PCP has its reputation for causing this type of dissociative- psychotic behavior.

I was lucky I only harmed myself,
back in 1974.
It must have been in the pot I had at a party.
I ended up doing a back dive onto the pavement, and then
rolling down a canyon full of cactus. ( so my best friend in 9th grade told me)
I had no recall of that part of the evening.
It could happen to anyone.
What a horrible thing, for this child, this man, and all involved.
