A lonely teenager became a cold-blooded killer because he was suffering from the crippling psychological effects of being abandoned by his father, experts claim.
Schoolboy Michael Hamer, 14, killed 11-year-old cystic fibrosis sufferer Joe Geeling in a brutal attack in Bury, Greater Manchester, in March 2006, after luring the younger pupil back to his house with a letter purporting to be from the deputy headteacher.
He then subjected the boy, with whom he is believed to have had a ‘sexual obsession’, to a sustained attack, hitting him over the head with a frying pan before stabbing him 16 times. Hamer then dumped the body in a wheelie bin in a nearby park.
In TV show Killer Kids, experts put forward a theory that Hamer’s killer streak stemmed from a deep-rooted sense of shame and rejection that was born out of his father’s abandonment and later compounded by bullying at school.
The programme sees parenting expert Jo Frost meet criminologists and neurologists who examine whether Hamer, who is currently serving a life sentence, was born evil or if he became a product of his troubled childhood.

Frost says: ‘Trust me when I tell you that I do understand how frustrating adolescence can be. In all my years of working with children I’ve never knowingly met one capable of murdering another. Was Michael Hamer born with a lethal trigger inside him or did society turn this 15-year-old into a child killer?’
Michael Hamer’s policeman father left before he was born, which lead to him becoming a quiet and withdrawn boy.
Experts believe that Hamer, now 24, suffered from an attachment disorder that came from being abandoned by his father.
Dr Elizabeth Yardley, a criminologist, explains in the film: ‘His dad’s abandoned him so we’ve got essentially an attachment issue here, he’s not forming those attachments with that caregiver.
‘The relationships we have with our mums and dads are really important for shaping the relationships we go on to have with other people. Where we’ve got a problem with that [is that] it can lead to trouble down the line.’

Hamer’s quiet nature led to him being bullied by his schoolmates, who would call him names and steal the money he’d been given for lunch.
Dr Yardley surmised that this was another factor that lead to Hamer becoming a killer.
What we’ve got at the core of Michael Hamer is a real sense of shame. We’ve seen the seeds sown for that in the family with his dad kind of rejecting him, then we’ve seen that reinforced in the school environment where the kids are picking on him
Criminologist Dr Elizabeth Yardley
She said: ‘I think in this case what we’ve got at the core of Michael Hamer is a real sense of shame. We’ve seen the seeds sown for that in the family with his dad kind of rejecting him, then we’ve seen that reinforced in the school environment where the kids are picking on him. They’ve kind of picked up on the fact that there’s something a bit different about him and they’ve started targeting him.
‘Everywhere he turns he seems to be rejected; in the family, in the school environment, amongst his peers. He never really seems to find the place where he belongs, where he fits in.’
Hamer is said to have a developmental disorder and began hanging around with younger children, including Joe Geeling, who was in year seven at the time.

Experts believe that Hamer connected with a young group because they were at the same developmental age as him, but it has been suggested that he was sexually fixated on Joe.
On March 1 2006, Hamer gave Joe a letter instructing him to come home with him as part of a fake mentoring scheme.
Despite teachers telling him the scheme was fake, Joe still went back to Hamer’s home, where the older boy made a sexual pass at him.
Joe rejected him and told Hamer that he’d tell the whole school he was gay, which made him lash out.
Hamer hit Joe over the head with a frying pan so hard that it broke. He then ran downstairs and brought back a kitchen knife, which he used to stab Joe to death 16 times.

Hamer put Joe’s body in a wheelie bin and wheeled him to a nearby park, where he would be found the next morning.
A neurologist believes that Hamer’s killer streak may have been as a result of biology, and not his upbringing.
Professor Francesca Happé said: ‘One theory of what’s going on in adolescence is that the limbic, the emotional brain has matured and is really active, really full of desires and your frontal lobe hasn’t developed yet so it’s not able to reign in that emotional brain, so you get risk taking, impetuous behaviour.’
Hamer, now 24, was sentenced to life, with a minimum of 12 years – a tariff later increased to 15 years by the Court of Appeal.
Last year he had his early release plea rejected by a judge, meaning he will stay in prison until at least March 2021.
