Help needed-I am looking for a specific photo from the Newhall crime scene for use in combat revolver training. Following the crime scene processing some of the officers' guns were placed on the passenger side floor of one of the CHP cruisers. In the photo I am looking for, one of the officer's Colt revolver can be seen with the cylinder open and a spent casing under the star. I have seen the photo but after hours of searching through thousands of photos in my books and on the web I am unable to find the photo again.
