The women were attacked around 5 p.m. in the 29000 block of Central Avenue. Riverside County investigators said 25-year-old Connie Gonzalez was pronounced dead at the scene. Her mother, identified as 51-year-old Maria Gonzalez, was transported to Menifee Vallley Medical Center where she shortly succumbed to her injuries.
The suspect was described as a Hispanic man between 18 and 20 years of age. He was last seen wearing dark clothing.
Detectives did not reveal how the victims were killed.
"Both of these females were brutally attacked at the scene, and we're working that, we're trying to find out who that suspect is," said Riverside County Sheriff's Captain Scot Colllins. "We don't know if it was a random attack or if it was targeted."
