Popular Georgia Williams had many friends including Jamie Reynolds, who was 22 when he betrayed his pal's trust in the worst way possible.
For when the A level student agreed to Reynolds' request, she had no idea he had harboured a fascination for hanging, strangulation and necrophilia since he was a teenager.
By the time the twisted killer ended her life, he had already amassed 16,800 images and 72 videos of sexual violence as well as writing 40 stories about committing fatal attacks on girls, drawing nooses on copies of their Facebook photos.
Reynolds, from Telford in Shropshire, carried out his sick fantasy for real in 2013 after coming up with a ruse to ask Georgia to help realise his dreams of becoming a photographer.

The teenager agreed to an "artistic photoshoot" involving a "simulation hanging", with Reynolds falsely assuring her in a message on social media: "You would be standing on a box. I would edit that out on the computer so it would look like you were floating."
Two days later, following a Crimewatch appeal, Georgia's body was found in woodland near Ruthin, in north Wales. It later transpired that Reynolds had written a story called Georgia Williams in Surprise which detailed exactly what he had intended.
Police found the last photos of Georgia alive on Reynolds' hard drive, showing her smiling and posing with a red rope around her neck. In the next series of images, she is dead.
Reynolds became one of the youngest in British criminal history to be sentenced to a whole life term in prison. And as her family came to terms with the loss of their loved one, they were horrified to learn he had carried out a near-identical attack on a teenager five years before.
Officers had previously been given evidence of his obsession with images of women being hanged but let him off with a warning. Reynolds had gone onto ram a colleague's car after she spurned his advances, with police writing it up as a traffic accident.
Georgia's parents went onto fund the The Georgia Williams Trust, which funds sports, music and outdoor adventures for young people. "We still have nightmares," the student's mum Lynnette told The Mirror in 2023.
"One of us will wake the other up at night screaming. We help each other through them. I relive the day as soon as I wake up or when I try to sleep. I feel drained most of the time, it’s on your mind constantly. It never goes away."
The murderer's whole-life sentence means he will die behind bars, with the judge at Stafford Crown Court calling him a "serial killer in the making".
