Another dead toddler.

Police have named the Morrinsville toddler who died in hospital on Saturday night. She was 22-month-old Hail-Sage McClutchie, of Hamilton.

Hail-Sage's family were known to Child Youth and Family.

"Although we have had no involvement with the toddler, her wider family is known to Child, Youth and Family," said general manager Lorraine Williams.

"My condolences are with those who loved and cared for her. We will continue to work alongside the police as they complete their investigations."

Residents near the Studholme St house in the Waikato town say they were told the toddler had brain damage when paramedics arrived on Saturday afternoon.

Police said Hail-Sage had serious injuries and said her death was suspicious. However, they remained cautious about labelling it a homicide. [+]
