A man has been jailed for life with a minimum sentence of 17 years after murdering a toddler in a 'wicked attack' on two-year-old Rio Smedley.
Daniel Rigby, 23, from Tyldesley, Wigan, was found guilty of murdering his girlfriend's son by a jury of six men and six women.
Rio's mother Kirsty Smedley, 24, formerly of Cheriton Drive, Breightmet, Bolton, was also found guilty of allowing or causing the death of a child.
Mr Justice MacKay adjourned Smedley's sentencing to a date yet to be fixed for the preparation of a pre-sentence report, and remanded her into custody.
He told her: "I want you to understand that you stand in very real peril of a prison sentence as a result of this conviction. Don't have any delusions about it."
Sentencing Rigby Mr Justice David MacKay told him:
Rio had 91 separate injuries on his body and died from a ruptured liver, a trial at Manchester Crown Court heard.
The court was told that Rio's injuries were likely to have been caused by "heavy blows" from "punches, kicks, knees and stamping".
Simon Phillips QC, for the prosecution, accused Rigby of "striking Rio with such force as to split his liver in two" at around 4.30pm on April 22 this year.
He said the attack was part of "a sustained and violent attack".
He added: "A wicked attack on a defenceless two-year-old child."
Police also released CCTV footage of Rigby with the toddler the day before he killed him.
Speaking outside the court Greater Manchester Police made this statement on behalf of Rio's family:
