A survivalist who allegedly killed his wife and two young daughters reportedly remains on the run seven months after the triple killing.

Shane Franklin Miller, 45, is the sole suspect in the May 7 shooting deaths of his 34-year-old wife Sandra and the couple’s two daughters, 8-year-old Shelby and 5-year-old Shasta, in the rural community of Shingletown in Northern California. The case is one of the few instances of gun violence against children in the United States that remains without an arrest since the Newtown shootings, NBC News reports.

“He better hope that the police get hold of him before a lot of the guys around here, because they would just as soon tar and feather him and string him up,” said Vera De Witt, president of a local nonprofit group raising money for a memorial for the girls.

De Witt said the killings shocked the town of 2,300 residents, generating “painful questions” for children and parents alike.

“Particularly,” she said, “little girls going home and asking, ‘Daddy, would you kill me, would you shoot me?’”

Miller, who disappeared into the rugged mountains of Humboldt County, with its hidden marijuana farms, remains on the U.S. Marshals’ 15 Most Wanted Fugitives List. Investigators have received thousands of tips – roughly 30 per day – but none have proven fruitful.

Authorities were called to the family’s residence for reports of domestic violence two weeks before the bodies were found. Investigators discovered Miller's abandoned pickup truck the next day near Petrolia, about 200 miles west of the home. But they have found no traces of Miller, despite the use of cadaver dogs and teams of investigators from several nearby jurisdictions.

"We're going up and down the area trying to figure out where he may have disappeared to," Humboldt County Sheriff's Lt. Wayne Hanson said in May.

Ground searches also included door-to-door checks of residences in the area and roadblocks were maintained on main roads between Petrolia and Ferndale in the event that Miller tried to leave the area.
