The Murrieta Police Department is exercising extra security in the city and at schools in light of the multi-state and county manhunt underway for 33-year-old Christopher Dorner, a disgruntled ex-Los Angeles police officer suspected in three killings.
"We added extra security for schools and we have extra patrols working the city," said Murrieta police Lt. Rob Firmes on Friday morning.
Additionally, Firmes said three Murrieta officers, including a K9 unit, were en route to assist in the search for Dorner that since Thursday has been concentrated in the San Bernardino Mountains near Big Bear.
Dorner's 2005 Nissan pickup truck was found burned out Thursday in Big Bear, according to authorities.
Dorner is suspected in the ambush killing of a Riverside police officer early Thursday and the double-killing of a young couple in Irvine.
