A motorist who killed a Haringey woman after following his sat nav and driving the wrong way down a dual carriageway has been jailed.

Samah Suliman, 31, of Richmond Road in Tottenham, was killed two days before her engagement party when her car was hit by a driver coming the wrong way down the A413 at Gerrards Cross.

David Pulsford, of Longmoor Avenue in Barnet, pleaded guilty to causing death by dangerous driving and was jailed for 15 months at Aylesbury Crown Court last Thursday.

Pulsford was following instructions from a sat-nav that told him to turn the wrong way onto a dual carriageway, despite passing two signs telling him to turn left onto the bypass on July 25 last year.

His Vauxhall Astra then hit Miss Suliman’s Saab head-on. She was pulled from the wreckage and was given mouth-to-mouth by her sister, who was travelling in a car behind her, but she died at the scene.

The sisters were just a mile from their house where they were going to visit a sick uncle.

Miss Suliman’s mother, Hayat Abdalla described her daughter, known as Sam, as the “glue” of the family and her best friend.

In an emotional tribute she added: “Sam was a bright, intelligent, funny lively girl. She worked hard and always excelled in everything she did and we were all very proud of her.

“Sam was beautiful in all ways. She was made of kindness, love and generosity. Her life was full of laughter. She was a bright, thoughtful and kind daughter, sister, fiancé, friend and colleague.”

Miss Suliman’s engagement party was due to take place two days after her death but instead the hired marquee was used for her funeral.

Mrs Abdalla added: “Her tragic death two days before her engagement has truly brought our family to a stand still and we are all trying to slowly move on, but can’t. Her tragic loss at a young age has shocked us all and we still can’t believe it.”

By fundraising in Miss Suliman’s memory her family have donated £5,000 to help rebuild Khartoum Village in Sudan.

Pulsford was sentenced to 15 months in jail by Judge Christopher Tyrer last week.

Speaking after the sentencing, Sergeant Dominic Mahon, of the Thames Valley Police roads policing department, warned against the danger of sat navs.

He said: “Satellite navigation systems can be a useful aid to drivers but they can also be a dangerous distraction.

“Mr Pulsford misunderstood his sat nav’s instructions and ignored the road signs that should have made him realise his error.

“If Mr Pulsford had been concentrating fully on his driving, this devastating incident could have been avoided and the Suliman family would not have lost their beloved Samah.”
