The pilot stated he was looking for an opening to get down through the clouds, and later started a descent to 6500. The radar controller noted the aircraft track going to the north and requested the pilot report when headed southbound again. Subsequently, the aircraft impacted mountainous terrain at 3600 feet, while headed in a northerly direction.
