A mother was stabbed to death on a Sheffield street by her ex-partner who feared he would lose custody of their two-year-old son, a court heard.
Erhan Mehmedov, aged 45, told his mother the night before the killing in Blackstock Road, Gleadless Valley, that he was going to stab Dimitrina Borisova to death.
He attacked Dimitrina as she waited for his mother to hand over the child in February.
Dimitrina, a 46-year-old accountant originally from Bulgaria, died from 17 stab wounds including three to her chest, at least one of which pierced her heart.
Mehmedov, a Turkish national, was arrested at a bus stop and is said to have told police: “I did it, I will tell you everything.”
Graham Reeds QC, prosecuting, told Sheffield Crown Court: “The defendant started to think he would lose custody of his son to her, and he couldn’t bear the prospect that she would beat him in the court process. He decided he was going to do something about it. It was a controlled, deliberate and relentless attack, carried out with an obvious intention to kill her.”
The attack was seen by several eye-witnesses, including a 10-year-old girl who gave evidence to the jury by videolink.
Memedov, of Blackstock Road, admits manslaughter but denies murder, claiming he lost his self-control following taunting from Dimitrina.
The trial continues.
