Even to merely question people, there must be “reasonable suspicion”, with specific reasons which can be articulated. Hunches, notions, forebodings, visions etc. will not do it. To go further requires probable cause . . .
The narrative here does not make sense. None.
From what I heard here in Austin at 6:16, KLBJ-AM, was the psychic ‘received’ the location, notified the local sheriffs AND three media outlets. The police went to the first location, nothing. Then had had reason to go to an adjacent property, and that’s when the the story was deemed bogus.
