That seems absurd. If the police had spotted a hand-to-hand, wouldn’t the police have made that claim immediately, rather than call his knife a switchblade, and blame his arrest on that?
If he had ingested a large dose of heroin, he would have passed out.
Not to mention that he was hogtied, by his hands and feet, on his belly on the floor of the van, head towards the front, in a space about 2 feet wide between the bench and the divider.
That interview was beyond comical. No rational person would buy that ridiculous nonsense.
You got a link showing he was left hogtied and on the floor of the van?
