A small plane crash in a remote mountainous region of Colorado likely killed everyone on board, authorities said Monday.
The Cessna 310 crashed Sunday in the San Juan Mountains, near Telluride, Colorado, National Transportation Safety Board spokesman Peter Knudson told NBC News.
The NTSB originally said five people were on the twin-engine aircraft when it went down about 4:35 p.m. (6:35 p.m.), but the San Juan County Sheriff's Office, which sent crews to the scene with Colorado National Guardsmen, said four people were on board.
"No survivors expected," the sheriff's office wrote on a Twitter account that a sheriff's office spokeswoman confirmed was operated by county officials. The remains of all of the passengers were extricated from the crash site by Monday afternoon, the sheriff's office said.
The victims of the crash had not yet been identified, Knudson said. He said the confusion about the number of people on board might be the result of an inaccurate flight plan filed with the Federal Aviation Administration.
A Cessna 310 en route from Flagstaff, Arizona, to Amarillo, Texas, was reported overdue by a relative of someone on the plane Sunday, FAA spokesman Ian Gregor told NBC News. Gregor said the FAA had not yet confirmed that the crashed plane and the plane headed for Texas were the same.
Investigators with the NTSB and FAA were expected to arrive at the crash site Monday night, Gregor said.
