Heartbreaking family video captures tragic death of 3-year-old boy.

The biological mother of a three-year-old autistic boy, Harvey Borrington, who was killed by his stepmother, Leila Borrington, has released a family video showing some of the happy times she spent with her son before his tragic death. Leila Borrington was jailed for 15 years for manslaughter after slapping Harvey 'multiple times' around the head, having suffered two other attacks at her hands which left him with a broken arm and marks on his face. The video shows a healthy and happy Harvey giggling in the back of the car as he sips from his milky drink.
