PETROLIA — Authorities hunting for a Northern California man wanted in the killing of his wife and two young daughters have brought in dogs trained to search for cadavers.

A Humboldt County sheriff's lieutenant says that while investigators have no indication that Shane Franklin Miller may have taken his own life, the canines are part of a larger search through California's rugged and remote North Coast terrain.

More than 70 law enforcement officers are scouring the area for the 45-year-old suspected of killing his family last Tuesday in the rural community of Shingletown.

About 100 people attended a community meeting on Sunday. And while schools have reopened, authorities are asking people to be cautious in their daily activities and to stay in and lock their doors at night.
