Two suitcases full of methamphetamine were found in a Washington state forest on Monday, officials said — though it's still a mystery as to how huge haul of drugs got there.

The luggage was discovered in a "heavily brushy area" of the Okanogan National Forest, located in the north-central part of the state, near the town of Mazama.
