A child-killer who murdered his partner’s two-year-old son has been jailed for life and the child’s mother has been sentenced to eight years of custody for allowing the death of the toddler.

Sheffield Crown Court heard during a trial how Sarah O’Brien, aged 33, of Bosworth Road, Doncaster, and her partner Martin Currie, aged 36, of no fixed abode, denied murdering Ms O’Brien’s two-year-old son Keigan O’Brien in January after he died from head injuries.

But Currie was found guilty of murder by a jury and although O’Brien was found not guilty of murder she was found guilty of allowing the death of a child.

Both were also found guilty of cruelty to a child between July, 2019, and January, 2020.
