THE mum and half-sister of a 16-year-old girl who died of a heroin overdose were jailed yesterday for not calling her an ambulance.

Andrea Townsend, 46, and Gemma Evans, 25, put Carly Townsend to bed to "sleep it off" but later found her dead.

Only days earlier the schoolgirl swore she was going to beat her smack habit.

But Evans helped supply her with the Class A drug, the court heard.

Judge Mr Justice Lloyd Jones said users Townsend and Evans would have known Carly had overdosed as they had both been through it themselves.

They were also aware she had at least two bags of heroin despite having no tolerance left for the drug and that one could kill her.

The women, of Pwll, South Wales, were convicted of manslaughter by gross negligence.

Evans was jailed for four years and Townsend for two.

Prosecutors earlier told Cardiff Crown Court Townsend was caught shoplifting and with a Class A drug four months AFTER her daughters death.

Her lawyers said she would be haunted forever by the tragedy.

But the judge told her: "You failed to care for your own child.

"You knew of her vulnerability."
