When they arrived, they found the victim, Jessica Tinoco, 34, suffering from multiple stab wounds to the face, chest and abdomen. She was taken to the hospital but did not survive her injuries.
Raymond Rivas, 34, is now being charged for murder. He was booked into the Ventura County Main Jail and was placed on a hold for violating probation.
