Mark Simpson denied murdering Alexis Matheson, the daughter of Ilona Sheach A man has been found guilty of murdering a six-week-old baby girl in Aberdeen.
Mark Simpson, 29, denied murdering his then-girlfriend’s daughter Alexis Matheson by assaulting her in 2007.
The jury returned a unanimous guilty verdict on their second day of deliberations at the High Court in Aberdeen following a six-week trial.
Lord Uist jailed Simpson for life, for a minimum of 20 years, and also called for a fatal accident inquiry.
The case had begun on 12 October.
The Crown had urged the jury of six men and eight women to convict Simpson for his “wicked recklessness”
But the defence argued there was no sufficient corroborating evidence to say Simpson – who turns 30 on Sunday – even assaulted the baby.
Simpson denied murdering Alexis by assaulting her between 8 November and 9 December 2007.
The charge stated he seized hold of her, shook her and compressed her chest, leaving her so severely injured that she died.
Simpson has claimed during the trial the baby’s mother Ilona Sheach played a game called “fishy” where she lay on the floor and held Alexis above her.
He said Ms Sheach regularly shook the baby without supporting her head.
However, Ms Sheach said she would not have done anything to harm her child.
