The son of murdered doctor Victoria Anyetei has told of his anger after seeing her lifeless body slumped in the driver's seat of her car outside their Dartford home.

Andrew Thompson said he had been alerted by his friend David Quartey, who is accused of the frenzied attack in which the 54-year-old consultant paediatrician was stabbed 56 times.

Quartey, 22, lived in his guardian Dr Anyetei’s house in Teynham Road, along with her son.

Giving evidence at Maidstone Crown Court, Mr Thompson, a law student at Kent University in Canterbury, said on the morning of August 14 last year, his mother woke him as usual after 6am for breakfast.

He went back to bed at about 7am. He recalled later that his mother afterwards went to his room.

"She said: 'David is scaring me. He is acting strange.' I remember opening my eyes for the last couple of words. She didn’t explain."

Mr Thompson said Quartey went to his bedroom at about 10am. He noticed Quartey had "some stuff" on his chin, which he thought was feather from his pillow.

"He went downstairs," he continued. "The next thing I knew I heard ‘Andy, Andy’. I looked out of my bedroom window.

"I could see my mother in the front seat. David was in the passenger seat. He is getting hold of her. He is shaking her. I got dressed and ran downstairs.

"I could see my mum sitting there still. I grabbed my mother and started shaking her. I noticed a stab wound to the right side of her ribs.

"I didn’t see any signs of life, but I was hoping. I was screaming and shouting. I phoned 999. I was feeling very angry - fuming.

"I went to a neighbour’s house in Watling Street. David was with me. He was sitting on the sofa and was in shock. He was shaking and shivering."

Quartey, now of Humber Road, Dartford, denies murder.

The trial continues.
