Three people were at home when Hutt valley toddler Ruthless-Empire was fatally injured according to police, so why more than a week on, hasn't anyone been charged?
The trio have been identified as persons of interest in the investigation, and are offering various degrees of co-operation.
The death of Ruthless-Empire Ahipene-Wall, also known as baby Ru, is being treated as a homicide after post-mortem results confirmed he died of blunt force trauma with several external injuries to his body.
Injuries that police say occurred up to 12 hours before he died.
Following the killings of baby twins Chris and Cru Kahui in 2006, the Crimes Act was amended making it an offence for anyone over the age of 18 living in the same household or closely connected to a family, to fail to act on child abuse they are aware of.
Jo Wickliffe is a criminal defence barrister and she speaks to Lisa Owen.
