Searchers located the wreckage of a twin-engine plane missing since Tuesday and the body of its pilot in a remote pasture in south-central Idaho, police said Thursday.

The pilot of the Piper Seneca was identified as 39-year-old Joe Jacobsen. Cassia County Sheriff Bill Crystal said the Boise man was killed on impact. The scattered wreckage was spotted by a Civil Air Patrol plane in a pasture between two mountains northeast of Albion about 1 p.m. Wednesday."Once we found the wreckage, we were able to drive right to it," the sheriff said.

The plane, carrying mail for Regional Express, a Boise-based company, was apparently forced down by severe weather, Crystal said. Further investigation of the crash will be conducted by Federal Aviation Administration and National Traffic Safety Board officials.

FAA spokesman Mitch Barker said Jacobsen radioed the Twin Falls airport Tuesday morning and reported he had "serious problems" with his aircraft.
