note: Wow Sylmar synchronicity ... I had prepared this message early this morning, but then got distracted by work. Now when I come back to post it, I see that other posterss found info about Sylmar too!
This is the explanation given for the search cancellation
I know about the official explanation, I just think it is a weak argument ... if Gavin went off a cliff, then searching some areas is better than searching no areas. If the cliff theory were true, then the reason why the cell phone stopped pinging off towers, would be that it was damaged in the car accident. Cell phone triangulation would give a relatively small area to search.
I think LE has done their due diligence and performed some helicopter searches, but ultimately they have discounted the theory that Gavin went off a cliff. And I think that where the cell phone last pinged led them to that conclusion. LE have not release ANY info about Gavin's cell phone records.
Gavin's sister once made a comment about his "last GPS location" being in Sylmar, CA around 4:30am on the morning of Wednesday 2 May 2012. This was pretty precise info ... but the remark was soon discounted as erroneous. I think the sister made 2 errors:
1-she let slip info that the police did not want released to the the public
2-she confused cell phone pings with a GPS system (which Gavin's car did not have).
My personal opinion is that his obviously distraught sister, perhaps not technically inclined, would place more importance on Gavin's last location, rather than the technical system providing that info ...so the location and time are correct.
Most of Sylmar is generally flat, except for the north section. Sylmar averages about 5500 people per square mile with a 70% Latino population [per wikipedia].
So if the cliff accident theory is discounted by LE, we are left with 2 possibilities:
1-Gavin voluntarily disappeared
2-Gavin was murdered.
While both options are undesirable, I try to keep #1 in mind ... because it would mean that Gavin is still alive and there is hope that the family situation can mend.
