I have not read this thread for some year or perhaps even two years now, hence am not sure if I ever brought it up, but I always found it extremely strange that the authorities who decided to use ground penetrating radar on the garage floor of the suspect and detected "anomalies" underneath it nevertheless decided not to dig to check what those anomalies were. Especially as they very obviously must have had a very good reason to use the radar in the first place, as investigators don't just randomly wonder if someone lays buried under someone's garage floor unless they have a reason for such a suspicion.
One might perhaps argue that it costs money to dig, however one would think that number one priority would always be to thoroughly investigate any lead that might aid to bring potential closure to family and loved ones, rather than just shrug at it?
