Assuming they have the vehicle in police custody- can the internal GPS data be extracted to retrace their (vehicular) footsteps and piece together a timeline of their last days/hours of activity? This could reveal when they left home, where they went, and line it up with the new camera information to find the date/time and perhaps location & perpetrator of their demise. I'm sure phone data is also being collected and analyzed at this point as well, as we all know we're tracked wherever we go as long as we have a mobile phone on us. Hoping for a swift resolution to this devastating case.
