From what I understand:
He drugged up a black child
Fucked himself silly
Realised kid was not moving, but assumed it was due to the drugs.
Freaked real bad, when he saw the kid was dead.
Paid 7.3 million to get rid of the body.
They dissolved the body in HCL (Pool Chem),
which they then poured into the drains.
