Police are expected to charge the 49 year old woman from Nalawa, Ra, who allegedly murdered her 63 year old older sister yesterday afternoon, once the post mortem results have been released.

Director CID Waisea Vakamocea confirms the two had an argument and the younger sister used a kitchen knife to stab the elder sister.

It is alleged the 49 year old woman stabbed her sister in her back when she turned around to pick something up from the floor.
