A King's Lynn father killed his six-month-old daughter by shaking her or striking her head against a surface causing her 'irreparable' brain damage, a jury heard.

Officers were called to the Queen Elizabeth Hospital in King's Lynn, Norfolk, after Milana Guzas was admitted with suspected head injuries on February 26.

She was transferred to Addenbrookes's Hospital in Cambridge, where she died on March 2 last year, after her life support equipment was turned off when it became clear she could not be revived

Arunas Guzas, 40, of Greenland Avenue, King's Lynn, has denied manslaughter.

Karim Khalil QC, prosecuting at Norwich Crown Court, said medical staff became suspicious after Guzas brought Milana into the hospital claiming the baby was asleep on his chest when she let out a cry and became stiff and unresponsive.

However a scan showed Milana had suffered bleeding on the brain and was in a very dangerous condition.

He said she was transferred to Addenbrooke's and worrying evidence was found of 'non-accidential injury'.

Mr Khalil said the explanation given by Guzas kept changing and he told various stories including saying that he had fallen asleep and woke up to find her on the floor.

He said: 'His story changes over time, telling different people what happened. We say this changing story emerged as troubling and revealing aspects of damning medical evidence emerged.'

He said: 'Our case is that the defendant shook Milana or caused her head to strike one or more surfaces.'

Mr Khalil said the injury had caused irreparable brain damage which led to her death.

Mr Khalil said Guzas and his partner, the mother of Milana, had both been working factory shifts and sharing childcare duties for Milana.

He said the incident happened while he was alone with Milana but rather than phone 999 he had tried to contact his partner and claimed to have massaged the baby and put her in a shower to revive her.

Mr Khalil said in interview Guzas had denied any mishandling of Milana and claimed that he had not said at first about her falling off the bed as he was worried about her injuries.

Mr Khalil told the jury that the prosecution case was that such catastrophic injuries could not have been caused by a simple fall from the bed.

The trial continues.
