Bridger was immediately the chief suspect. He wove an elaborate and fantastical defence initially while being interviewed by police, thwarting any hopes of finding the child alive, and then during the course of the month-long trial during which he broke down repeatedly. Yet despite the outward display of regret, he showed no regard for the heartache that his obfuscation and lies heaped on April's grieving family.
His claims that she had died in a road traffic accident with his Land Rover Discovery, and that his inability to recall what he had done with her body because of panic and alcohol, were as risible as they were calculated. Bridger's distinctive vehicle had been spotted by April's friend on the night she went missing. Her blood was discovered throughout his home, mainly concentrated in front of the stove where fragments of a child's skull were also recovered, along with a charred boning knife.
Although he was to prove every parent's worst nightmare, the powerful 1.8m man was a trusted figure on the Bryn y Gog estate, where he had had relationships with at least two women and used to invite children over for sleepovers at his house.
The father-of-six - the product of four relationships - was also well known to the Jones family.
He claimed to have been a Facebook friend of April's mother Coral, with whom he used to exchange greetings in the street after helping her with her car. The child's father Paul was a former friend from when the two men dated local sisters.
Yet the family knew nothing of his compulsions, believing him to be a former serving officer with the SAS who had trained in exotic locations around the world, a myth he perpetrated after arriving in Mid-Wales in the late 1980s.
Unlike the idealistic alternative lifestyle brigade who flocked to the picturesque town at around the same time, gun-obsessed Bridger had a long criminal record which he had begun to accumulate from the age of 19.
He had pleaded guilty to a string of offences, including attempting to take a car, possession of a firearm, having an imitation firearm, theft and two counts of obtaining property by deception. But though he was regarded as a drinker with a short and often violent temper, particularly directed against women and on one occasion a fellow motorist in a road rage attack, he was never considered a risk to children or convicted of a sexual offence.
The college drop-out had drifted through a series of jobs, including an unsuccessful stint with the London Fire Brigade.
After moving to Wales following a row with his family in Surrey, he worked as a lifeguard, a slaughter house worker and in forestry - an occupation which gave him specialist knowledge of the tracks and hills surrounding the market town.
Bridger's personal life had begun to unravel in the months leading up to the murder.
On the day of the killing, as he sent angry text messages to an ex-girlfriend and tried to arrange dates with a number of other women whom he hit on at random, he spent time viewing his collection of child pornography.
The disturbing cache included 65 criminal-standard abuse images. Carefully categorised into folders were pictures of Soham murder victims Holly Wells and Jessica Chapman and British schoolgirl Caroline Dickinson who was raped and killed on a school trip to France in 1996.
The illegal pictures were kept away from holiday snaps in anonymous files, including one marked "Z0" that contained obscene imagery of child abuse.
Another was marked "clothed" and the other bore the name of April's 16-year-old half-sister who he had described as "beautiful" and an "up and coming model". She had earlier refused a Facebook request to befriend the 47-year-old on the advice of her mother. Bridger set his own Facebook settings to maximum and concealed his age.
The files contained photographs from the social networking site, including a number of April which were downloaded just eight days before her murder. There were also pictures of a teenage daughter of one of Bridger's friends and a number of other young girls from the town.
Among the search terms allegedly typed into his computer were "naked young 5-year-old" whilst the computer picture library was found to contain pictures including one of a pregnant 8-year-old girl as well as sexually explicit cartoons.
Bridger insisted throughout that he was not a paedophile, claiming he was impotent as a result of anti-depressants and alcohol abuse - telling the court he drank up to 25 cans of cider and a bottle of wine a day.
He claimed he had been conducting research into his own teenage daughter's physical development, or had been keeping the pictures to complain to publishers after happening across them during a search for SpongeBob Squarepants.
Yet for all his lies and claims that he was out of control on drink and panic, Bridger went to extraordinary lengths to cover his tracks. His cottage had been comprehensively cleaned and a fire was spotted burning evidence away as he calmly walked his dog whilst the rest of the town frantically searched for the missing child.
A blood test taken when he was arrested starkly contradicted his assertion that he had been drinking heavily in the run-up to April's disappearance, while chillingly, it was also to emerge that he had approached three other girls before making off with his victim.
April Jones was described as happy-go-lucky and who, like any child her age, would occasionally play up. She suffered from a mild form of cerebral palsy for which she needed pain-killing medication.
On the day of her disappearance, she had been swimming with her mother and a friend and was allowed to play outside because she had been given a glowing report from school.
The community rallied around the family in the immediate aftermath of her going missing. Four days after she was snatched Machynlleth was a sea of pink ribbons attached to cars, houses and shops in a desperate show of solidarity.
Yet, despite the months of searching which was only reluctantly abandoned in the northern spring, the Jones family do not know what happened to their daughter's remains - a secret that the man who killed her steadfastly refuses to disclose.
