Ian Hutchinson guilty of baby son Kieron's murder
A Barnsley man has been found guilty of murdering his seven-week-old son.
Ian Hutchinson was alone with his son Kieron when he killed the boy at his mother's house in Chapeltown, Sheffield, in September 2010.
The baby suffered a fractured skull and bleeding of the brain and eyes, which were associated with shaking. He died in hospital four days later.
Hutchinson, 24, was convicted after a trial at Sheffield Crown Court. He is due to be sentenced on Monday.
The jury heard Hutchinson may have killed his son out of frustration when he was unable to change his nappy.
Hutchinson told doctors and police that he had started changing his son's nappy after his wife and mother had left the house to go shopping, but found no baby wipes and so called his wife.
The defendant told police that his son had then become upset, coughed, went quiet and then stopped breathing.
Prosecutor Bryan Cox QC told the trial: "What precisely caused the defendant to inflict such serious injury to Kieron is not entirely clear.
"There must have been substantial violence.
"It may have been something as trivial as a sense of frustration that he'd been alone with Kieron without the wherewithal to change his nappy."
After the verdict, South Yorkshire Police described the case as "tragic" and said the investigation had been "sensitive and difficult".
'Progressing as expected'
Det Insp Ian Fidler said: "Our investigation established that Kieron had been seen by the family GP just hours before he was taken ill.
"He had undergone a thorough examination and was noted as progressing as expected for a child of his age.
"This family was not previously known to either police or social services.
"This case lay in the overwhelming medical evidence and who, other than Ian Hutchinson, could have been responsible for the injuries sustained by Kieron?
"The jury found that the rapidity of Kieron's demise could only have been at the hands of his father."
