An investigative computer analyst from Queensland Police has given evidence at the trial of Robert Crawford.
Prosecutors have alleged Mr Crawford's phone was unlocked multiple times during hours when he initially told police he was asleep.
The prosecution has now closed its case and the defence will call expert witnesses in when the trial continues next week.
A former Queensland RAAF pilot accused of killing his wife, allegedly "interacted" with his phone during the time he told investigators he was sleeping and she accidentally died, a jury has heard.
Robert Crawford is on trial in Brisbane charged over the murder of 49-year-old Frances Crawford in Upper Lockyer in July 2024.
The 49-year-old has pleaded not guilty, and maintains his wife died in a tragic accident.
A Supreme Court jury has already heard Mr Crawford called Triple Zero (000) in the early hours to report he found Ms Crawford trapped underneath their ride on lawnmower at the bottom of a retaining wall.
He told officers he had been asleep at the time when he believed his wife was fatally injured trying to move the machine away from sprinklers, the jury has heard.
On the final day of prosecution evidence, an investigative computer analyst from the Queensland Police Service took the witness stand.
