CREATED Feb. 12, 2013

California (KTNV) -- The manhunt continues for the former LAPD officer accused of three murders in Southern California.

Thousands of law enforcement officers are looking for Christopher Dorner, in what's considered one of the largest searches in California history.

Authorities are on high alert from the Mexican border to Los Angeles, and into the area of Big Bear Lake in the San Bernardino Mountains.

Dorner was formally charged Monday with the murder of a Riverside police officer and the attempted murder of three others.

He's also the prime suspect in the shooting death of a retired police captain's daughter and her fiance.

A $1 million reward is being offered for information that leads to Dorner's arrest.
