A girl was stabbed to death after being tortured and raped in a revenge attack by a gang, a court has heard.
Mary-Ann was found dead in Reading's Prospect Park on 7 May
Mary-Ann Leneghan, 16, and an 18-year-old friend were abducted by the gang before her body was found in Reading's Prospect Park in May 2005.
Her friend was shot in the head but survived. Six men deny charges including murder, kidnap and rape.
A new jury has been sworn in after the original jury in the case was discharged by the judge on Monday.
'Torture and kill'
Opening the case prosecutor Richard Latham QC said: "Some were more involved than others, they had various parts, different roles, you have only one trigger on a gun, only one person actually holding the murder weapon, the knife, but we suggest that they all had a role to play and they were acting in concert, as lawyers sometimes say, as part of a joint enterprise to torture and kill these two young women."
Mr Latham told the jury that the likely motive for the girls' ordeal was that Mr Thomas blamed Mary-Ann for a robbery at his flat in April of last year.
Mr Latham said that on the night of 18 or 19 April Thomas was attacked, stabbed and robbed of drugs at the flat on Reading's Oxford Road which he had been renting for a short time.
Mr Latham said: "It is clear that Thomas believed that Mary-Ann and/or (her friend) had set him up for that robbery."
The six defendants are: Adrian Thomas, 20, of Battersea, south London; Llewellyn Adams, 24, of Balham, south London; Indrit Krasniqi, 18, of Chiswick, London; Michael Johnson, 19, of Southfields; and brothers Jamaile and Joshua Morally, 23 and 22, of Balham, south London.
The six men each deny the same nine charges, including one charge of murder, one charge of attempted murder, two counts of kidnap, three counts of rape and two counts of causing GBH with intent.
Jamaile Morally also denies a further charge of raping Mary-Ann.
The hearing continues.
