From what I've learned today from the CNN Documentary and the SBSO Press Conference of CM's arrest: SBSO Inv Fisher (he's the lead Inv on this case) stated the state has evidence, that they believe that links CM to the murder scene (home). SBSO served 60 search warrants in this case, not including SDSO warrants. It NOW makes sense to me why Inv DuGal (SDSO) testified that he was investigating a missing persons case vs a homicide case and the home did not APPEAR to be a foul play/crime scene on his original investigation. SDSO did not attempt to process the home as a homicide scene, due to the lack of any visible physical evidence. However, once the bodies were discovered and SBSO took over the case as a KNOWN homicide case, SBSO did in fact serve search warrants on their home (years later) AND processed it as a homicide scene. This was stated by SBSO Inv Fisher. If Inv Fisher states they were killed INSIDE their home and it points to CM, they HAVE to have some evidence collected that makes them believe that, IMO. We are barely into the beginning of this case and I believe we WILL hear what they collected in the home that points to their murder AND CM's involvement. There is just so much speculation, including me, that we will have to wait to see what the Pros Team actually reveals in court. The Prosecution also does NOT want to reveal "their hand" during Opening Statements, IMO.
The SBDA's Office also assisted the homicide team investigating this case. I assume their investigators have ALSO collected evidence in this case.
