Alesha MacPhail was just six-years-old when she went to spend the summer with her dad on the idyllic island of Bute, off the coast of Scotland.
The picture book town was surrounded by rollng waves and golden sands. It was such a trustin community that no one locked their doors.
But this little town was rocked to its core on July 2, 2018, when little Alesha was abducted from her her bed by 16-year-old Aaron Campbell.
The teenager raped the little girl and brutally murdered her before dumping her tiny and broken body.
Police were horrified by Alesha's injuries, she had suffered 117 wounds in total, and died alone and terrified.
While she was missing, the whole island came out to search for Alesha - apart from Campbell - and when his DNA was found on her little body, Bute was horrified.
CCTV from Campbell's own mother played a part in pointing the finger of suspicion at the teenager - he was spotted leaving his home several times on the night Alesha went missing.
Chilling Google searches for 'how do police find DNA' convinced officers the 16-year-old was responsible for Alesha's terrible death.
Campbell came up with a bizarre excuse for why his DNA was on Alesha's body, claiming he had been in a relationship with her step-mother, Toni McLachlan, and she had framed him.
He insisted she had planted his DNA at the crime scene from a used condom.
But Campbell had been the one to carry Alesha from her bed in the home she was staying in with her dad.
He carried her down to the shore line and raped her before inflicting what the pathologist described as "catastrophic" injuries.
Psychologist Emma Kenny said: "He wanted to desecrate, violate and destroy her body because he knew he was not going to be able to do it again.
"It's clear from the injuries that Campbell really enjoyed hurting her. They were catastrophic. But what killed her was the pressure he applied to her face and neck.
"The end that she met was something so far outside of what she deserved it's hard to imagine."
Throughout his trial, Campbell insisted he was innocent, forcing Alesha's devastated family to hear about the gruesome acts he had carried out on their beloved daughter.
On March 21 last year Campbell was found guilty of Alesha's murder and sentenced to at least 27 years in prison.
Campbell and Alesha's father, Robert, had fallen out when the teenager complained about the quality of the cannabis he had been sold.
He had contacted Robert on the night of Alesha's murder to buy some drugs and had gone to the house to collect them.
Robert was asleep in bed when Campbell arrived at the home, with the door unlocked as all homes were on the island, and the first room Campbell came to was Alesha's.
While Campbell hadn't gone to the house to abducte, rape and murder the little girl, this was the chance for Campbell to live out a long-held, twisted fantasy.
Campbell had a sick obsession with the online game, Slenderman, about a scary figure who abducts children and kill them.
And a year before Alesha's murder Campbell made a chilling comment to a friend he was chatting to about the online game.
Psychologist Emma Kenny said: "A friend had been watching a documentary that had unnerved her and she told him and his response was 'I might kill one day, just for the life experience'.
"He's not connected he doesn't care about rules or the pain he's caused or about Alesha. What he cares about is enjoyin what he did. His ultimate life goal is to kill someone.
"He caused as much pain as he could. He lived his ghoulish dream and that's what makes him so sinister."
While Campbell will spend the rest of his life behind bars, Alesha's family are trying to rebuild their lives after the horrifying events in March 2018.
Her mum, Georgina Lochrane, has thrown herself tirelessly into charity work.
The Isle of Bute is also struggling to come to terms with the new normal of their lives - Campbell's friends have problems processing what he did.
It will never be the same again.
