Four people will go on trial in connection with the murder of teenager Becky Watts.
Becky, 16, vanished from her family home in Crown Hill, Bristol, on February 19 and was reported missing the following day.
Police launched a huge search, which led to Becky's body parts being discovered at a house in Barton Hill, Bristol, on March 2.
Becky's stepbrother, Nathan Matthews, 28, was later charged with her murder alongside his girlfriend Shauna Hoare, 21.
The couple were also charged with perverting the course of justice, conspiracy to commit false imprisonment, preventing Becky's lawful burial and possessing a prohibited weapon.
Donovan Demetrius, 29, and James Ireland, 23, were charged with assisting an offender.
The process to select a jury to hear the case is expected to begin at Bristol Crown Court.
The trial, which is likely to last up to five weeks, is being presided over by Mr Justice Dingemans.
When they last appeared in court, Matthews, of Hazelbury Drive, Warmley, South Gloucestershire; Hoare, of Cotton Mill Lane, Bristol; and Ireland, 23, of Richmond Villas, Avonmouth, were remanded in custody.
Demetrius, of Marsh Lane, Redfield, Bristol, was released on conditional bail.
