A year on from the unexplained death of an infant in Dargaville, Police are appealing directly to the family to come forward, saying they are frustrated at the lack of co-operation from those present

Detective Senior Sergeant Kevan Verry, says the sudden death of 10-month-old girl, Kween Thompson, was reported to Police on July 13 last year, but it was not until days later Police were notified of potential unexplained circumstances.

One year on, Police are reappealing to the public for information.

Police say they're still very concerned about what happened on that night and are frustrated at the lack of co-operation they have been getting from those who were present when baby Kween tragically died.
