During the search, they found numerous items believed to be used in manufacturing weapons in a common room, according to the sheriff’s office.
The occupants of the house were detained and a search warrant was obtained so investigators could search the rest of the house. The cache of weapons and a pipe bomb were found in the room of Karl Waltenbaugh, 40, who had his 1-year-old child in the room with him.READ MORE: Firefighters Slow Advancing Willow Fire Burning In Steep, Mountainous Terrain Near Big Sur
