BIG BEAR LAKE, Calif. (AP) - More than 100 officers fanned out again at daybreak in the snow-covered San Bernardino Mountains, resuming the search for the former Los Angeles police officer suspected of going on a deadly rampage to get back at those he blamed for ending his career.

Authorities hope clearer skies will allow aircraft to help them in the manhunt for Christopher Dorner, which entered its fourth day Saturday.

Relentless snowfall on Friday grounded helicopters with heat-sensing technology and hampered their effort to find Dorner, whose burned-out pickup truck was found a day earlier in this ski resort town.

SWAT teams in camouflage scoured the mountains, aware to the reality they could be walking into a trap set by the well-trained former Navy reservist who knows their tactics and strategies as well as they do.
