On Saturday, more than 70 law enforcement officers were in the Mattole Valley and the Kings Range Recreation Area, also known as the Lost Coast, searching for Shane Miller.
Miller is accused of murdering his wife Sandy, 34, and their two daughters, Shelby, 8, and Shasta, 4, at their Shingletown home on Tuesday.
A spokesperson with the Humboldt County Sheriff's Office said S.W.A.T. Teams from the Humboldt County Sheriff’s Office, Shasta County Sheriffs Office, Sonoma County Sheriff’s Office and California Department of Corrections were on scene, along with law enforcement officers from Arcata Police, Eureka Police, Fortuna Police, Rio Dell Police, the California Highway Patrol, the Bureau of Land Management, CAL FIRE, and the California Department of Fish and Wildlife.
Also aiding in the search are helicopters from the California Highway Patrol and Kern County Sheriff’s Office, along with a team of United States Marshals, who brought a specialized communications truck with them.
According to the Sheriff's Office the Kings Range Conservation Area is 65,000 acres in size, and has no paved roads.
Officers are re-searching some areas that have been previously searched and are expanding their search area as well. They are also checking numerous cabins in the area. There has been no sighting of Miller since his truck was located in the 30000 block of Mattole Road on Wednesday.
