NORTHERN CALIFORNIA – Federal, state and local authorities are searching the North State for a Shingletown man alleged to have shot to death his wife and two children.

The Shasta County Sheriff's Office said the search is on for 45-year-old Shane Franklin Miller, who is on the run after his family was found murdered in their Alpine Way home in Shingletown on Tuesday night.

Officials said a nationwide manhunt bulletin has been issued for Miller, whose wife, 34-year-old Sandy Miller, and the couple's two daughters, 8-year-old Shelby and 4-year-old Shasta, suffered multiple gunshot wounds. The weapon so far has not been identified or located.

Humboldt County officials reported that Miller's gold 2010 Dodge pickup was found abandoned near Petrolia on Wednesday.

Miller is described as a white male with red hair and blue eyes. He is 5 feet 10 inches tall and weighs 200 pounds.

He is considered armed and dangerous, possibly having access to a cache of weapons. The public should not approach Miller; if he's seen, call 911.
