The Trigana Air Service flight was en route from Jayapura to Oksibil when it lost contact

An initial search was suspended due to bad weather and nightfall, an official says

Jakarta, Indonesia (CNN) Indonesian searchers believe they have located debris from an airliner that crashed in a mountainous area with 54 people on board.

A search plane spotted the wreckage Monday, but a ground team hasn't yet been able to reach it, said Raymond Konstantin, an official for Indonesia's search and rescue agency.
