A father who killed his 11-month-old baby son has been jailed for life.
Shane Anthony Hawkins was told he would serve a minimum of 14 years after a jury at Truro Crown Court found him guilty of murdering his son Kaydon.
The court heard that Hawkins, who was 22 at the time of the offence, was a physically abusive father who had told six different accounts of how his son ended up in hospital on December 11, 2010, and that bruises and marks on the baby suggested there was a history of assaults on Kaydon.
Much of the medical evidence suggested the boy's fatal head injury was not the result of an accident, the court was told.
Hawkins, who was living on the Kinsman Estate in Bodmin, and is now aged 25, maintained in court that he had accidently dropped Kaydon, and the baby had hit his head on a storage heater when he fell.
He died three days later at Bristol's Children Hospital from severe brain damage.
Kaydon had suffered retinal haemorrhaging in both eyes consistent with being shaken violently, the court heard.
The judge, Mr Justice Hamblen, said Kaydon's death had been caused by Hawkins shaking him violently when the baby's cries interfered with him playing a computer game.
"You were on your PlayStation and his interruptions angered you, and at some stage you flipped.
"Kaydon's death was caused by your hand, and it was not the first injury he received as a result of your violence against him,'' the judge told Hawkins.
The judge said although Hawkins had been "immediately remorseful'' for his actions, and called an ambulance straight away, he had caused his baby son's death.
Following the verdict the senior investigating officer, DI Jackie Swift, said: "This was a violent act committed against a defenceless baby who sustained fatal head injuries at the hands of the person who was there to care for him.
"In the subsequent investigation, Kaydon was also found to have suffered other injuries during his short life inflicted by his father.
"This was a complex and protracted investigation which was handled sensitively by officers from our Child Abuse Investigation Teams, supported by the Major Crime Team."
