I don't know the area but I lived in So. Cali for 10 yrs. My advice is to move during the summer. Stay in an extended stay hotel, with a kitchenette, for a month or two. Get to know the area, read the paper, watch the news etc, drive around and look at neighborhoods. Drive through the local parks, look to see if there are kids playing at the park or if drug deals are going down in the park. This will give you the best idea of which areas are safe or not safe.
