EXCLUSIVE Mum won't let knife attack destroy her:
The mother of a schoolboy stabbed to death for giving a teenager a "dirty look" last night said she forgave her son's killer.
Lorraine Dinnegan made the selfless gesture towards Joseph Chin, 16, after he was jailed for life yesterday for attacking Martin, 14.
She said: "I don't feel anger. I forgive Joseph for what he did.
"Forgiveness is part of the healing process. To be consumed by hate and revenge achieves nothing.
"I want to remember Martin for the beautiful person he was, and I don't want this to be clouded by hate.
"I just pray that his killer can now get the right help to enable him to become a better person and come to terms with the crime he committed."
But she said she wants to leave London.
Around 20 thugs cornered grade A student Martin near his home in Holloway, North London, after he gave the gang a hard stare from a bus in June last year. He ran but was punched in the head before Kevron Williams, 17, stabbed him with a screwdriver. Chin then finished him off.
Chin, of Finsbury Park, North London, will serve a minimum of 12 years' jail. Williams got four years for GBH.
Martin's parents Lorraine and James handed in a letter to Gordon Brown last year calling on him to tackle the scourge of knife crime.
