GRAND JUNCTION, Colo. — A small aircraft that was forced to land in Grand Junction after encountering bad weather during its trip from Alberta was reported missing and then found crashed in Utah after departing Grand Junction a day later.

The Civil Air Patrol said none of the four people on board the plane survived. The crash site is located in San Juan County, Utah.

Wednesday, four people left Canada in a Piper Lance headed south when the plane encountered conditions that grounded the plane in western Colorado.

The following day, 28-year-old Klint Kaupp, Tim Mueller, 28, Ron McKenzie and pilot Bill Kaupp departed the Grand Junction airport around 10:00 a.m. but had not been heard from since.

A tweet posted by Kaupp Family Farms on Friday appealed to the public for help locating employees at airports between Grand Junction and Albuquerque. The post said the family was flying their plane when it went missing around noon on Thursday.

The FAA told Canadian news source CBCnews that the organization is searching for the plane and U.S. Civil Air Patrol has been called out to help with the search which was focusing on southern Utah.

Crews decided to bring their attention to Utah based on radar and cell forensics recorded Thursday night, according to CBCnews.

A post on the Kaupp Family Farms Facebook page dated March 11, 2015 shows a picture of “our father Bill’s plane.”
