He Plied a child with alcohol, drugged her and then raped and sodomised her. Throw away the key, he's vermin, talented vermin, but still low life.
She has rebuilt her life in the last 30 years but it probably took her a couple of decades to do so.
He should have had the guts to do his time or get treatment, he didn't. He may even have repeated his crime with someone elses daughter in a different country for all we know..
Hope he rots in Hell.
