Southern California authorities were investigating hundreds of tips Monday after offering a $1 million reward for information leading to the arrest of a fugitive ex-police officer wanted in the slayings of three people.

The manhunt for Christopher Dorner, 33, coupled with added security at Sunday's Grammy Awards, left the ranks of the Los Angeles Police Department stretched thin.

Along with responding to routine calls for service, police have been protecting dozens of families considered possible targets of Dorner, based on his alleged Facebook rant against those he held responsible for ending his career with the LAPD five years ago.

"Our dedication to catch this killer remains steadfast," Los Angeles Mayor Antonio Villaraigosa said. "We will not tolerate this reign of terror."

Police and city officials believe the $1 million reward, raised from both public and private sources, will encourage the public to stay vigilant.

"This is not about catching a fugitive suspect, it's about preventing a future crime, most likely a murder," LAPD Chief Charlie Beck said. "This is an act, make no mistake about it, of domestic terrorism."
