IDAHO FALLS, Idaho (AP) — Authorities have identified the four people on a small plane that crashed near Palisades Reservoir along the Idaho-Wyoming border, killing everyone aboard.

The Bonneville County Sheriff's Office in a statement Monday says two couples from Idaho Falls were on the craft that went down Sunday afternoon. Authorities listed those aboard as 40-year-old Jerry "David" Anderson, 38-year-old Jessica Ann Anderson, 39-year-old Thomas "Brook" Summers and 36-year-old Heidi Summers.

Authorities say additional investigation will include positive forensic identification of the bodies. Police say the four-seat Cessna crashed just minutes after taking off from an airport in Alpine, Wyoming, and was consumed by fire. The National Transportation Safety Board is investigating.
