Anthony Stocks allegedly threw a ten-year-old boy off a cliff in Brighton.

The boy tried to stop Stocks from raping his sister.

Stocks had reportedly groomed the young girl and claimed he was going to marry her.

Witnesses heard a shriek before seeing the boy fall and sustain serious injuries.

Stocks had considered throwing the boy into a quarry before pushing him off the cliff with intent to kill.

Despite surviving the fall, the boy has no memory of the incident due to high impact trauma.

Stocks denies charges of sexual assault, rape, attempted murder, and cruelty to a child.

Stocks claims he is not sexually attracted to children.

The trial is ongoing.
