A mother has been found guilty of the manslaughter of her teenage daughter's 21-year-old boyfriend.
The Old Bailey heard that Gedu Bibi, 47, of Walthamstow, east London, disapproved of Sumon Miah's relationship with her daughter, 13.
The jury heard Bibi lured him to her house in October 2006 after she was incensed when she saw topless photos of her daughter on his phone.
Mr Miah was then hit on the head with a chair leg. He died nine days later.
Bibi was also found guilty of perverting the course of justice after she told her daughter Shuhina Khanam to tell police that he had come at her with a knife, and she hit him to defend herself.
Her younger brother Fhalak, then 12, was told to back up the story, the court heard.
Although there were discrepancies in the two children's accounts, police had no witnesses to contradict what they said.
The court also heard that family members had claimed that Mr Miah had made abusive phone calls to Shuhina and left her too scared to go to school.
Bibi's former lover, Lilu Miah, 48, who was charged with murder and manslaughter in relation to the case, was cleared of these charges at the Old Bailey.
The case remained inactive until 2010 when a family friend of Lilu Miah - Monor Uddin - came forward with information.
In a victim impact statement, Sumon Miah's brother Kawsar said: "What we have gone through is so unbelievably painful.
"The suffering never stops and you never stop thinking what could have been."
Describing the victim's mother, he said: "She lost all faith in humans. Sometimes I have heard her crying in the early hours of the morning, which is difficult because there's nothing I can say or do to comfort her."
Bibi and Miah will be sentenced at a date to be fixed.
