The search for triple-murder suspect Christopher Dorner kicked off shortly before 7 a.m. on Saturday, but there were no new discoveries, sheriff's officials said.

After heavy snowfall overnight, weather in the Big Bear Lake area where Dorner's truck was found cleared up Saturday morning and more than 100 law enforcement officers continued the search. At least 24 additional sheriff's deputies were sent to the area for added protection, and a helicopter equipped with FLIR technology that uses thermal imaging allowed operators to see body heat underground also joined the search, but did not turn up Dorner.

And there was no sign of him elsewhere in Southern California, despite many tips, said the Los Angeles Police Department's communications office.

Many mountain residents suspected Dorner was long gone, though.

It's time for life to get back to normal, said Big Bear resident Mary Frances, and Dorner should "act like a man" and turn himself in.

A Ford Explorer caught fire about 25 miles south of Big Bear Lake, but there was no connection to the search, said San Bernardino County Fire dispatch supervisor Kristen Anderson.

"There was nothing too exciting about it," Anderson said. "We got it out with no problem."
