A teenage girl died after falling onto a knife during a struggle with her ex-boyfriend, a court has heard.
Katerina Makunova, 17, was found slumped in a block of flats in Brisbane Street, Camberwell, last July and died from a stab wound.
The teen, from Forest Hill, had been described as a “loving ambitious” girl by her brother.
Oluwaseyi Dada, also of Brisbane Street, pleaded guilty to manslaughter on Wednesday at the Old Bailey.
The court heard the pair had been in a relationship that had recently deteriorated.
In tragic circumstances, the court heard how Ms Makunova fell onto a knife after an altercation began between the pair.
On July 12, Ms Makunova and Dada went onto the lobby of a block of flats where Dada lived. According to police, “a struggle began”.
Police said: “During the course of this altercation both of them fell, but unfortunately Katrina was carrying a knife in her handbag
“Katrina fell onto the handbag, causing the knife to pierce the bag and then stab Katrina in the chest.”
Officers arrived to the scene, at about 12.15pm, and found Dada desperately administering CPR to Ms Makunova.
Despite the efforts of paramedics and Dada, she was pronounced dead at the scene an hour later.
A post mortem examination took place and gave cause of death as a single stab wound.
Detective Inspector Domenica Catino of the Homicide and Major Crime Command, said: “A young woman has lost her life and my thoughts are with her family and friends, who have been devastated by Katrina’s death.
“This is another young person who has been killed as a result of a knife and we need our communities to work with the police to end this scourge.”
Her sister-in-law Shannon Jodie-Leigh Butcher said the whole family were “heartbroken and devastated”.
“I would like her to be remembered as a young, joyful and beautiful girl,” she added. “She was bright, confident, always smiling.
Dada will be sentenced on Tuesday, January 29.
