Gregory Liascos of Portland earned the "Moss Man" moniker after police say he was arrested in full-body camouflage last October outside the Rice Northwest Museum of Rocks and Minerals.
Police say the 36-year-old Portland man had cut a hole in a museum wall and was trying to break in.
Officers found a bike and a backpack, but they didn't find the suspect until a police dog bit what appeared to be the ground. It was Liascos in a "ghillie" suit, a head-to-toe camouflage outfit used by military snipers to blend in with vegetation.
Liascos later said the whole thing was a mix-up, and that the outfit was a Halloween costume from his kids.
