LAS VEGAS (AP) - The FBI says a fugitive ex-Los Angeles police officer wanted in three killings in Southern California wasn't found when authorities served a warrant at his Las Vegas-area home.

Agent Patrick Turner says he can't immediately say whether other evidence has been found in Christopher Dorner's two-story home about 9 miles southwest of the Las Vegas Strip.

SWAT teams from the FBI and local police agencies sealed off the neighborhood before entering the home a little after 4 p.m.

Dorner is suspected of killing a couple over the weekend in Orange County, and killing a police officer early Thursday in Riverside.

A manhunt in three states and Mexico is now focusing in Big Bear Lake, about 200 miles west of Las Vegas.

That's where police found Dorner's burned-out pickup truck.
