A three-year-old boy who was killed by his mother had more than 40 separate injuries to his body at the time of his death.
Mikaeel Kular was beaten repeatedly by Rosdeep Adekoya after he was sick three times following a family trip to a restaurant.
His condition deteriorated over the next few days, and his mother kept him off school and refused to take him to the doctors in the fear of his bruises being discovered.
He died two days later and his body was discovered by Adekoya.
The final cause of Mikaeel's death was found to be ''blunt force abdominal trauma".
