The Property and Evidence Department is responsible for all the property involved in criminal cases and for the many found property items turned in to Mammoth Lakes Police Department. Property is released by appointment only. The Property and Evidence Department can reached at (760) 965-3710. If you have property that belongs to someone else, California law requires you to turn it into law enforcement so that an attempt to return it to its lawful owner can be made. If no one claims the property in 90 days, the finder may claim it if the finder declares that intention when the item is originally turned into Mammoth Lakes Police Department.
