A registered sex offender with a history of mental illness was roaming the area with a BB gun and a knife, police said.
According to family members, Earl Sheldon Sorenson, 40, "considers himself a commando" when he is angry.
Sorenson is described as a white man, about 6 feet tall and weighing about 180 pounds. He has brown hair, blue eyes and a scar and tattoo on his left arm.
Police asked that residents be on the lookout for Sorenson and call 911 if he is spotted.
