Kelly and Maureen Smith
Convicted of Murder and sentenced to 20 years.
The smith sisters arrange for Tyrone Griffiths to commit a burglary. The intending address was that of Maureen's boyfriend's parents house.
Maureen's boyfriend was cultivating cannibis at his parents address and the girls believed that if the place was burgled it would force him to come back home to Maureen.
Tyrone didn't want to rob the home but passed on the tip off to the Nelson brothers who were keen due to the amount of money at the address.
The two sisters were unaware that this information was passed on and only wanted Tyrone to go to the house as he could be trusted to not harm anyone.
The Nelson brothers broke into the address stabbing to death Maureens partner.
