SICKENING video shows a killer teacher deliberately keeping his adopted baby son awake just weeks before he sexually assaulted then murdered him.

Little Preston Davey was routinely ill-treated, sexually abused, physically assaulted and had indecent photos taken of him by Jamie Varley.

The vile teacher, who was yesterday found guilty of murder and sexual assault, also psychologically tortured the 13-month-old.

One clip released by police shows Varley, 36, forcing Preston to stay awake just hours before his first birthday.

The shocking footage also shows a toy falling on Preston’s head as Varley just films him.

Just weeks later, he was captured in harrowing CCTV rushing the “floppy” tot to A&E with his boyfriend John McGowan-Fazakerley.

The “hysterical” dad claimed he had left the baby in the bath while he had a shower and returned three to four minutes later to find him unresponsive.

In reality, Varley had sexually abused Preston before smothering the tot with his hand, fabric or by inserting an object into his mouth.

Medics worked for nearly an hour to resuscitate the baby on July 27, 2023, until a decision was made that further intervention was futile.

When told by doctors that Preston could not be saved, Varley pleaded with them to “kill me” and wailed loudly: “It’s all my fault”.

The teacher, who was wearing a red Jurassic Park T-shirt and tartan pyjama bottoms, was filmed sobbing loudly on the hospital floor.

Nurses and police could be seen trying to comfort Varley as he cried: “I can’t, no, I have done this”.

When one of the hospital staff told him that Preston needs him, he replied: “He doesn’t need me, it’s my fault…please get my mum…this is not happening…please kill me, please kill me.”

Varley eventually went to see and cradle his dead son but was heard saying: “I probably won’t see you again, I’m definitely going to hell.”

He continued to spread a web of lies about Preston drowning but the baby had dry hair, was wearing a nappy, the bath tub was empty and no water was found in his lungs.

Preston’s cause of death was instead given as an acute obstruction of his upper airway.

A post mortem found he had suffered 40 multiple non-accidental, internal and external injuries.

The jury heard some of these injuries showed clinical signs of sexual abuse, including “forcible penetration”.

Preston Crown Court heard Preston began living with the couple in their Blackpool home in April 2023 after undergoing an assessment and familiarisation process.

He had been removed from his birth mum Sarah Davey under an emergency care order.

Davey was yesterday revealed as a killer schoolgirl who tortured an OAP to death when she was just 14.

Just days after Preston moved in with Varley and McGowan-Fazakerley, the sickening campaign of torture began.

Varley, who took a year off work as head of year to adopt a child, confessed he was struggling with a lack of sleep due to the baby constantly waking in the night.

On April 6, he texted his sister, a baby sleep trainer: “He’s dead meat today. Didn’t sleep last night after 11.30. Up every, one and a half hours.”

Once in the couple’s care, Preston was taken to hospital three times – once with a fractured left elbow.

Preston had been described as a happy, smiley baby before he was placed in the couple’s care.

But after being adopted, he was said to look “blank” – a sign child abuse expert Dr Joanne Gifford described to the jury as “frozen watchfulness”, a trauma and stress response to child abuse.

The court was told Varley’s sexual interest in Preston was evident “within weeks” of his placement and that the teacher treated him as a “plaything”.

McGowan-Fazakerley “shared” his depraved interest, which was shown in indecent images and videos taken of the baby.

Police recovered a series of harrowing photos of Preston taken four days before his death, over a period of three minutes 12 seconds while he was being sexually assaulted.

Four days later, Varley recorded another video of Preston in extreme distress, hardly breathing and taking “agonal breaths” as he lay dying.

It has now emerged there were eight missed chances to save the tot before he was killed.

On one occasion, a hospital safeguarding team expressed their fears to Lancashire Constabulary but the matter was closed when a consultant said there was nothing to worry about.

Social workers also visited the couple and Preston at home several times before his death but failed to notice he was being abused.

Varley was convicted of murder, sexual assault of a child under 13, two counts of assault by penetration, grievous bodily harm, five counts of child cruelty and further counts of making, taking and distributing indecent images.

McGowan-Fazakerley was found guilty of causing and allowing the death of a child, three counts of child cruelty and sexual assault of a child under 13.

The evil couple will be sentenced tomorrow.
