Heartbreaking videos show little Preston Davy giggling and trying to say his first words before he was sent to live with the adoptive father who would sexually abuse, torture, and murder him. A tragic clip released by Lancashire Police today shows a happy and healthy Preston before he was taken out of foster care and moved into the home of Jamie Varley and John McGowan-Fazakerley. The little boy, who is wearing a yellow Batman jumper, was filmed playfully giggling and trying to speak, as he lies on someone's lap on the sofa. Toys can be seen in the background. In contrast, a horrifying video - filmed just months later and after he had moved in with Varley and his boyfriend - shows Preston being deliberately kept awake. In the upsetting clip filmed on the evening of June 15 - hours before Preston turned one - the tot can be seen desperately trying to sleep while Varley plays the soundtrack to the Disney film Moana loudly on the television.As he shuts his eyes, the evil former teacher shouts 'Boo', causing Preston, who is dressed in just a nappy, to startle awake.The harrowing video shows the sleep-deprived little boy, clearly confused and desperately tired, smiling as he tries not to nod off. Just weeks later, Preston was dead. Jamie Varley, 37, a former teacher, will die in jail after he was sentenced today to a whole life order for the killing of the 13-month-old baby boy during a sex assault in July 2023. His partner, 32-year-old sales manager John McGowan-Fazakerley, who was complicit in Preston's death and also sexually abused him, was sentenced to 25 years.Preston's short and tragic life was bookmarked by murder after he was taken out of the care of his mother - convicted killer Sarah Davey - at just five days old. He was placed into foster care before he was adopted by Varley and McGowan-Fazakerley when he was nine months old.
