Reading from a statement he said: "Dear ex-Mother.
"What you did to me is unforgivable. You beat me, starved me, almost chopped my penis off, threw my clothes away, wouldn't let me bathe. You almost killed me by having me take three (antidepressants) and two muscle-relaxers.
"Now that I know you're a complete criminal and only wanted me dead so you could go back to your old life.
"You won't be able to attend my graduation or see me go on to college, so I wish you goodbye. I hope you realise you have lost everything you had."
