Road death trial shown CCTV film

Isaac Purcell has admitted driving the car which hit Jack

A witness broke down in tears as a murder trial was shown CCTV footage of a car which knocked down a young boy.

The film showed the child standing on a pavement before a car drove by and a "thump" sound was heard.

Isaac Purcell, 26, has denied the murder of Jack Anderson, 10, along with several other charges.

He is accused of speeding on a number of Edinburgh roads before hitting the boy on Saughton Road North and of failing to stop after the collision.

Mr Purcell is also accused of abandoning his vehicle in a prison car park. He denies all the charges.

The jury was shown footage from a CCTV camera belonging to Russell Hughes, who lives just yards from the pedestrian crossing at which Jack Anderson was killed on 5 October, 2006.

It showed a segment of Saughton Road North just before and to the north of the crossing.

Mr Hughes, 57, broke down as he was taken through the moment when a dark car overtook another vehicle that had stopped at the crossing, just before a thump sound was heard.

It came seconds after a child wearing a shoulder bag was seen walking towards the crossing.

Seconds after the noise, an extended car horn is also heard as the footage shows cars beginning to pull over, with people getting out and gesticulating towards the crossing.

Asked by advocate-depute Alex Prentice QC to describe the footage, Mr Hughes, an electrical contractor, said: "A car stops at the red light and another car overtakes it - going quite fast.

"I hear a thump sound and then a car horn."

The witness wept as he was taken through the footage again.

He was given a five minute break to compose himself.

The witness told the court the footage was from a camera he had installed at his home as a security measure.

Mr Purcell earlier admitted driving the dark green Peugeot 406 which hit and killed Jack, but denies all other charges including driving without insurance and failing to report an accident.

The prosecution has also lodged an alternative charge of causing death by dangerous driving at a Glasgow High Court trial, which Mr Purcell has also denied.

The case continues.
