Los Angeles County sheriff's deputies and animal control officers were searching by air Thursday for four pit bulls believed to have mauled a woman to death earlier in the day in the Antelope Valley community of Littlerock.
Hours after the attack, Los Angeles County Supervisor Michael D. Antonovich offered a $25,000 reward for information leading to the dogs' capture.
The 63-year-old woman was out for her morning walk about 9 o'clock when she was mauled by the dogs. Her name has not been released. She died en route to the hospital.
Sheriff's Capt. Mike Parker said a motorist saw the pit bulls attacking the woman and called 911. A deputy who responded saw one of the dogs, and the animal tried twice to attack the deputy. Parker said the deputy shot twice at the dog before it ran off toward the desert.
