Perhaps this is the homeowner cooperating, ie giving permission so no warrant needed.Really curious, and maybe one of our verified lawyers can chime in here (@gitana1 @Alethea @Chomsky ) but...
What kind of evidence does an investigation require, to persuade a judge to sign off on a warrant that requires the destruction of personal property, as in tearing up a newly laid concrete patio, or a new in-ground pool (totally speculating here)?
I mean, this isn't "we need to poke around in the shed". This is, "we need to rip up this $40K home improvement you just had done".
Seems like that would require some hefty evidence, yes?
Even so, police wouldn't invest this kind of resources on a vague tip, they'd want strong leads.
Another note, wouldn't this be patio or path concrete, rather than a deep foundation? In that case there would be a burial and thin concrete over top, could be done by one person.
