Trooper Betsy Randolph said the 1964 Beechcraft Baron crashed Saturday afternoon near Mangum in Greer County, about 150 miles southwest of Oklahoma City. She said a witness reported the plane appeared to have engine trouble before it crashed.

Authorities identified the dead as: pilot Stephen Scott, 53, of Mangum; and passengers John Hall, 45, and Edi Ortega, 20, both of Altus.

Randolph said she didn’t know where the flight began or was headed.

A Patrol statement released early Sunday said firefighters used a tool to extricate the victims — who were all wearing seatbelts — from the wreckage. They were pronounced dead on the scene.

The Federal Aviation Administration is investigating and no immediate cause was given for the crash.
