I suppose the fact that it was BM hired to bring in dirt for that jobsite, and what MG had to say about BM's behavior on the jobsite, had more to do with the search warrant than some elderly lady remembering hearing a sound one night that weekend. IIRC, she wasn't even entirely sure which night it was. Judges usually don't sign off on search warrants with that kind of "iffy" information.

Could BM’s truck gps have indicated to LE BM was there at the job site? Just thinking outloud. Moo
