Tulay's father allegedly disapproved of her relationship with Halil Unal
The mother of an alleged "honour killing" victim has denied that it was she who killed her daughter.
Hanim Goren was giving evidence against her husband Mehmet who is accused of schoolgirl Tulay Goren's murder.
Mehmet Goren, 49, denies murdering Tulay, who went missing from Woodford Green, north London, in 1999 aged 15.
The teenager had previously run off to live with Halil Unal, who was then 30, before being brought home by her parents, the court has heard.
Michael Turner QC, defending Mehmet Goren, suggested to Mrs Goren that she was more upset than her husband about the situation.
But Mrs Goren said: "As a mother I was angry, I was upset. I did not kill her.
"The person who killed her is over there," she said, as she gestured to her husband in the dock.
Mrs Goren, who is appearing for the prosecution, previously said Mr Goren tied up his daughter at their London home on 6 January 1999, a day before she disappeared.
She said her husband disapproved of the relationship Tulay was having with Mr Unal, due to religious differences and the age difference.
The court heard that in March 1999 Mrs Goren was arrested on suspicion of perverting the course of justice and murder.
She was released without charge and she asked to speak to the police again one month later.
Mr Goren and Tulay's uncles Cuma Goren, 42, from Walthamstow, east London, and Ali Goren, 55, from Walthamstow, deny murdering Tulay on 7 January 1999.
Mehmet Goren and his brothers also deny conspiring to murder Mr Unal between May 1998 and February 1999.
The trial continues.
