A pensioner killed a teenage girl after reversing over her as she filled up her car with petrol.

Alexander Wotherspoon was convicted of killing 17-year-old Eilish Herron at the Asda filling station in Linwood, Renfrewshire, on September 10, 2014.

Paisley Sheriff Court heard how Ms Herron was "swept away" by the 83-year-old's Ford Focus as it reversed back, crashing into her car and then knocking her to the ground.

Wotherspoon admitted hitting Ms Herron, causing her to die from a head injury, while behind the wheel of his silver Ford Focus.

He had denied he caused her death by driving without due care and attention, in breach of Section 2B of the Road Traffic Act 1988, and went on trial at Paisley Sheriff Court.

The court heard paramedics had to use two car jacks to lift up Whetherspoon's vehicle to get to Ms Herron.

She was pronounced dead at the scene as a result of a head injury she suffered after being dragged about 20 yards while trapped under Wotherspoon's vehicle.

Wotherspoon did not give evidence at his trial but claimed through defence solicitor Laura Irvine that his knee had hit a poorly installed hand lever next to his steering wheel, causing his car to shoot back and hit Ms Herron, who was filling her blue Renault Clio up with petrol.

A jury took just an hour to reject his version of events and find him guilty of failing to keep control of his car and, while it was reversing, hitting Eilish's car, knocking her to the ground, moving her car out of the way, reversing over her, dragging her underneath the car and causing her to be so severely injured that she died.

Wotherspoon showed no emotion as he was convicted and Sheriff Seith Ireland adjourned the case for the pensioner to be assessed by social workers ahead of sentencing.

He also banned Wotherspoon from driving, saying the case involved "a very serious charge" and was "a matter of great anxiety" for the jury.

Wotherspoon, of Houston in Renfrewshire, will learn his fate next month.

Speaking outside court after the verdict, Eilish's mother Shannel Herron said Wotherspoon had shown no remorse.

She said: "All I ever wanted was for him to put his hands up and admit his guilt and say sorry.

When he pleaded not guilty we, as a family, and Paisley, as a community, were totally shocked - we couldn't understand what his defence was going to be.

"He's blamed the faulty equipment but he said in his police interview that there was nothing behind him - Eilish was behind him, she was filling her car up with petrol.

"It really and truly beggars belief. He has shown no remorse.

"He actually stepped over Eilish, my daughter's body, to get out of his car, and said he was not guilty. He doesn't have a conscience."
