Officials believe the plane’s right wing first made contact with the ground. Then, the plane flipped over and caught fire.

The four passengers were identified as John Swan, of Wabash, Kathy Swan, of Wabash, James D. Swan, 25, of Wabash and Vanessa Baer, 22, of North Urbana.

Officials said the group was returning home after a dinner trip.

Kathy Swan was a business teacher at Wabash High School. Classes there were cancelled on Monday.

The National Transportation Safety Board was investigating to determine a cause of the crash.
