A convicted killer faces a return to jail after allegedly failing a drugs test.
Life parolee Melissa Anne Wepa spent 15 years behind bars after killing a friend who dobbed her in to police.
The 44-year-old stabbed Porirua woman Caroline Gardiner 50 times before dumping her body down a bank.
Nine months into her life sentence, Wepa - who had affiliations to the Mongrel Mob and Deadly F***ing Bitches gangs - was also charged after nearly biting off another inmate's nipple during a fight.
In 2005, she escaped from prison with another inmate when they used a dummy in their cell beds to fool guards.
