Becky Watts case: Stepbrother's girlfriend now charged with teen's murder
A man accused of murdering his 16-year-old stepsister from Bristol has been charged with a string of further offences, police said.
Nathan Matthews, 28, is already charged with the murder of Becky Watts and now stands accused of perverting the course of justice, conspiracy to commit false imprisonment and preventing her lawful burial.
His girlfriend, Shauna Hoare, 21, has now also been charged jointly with Matthews with Becky's murder, as well as perverting the course of justice, conspiracy to commit false imprisonment and preventing her lawful burial.
Avon and Somerset Police said the pair have also been charged with possession of a prohibited weapon and four counts of making indecent images of children.
Matthews has also been charged with sexual assault and voyeurism. The alleged sexual offences do not relate to Becky.
The new charges will be added to the indictment at their next court appearance, which is a plea and case management hearing at Bristol Crown Court on August 4.
Becky vanished from her family home in Crown Hill on February 19, sparking a huge search.
Police launched a huge search - including a social media campaign using the hashtag #FindBecky - on February 20 when the student was reported missing.
Her body parts were found by police at a house in Barton Hill, Bristol, on March 2 and detectives charged her stepbrother with murder.
Hoare, of Cotton Mill Lane, Bristol, is still accused of intending to pervert the course of justice by lying to police.
There are no changes to the charges against Karl Demetrius, 29, Donovan Demetrius, 29, Jaydene Parsons, 23, and James Ireland, 23, who are all accused of helping dispose of and conceal Becky's body parts.
Detective Superintendent Liz Tunks said: "Our thoughts and sympathies are with Becky's family.
"This has been a very difficult time for them and they have had to endure yet more pain as we have worked to understand the full circumstances surrounding her death.
"Our continuing investigative work in this case demonstrates our determination to explore all avenues even after suspects have been charged.
"This has been a meticulous and exhaustive investigation.
"We are determined to find answers for Becky's family and bring all those who played a part in her death to justice.
"I would like to thank the local communities in St George and Barton Hill for their patience and co-operation as this investigation continues."
Rachael Scott, head of the Crown Prosecution Service's south west complex casework unit, added: "Following receipt of a full file from Avon and Somerset Police, the CPS has authorised a number of additional charges against both Nathan Matthews and Shauna Hoare.
"Most significantly there is now sufficient evidence to charge Shauna Hoare with the murder of Becky Watts.
"Proceedings are now ongoing and the defendants have the right to a fair trial. It is very important that there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings."
