The timeline of events surrounding the murder of Brian Low near Aberfeldy has been the subject of much scrutiny.
Mr Low, 65, was shot dead as he walked his dog Millie in the Pitilie area close to the Perthshire town.
A murder investigation was launched by police, but only after his death was initially treated as non-suspicious.
We take a chronological look at what has happened in the case so far.
Saturday February 17: Brian Low dies
Mr Low was walking on a remote dirt track close to his home in the Pitilie area with black Labrador Millie when was found dead at around 8.30am.
It has not been confirmed who raised the alarm, but an ambulance was called to the scene at 8.34am.
At this stage, police treated his death as medical-related due to the way his body “presented” at the scene.
Wednesday February 21: Medical examination of body
A medical examination took place on Mr Low’s body, with the death still being treated as non-suspicious at that stage.
It has not been confirmed who oversaw this examination or why it only happened four days after the death.
This examination established that Mr Low had injuries “consistent with being fatally shot”, escalating the case to a potential suspicious death.

Given what was discovered during the medical examination, police established a “scene” at the remote dirt track where he died, while they awaited official confirmation of how Mr Low died.
Friday February 23: Post-mortem confirms shooting
A post-mortem was held to establish a cause of death.
This involved two pathologists – which is required where criminal prosecution is likely in a case to ensure evidence is corroborated.
A post-mortem normally takes place in a mortuary examination room which is similar to a hospital environment.
The pathologists involved in Mr Low’s post-mortem confirmed on Friday evening that he had been shot by a third party.
A murder investigation was launched “immediately”.
