Milton Trujillo, 34, was taken into custody in front of a store in the 44200 block of
Margarita Road in Temecula, according to sheriff's officials.
Trujillo allegedly gunned down an acquaintance, 43-year-old Carolyn Cagey, with a pistol in an open lot in the 2900 block of West Pala Mission Road about 3 a.m. Monday. Cagey died at the scene, Lt. Kenn Nelson said.
The motive for the slaying and the circumstances that preceded it were unclear, Nelson said. Investigators allege Trujillo shot Cagey multiple times while she was sitting in a parked vehicle outside her residence on West Pala Mission Road
