Couple found guilty of murdering their nanny

A south London couple were today convicted of the murder of their nanny at the Old Bailey.

Sabrina Kouider, 35, and Ouissem Medouni, 40, were both found guilty after a three-month trial of murdering Sophie Lionnet from Troyes, France, on or before Wednesday 20 September, 2017, at the house where they lived with their two children in Wandsworth Park Rd SW18.

The couple, who were both French nationals like 21-year-old Sophie, had previously pleaded guilty on 12 January at the same court to perverting the course of justice by way of preventing a lawful burial of her body.

Medouni, a self-employed businessman and Kouider, a self-styled fashion designer/stylist who liked to boast of mixing with celebrities, will be sentenced on Tuesday, 26 June.

Detective Inspector Domenica Catino, of the Met’s Homicide and Major Crime Command, (HMCC), said: “As the investigating officer in this case I am satisfied that the verdict has bought some justice for Sophie but of course it will never bring her back.

“I cannot imagine what thoughts were going through Sophie’s mind whilst being held a prisoner in those 12 days leading up to her death but from the harrowing images obtained it showed a scared, broken and emaciated young girl who probably knew she was shortly facing death.

“I believe that we are Sophie’s voice telling of the torment, abuse and torture she suffered and today she has finally been heard.

“This has been an extremely harrowing and tragic case. Both Ouissem Medouni and Sabrina Kouider have robbed Sophie Lionnet, who was only 21, of her promising life and took her from her family and friends, who will never again get to see a beloved daughter, sister and friend.”

The pair attempted to destroy the victim’s corpse through use of caustic acid.
