Police investigating the death of a 2-month-old baby do not know where she was fatally injured or in how many houses she lived during her short life.
Hinekawa Topia, a triplet, died in Wanganui last week from what is believed to be a non-accidental head injury.
Police have so far had co-operation from family members as they seek information about how Hinekawa was injured, her movements and health in the weeks before she died.
The movements of the child will be crucial in solving what happened to her, police say, but few details have yet been confirmed.
The other triplets, both girls, were admitted to hospital after her death to have their health assessed as a precaution and were yesterday discharged into Child, Youth and Family care.
