$1M reward for ex-LA police officer prompts tips

IRVINE, Calif. (AP) — A $1 million reward for a fugitive ex-police officer wanted in the slayings of three people took authorities to a San Fernando Valley home improvement store but so far prompted no credible leads in the search for Christopher Dorner.

The manhunt for him, coupled with the need for added security at Sunday's Grammy Awards, left the ranks of the Los Angeles Police Department stretched thin. A tactical alert began Sunday afternoon and remained in effect today for all city officers, which means they're staying on duty beyond their shifts.

Besides responding to the usual calls for service, police have been protecting dozens of families in the area considered targets based on Dorner's Facebook rant against those he held responsible for ending his career with the LAPD five years ago.

Among those Dorner, 33, is suspected of killing is a Riverside police officer, and on the fourth day of the manhunt, authorities put up a $1 million reward for information leading to his capture.
