Couple guilty of murdering nanny

Victim’s mother called the convicted pair ‘monsters’

AFrench couple was yesterday found guilty of murdering their 21-year-old au pair and then burning her body on a bonfire in their London garden in September last year.

Sabrina Kouider, 35, broke into tears after she and partner Ouissem Medouni, 40, were found guilty by a jury at London’s Old Bailey court of murdering French live-in nanny Sophie Lionnet.

“Only Kouider and Medouni know exactly how they killed Sophie but the prosecution was able to prove that she died as a result of purposeful and sustained violence, and not by accident,” said state prosecutor Aisling Hosein.

“They were both jointly involved and came up with a plan to try and destroy her body and escape responsibility for this horrendous crime,” she added.

Majority decision

The jurors deliberated for a week before unanimously convicting Kouider and ruling by a majority decision of 10 to 2 that her partner Medouni was guilty.

Fashion designer Kouider is to undergo psychiatric assessment before sentencing, which is due to take place on June 26. Both denied murdering Lionnet, from Troyes in eastern France, although they had admitted during the twomonth trial to burning her body.

The court heard how the couple had interrogated and tortured Lionnet over their belief she was conspiring with one of Kouider’s former boyfriends — Mark Walton, a former member of Irish band Boyzone — who they claimed sexually abused members of their family. Kouider, who has two children, told London’s Old Bailey court that she hit the au pair “really bad” with an electrical cable.

The victim’s mother called the guilty pair “monsters” in a statement read to court.

‘Reserved young girl’

Catherine Devallonne said she “fell into shock and was hospitalised” after police broke the news that her daughter, whom she described as a “reserved young girl”, had been killed.

“I’ve been living this nightmare ever since,” she added, explaining that the victim’s brother was suffering from “mental trauma”, and had been placed with a foster family.”

Police described how the victim was subjected to a “series of ‘interrogations’ ... over a 12-day period, in a bid to force Sophie to confess to various false crimes they had accused her of.”
