well, the SLO PD and SLO Sheriffs are not the best invesigative body in CA. I remember when two other girls disappeared later, the local authorities were frozen. Eventually the FBI was called in, and after looking who was recently parolled into the area, solved the crimes in a week. That area seems to have a lot of student murders, suicides, etc.
