THE father of teenager Alex Shoulder who was killed by a drink driver, paid tribute to his son by laying flowers at the scene of the tragedy.

A solitary bunch of red roses is tied to the lamppost in Totteridge Road, High Wycombe, with a touching message saying 'Alex, missing you mate, always and forever, love dad'.

The tribute comes within days of 21-year-old Ghazanfar Mahmood pleading guilty to causing death by dangerous driving of the 19-year-old after his car careered out of control and mounted a pavement when he was twice over the drink drive limit. An alternative charge of causing death by careless driving while under the influence of alcohol was dropped by the Crown Prosecution Service.

Alex's father, Tony, said: "Alex gave a lot in life and in death too because he was an organ donor. He has made me a richer person and will be missed by so many people."

Mr Shoulder made the trip from the family's home in Billericay, Essex, to watch Mahmood admit causing death by dangerous driving at Reading Crown Court last Wednesday.

The court heard how Mahmood, lost control of the Vauxhall Cavalier he was driving as he tried to negotiate a corner in Totteridge Road, High Wycombe, on January 18.

Buckinghamshire Chilterns University College student Alex was left unconscious in the road after he was struck by the car when walking back from his part-time job which he had to help him through his time at college.

He died in the intensive care unit of Wycombe Hospital the following day.

The teenage victim was in his second year studying for a degree in media with film and video at the college.

Mahmood, of Roberts Road, High Wycombe, was immediately suspended from driving at Reading Crown Court on Wednesday.

Judge Jonathan Playford warned Mahmood that he faced a spell behind bars.

Ben Gumpert, prosecuting, said the fact that Mahmood was twice over the drink drive limit when the accident happened was included in the more serious charge which had been admitted by Mahmood.

Paul Wakeley, mitigating, told the court Mahmood had never been in trouble with the police before and did not have any penalty points on his driving licence.

Mahmood was released on bail for sentence at Reading Crown Court on July 20.
