Murdered accused Jordan Johnstone was caught on CCTV at a Dundee filling station on the morning that his sister Annalise was killed.
The 25-year-old was filmed driving a Ford Galaxy people carrier to BP’s Kingsway branch at 12.15am on May 10.
The High Court in Livingston previously heard that Annalise was found dead – after her throat was cut from “ear to ear” – later that day.
Jurors were played CCTV footage that showed Johnstone parking Newlands’ Ford Galaxy beside a fuel pump and walking into the shop.
The front passenger door of the vehicle is seen opening and closing twice, but no one else gets out of the car.
In a statement to police, Johnstone had said he drove Annalise to their uncle’s home in Auchterarder, where she thought she could get drugs.
Detective Constable Keith Stockton told the high court that he was tasked with gathering CCTV footage from key inquiry locations.
Film from around 100 cameras was analysed as part of the investigation.
“We carried out a trawl of CCTV across the area,” he said. “That involved police driving and walking along routes looking out for any cameras at private homes and businesses.”
In the footage captured at the BP station, Johnstone is wearing a dark grey T-shirt and dark trousers.
The trial before Lady Smith continues.
