Exactly how baby Maija Puhi-Duff received horrendous fatal head injuries isn't known but it's the Crown's contention it was her father who inflicted them.
The claim was made by Crown solicitor Amanda Gordon in the High Court at Rotorua when she opened the case today against Michael Donovan Duff, 42, who has pleaded not guilty to murdering the infant at Turangi on March 12, 2016.
Gordon told the jury of five women and seven men the baby's death had initially been treated as a cot death but a post mortem had revealed extensive bruising to her head, both above and below the skin and bleeding across the surface of her brain.
Medical evidence would be called to say the injuries had been inflicted by some form of blunt force causing severe trauma to Maija's head which wasn't consistent with being caused accidentally.
"The Crown sets out to prove he [Duff] assaulted her to the head because he was the only person with her in the hours leading up to her death, he assaulted her on the head and likely caused the death of a nine-month-old defenceless baby and is therefore guilty of her murder," Ms Gordon said.
