A BABY died from an overdose of heroin, cocaine and methadone while his junkie mum binged on drugs.

Sabrina Ross left 14-month-old son Rio alone for nine hours as she shared 16 rocks of crack cocaine and two heroin wraps with a friend.

Ross, 30, woke from her spree at 10am to find Rio dead in his cot, cl**tching a Winnie the Pooh toy.

The former prostitute was jailed for five years yesterday after admitting manslaughter.

Bristol Crown Court heard Rio had been exposed to his mothers drugs for most of his life.

She often smoked heroin and crack near him. She also left bottles of the liquid heroin substitute methadone within his reach

She told cops she had previously seen the baby holding an empty methadone bottle.

Ross wept as judge Mr Justice Roderick Evans told her she killed her son by creating a completely unsafe environment.

He said: Rio was inhaling Class A drugs and there is reason to believe he ingested methadone. It was gross neglect that ended his life. Your child looked to you for protection and you breached that trust. No term of imprisonment can give Rio his life back.

On the night Rio died, Ross, of Horfield, Bristol, left her flat three times to buy drugs. Prosecutor Giles Nelson said: She was more concerned about illegal drugs than Rios welfare.

Ross currently has another baby in social services care.
