A pensioner who killed a teenager after reversing over her as she filled up her car at a petrol station has been banned from driving.

Alexander Wotherspoon, 83, was found guilty of causing the death of Eilish Herron at the Asda filling station in Linwood, Renfrewshire, in Septmber 2014.

The 17-year-old was killed after Wotherspoon's Ford Focus reversed into her Renault Clio before knocking her to the ground, reversing over her and dragging her along the concrete for about 20 yards.

Ms Herron, who was a keen netball player and was crowned Renfrewshire's young sportsperson of the year in 2013, was pronounced dead at the scene as a result of a head injury.

Wotherspoon, who has had two hip operations, a knee replacement, uses two sticks to walk and has a shorter right leg as a result of the procedures, was fined £5000 for the offence after being deemed unfit to carry out unpaid work.

He was also banned from driving for five years.

Wotherspoon, of Houston, Renfrewshire, denied causing her death by driving without due care and attention when he went on trial at Paisley Sheriff Court last month.

He did not give evidence but, through defence solicitor Laura Irvine, claimed his knee hit a poorly installed hand lever next to his steering wheel, causing his car to shoot back, resulting in Eilish's death.

Last month, a jury convicted him of careless driving.

Ms Irvine said the former soldier and BT engineer was "utterly sorry" and was a shadow of his former self following Ms Herron's death, which was caused by his "momentary inattention".

She added: "Mr Wotherspoon thinks of it every day and the impact on them.

"He is 83 and finds it difficult to express his emotions. He doesn't sleep and suffers physically and mentally.

"He has no confidence now in making decisions after this - he is a truly broken man. He feels he has let his own family down."

Sheriff Seith Ireland described the death as "a tragic incident" but said a custodial sentence could only be imposed if Wotherspoon's driving was so bad it was close to dangerous driving.

He added: "I begin by saying, in dealing with this case, what the court can do in punishment could not measure or assuage the grief felt by Eilish Herron's family.

"In my view your health precludes you from undertaking unpaid work as part of a community payback order.

"I'm going to make a financial disposal which will require you to pay a fine, which will have some effect on you.

"It will remind you of the effect your driving had on that fateful day, although it can't be taken to be any valuation of the life of Eilish Herron. Her loss is incalculable."

Ms Herron played netball for Paisley Juniors, volunteered as a junior coach and was due to start a nursing degree.

After her death, Netball Scotland created the the Eilish Herron Young Coach of the Year Award, which will continue as a yearly recognition.
