The cousin of an honour-killing victim and his friend allowed her to be buried in their garden in Birmingham to win favour with community elders, a court has heard.
Banaz Mahmod, 20, paid the "ultimate penalty" for shaming her family by falling in love with the wrong man, an Old Bailey jury was told.
Her father Mahmod Mahmod and uncle Ari had her strangled to defend a "repugnant" concept of family honour, said Victor Temple QC, prosecuting.
She was found buried in a suitcase in April 2006, five feet under the back garden of a house in Alexandra Road, Handsworth, more than 100 miles away from her home in Mitcham, south-west London.
The jury was told that Ari and Mahmod Mahmod have already been convicted of Banaz's murder and a third man, Mohamad Hama, admitted the charge. Two other men, Mohammed Ali and Omar Hussein, are still wanted for the murder, the court heard.
Banaz's cousin Dashti Babaker and his friend Amir Abbas both lived at the Handsworth address, Mr Temple told the court. He said family and community ties presented an "imperative need to uphold that which they perceive as honour".
"Both these defendants chose to align themselves with and actively assist those who had engineered the murder of Banaz. Such actions would also allow them to ingratiate themselves with both their elders and their contemporaries, knowing that Banaz had been murdered," Mr Temple said.
"They were not only privy to the fact that the suitcase that contained her body was to be buried at the address at which they were resident but they were also complicit in preventing her proper burial."
Babaker, 21, of Redcar Street, Camberwell, south-east London, and Abbas, 31, of no fixed address, both deny perverting the course of justice and a separate count of "preventing the lawful and decent burial of a corpse".
