Becky Watts stepbrother and his girlfriend guilty of killing11 November 2015
Becky's body was dismembered at the home of Nathan Matthews and Shauna Hoare
The stepbrother of Becky Watts has been found guilty of murdering her during a sexually motivated kidnap plot.
Nathan Matthews, 28, had admitted killing and dismembering the teenager, but claimed he was only trying to scare her to teach her a lesson.
But a jury at Bristol Crown Court found him and his girlfriend Shauna Hoare guilty of conspiring to kidnap her, partly for sexual reasons.
Hoare, 21, was cleared of murder but found guilty of manslaughter.
'Sexually motivated kidnap'
She was also convicted of perverting the course of justice by lying to police and preventing a lawful burial by dismembering and hiding Becky's body - charges Matthews had admitted.
The jury took just over three hours to convict the couple, after hearing 21 days of evidence.
As the first verdict was returned, related to kidnap, people in the public gallery began clapping and shouting "yes".
Becky's father Darren and his wife Anjie sobbed, while Matthews and Hoare remained totally emotionless.

Matthews, who gave his address as Hazelbury Drive in Warmley, South Gloucestershire, suffocated Becky at her home in Crown Hill, Bristol, on 19 February.
He then dragged her body into the boot of his car and drove it to the home he shared with his girlfriend less than two miles away in Cotton Mill Lane.
In the days that followed, Matthews bought a circular power saw, goggles, masks, bags, cling film and tape to cut up and package Becky's body.

Police initially interviewed the couple as witnesses, after they told officers they had been at Becky's home that day to help her stepmother, Matthews's mother, for whom Hoare was a registered carer.
But when they knew police would be coming to the house, on 24 February, they made arrangements to move Becky's remains to a shed at a friend's address, 80 metres away.
Hoare denied any knowledge of Becky's death and subsequent dismemberment, but the prosecution said the idea she could have been in "blissful ignorance" of events, while being with Matthews the morning of Becky's death, and throughout the days her body was dismembered, was "ridiculous".
'Sinister motive'
Speaking outside court, Detective Superintendent Mike Courtier, said their "macabre plan" had resulted in Becky's killing.
"Matthews and Hoare concocted a heinous plan to kidnap his stepsister Becky for reasons that they have failed to fully disclose, other than she occasionally left items on the floor which could have tripped up Nathan Matthews' mother.
"The body of evidence however suggested a more sinister motive related to their deep-seated hatred for Becky and their twisted sexual desires."
"They took her body back to their home in Cotton Mill Lane and began the horrific and grotesque task of dismembering her over a matter of days.
"It is virtually impossible to comprehend this level of depravity."
Becky's father Darren and his wife Anjie, who is Matthews's mother, described her as a "big-hearted" girl who was "full of life".
