They should also be using cadaver dogs during this search. He may have off’ed himself, having grown frustrated that they didn’t still couldn’t find him, thus producing the suicide by cop scenario he had expected.
That’s what I’ve been saying; cadaver dogs....or keep an eye open for circling buzzards. If he offed himself the buzzards will eventually show up. OTOH....he could be several states away by now, even on foot, while the LEOs keep tripping over each other within a mile of his parents’ home. Seems to me he’d be headed south.
On December 1 his partially decomposed corpse will be found by hunters on the opening day of rifle deer season.
