Timeline of killing at beauty spot

• 1.58am: Callum Davidson is seen on Kirrie town centre CCTV cycling at a “leisurely pace”. Mr Donaldson’s blood was on the handle grips of his mountain bike.

• June 7 4.50am: RSPB warden Victoria Turnbull and colleagues arrive for a bird survey at Loch of Kinnordy. The charred and dismembered body of Mr Donaldson lies beside his burned out car. A post-mortem examination reveals the cause of death to be deep chopping wounds around the base of his neck, which twice severed his spinal cord. Pathologists record 26 stab wounds on his body.

• June 7 8am. Tasmin Glass turns up as normal for work at Lee’s café and takeaway on Reform Street, Kirriemuir. Among her customers that day are police officers drafted in from other parts of Scotland as part of the major investigation. Later that day she attends her regular weekly singing lesson in Blairgowrie. • June 7 early evening: Dickie, Davidson and Claire Ogston go for tea at the Airlie Arms Hotel in Kirriemuir, having already agreed to “stick to a story” about their movements the previous night.

• June 8: Davidson gives his first witness statement to police, telling them he and Dickie were at home, drinking beer and watching television during the time Steven Donaldson is alleged to have been murdered.

• June 14: Dickie, Davidson and Glass are all arrested for the murder of Steven Donaldson. The trio are charged at Bell Street police headquarters in Dundee in the early hours of the following morning.

• April 1 2019: The trial of Steven Dickie, Callum Davidson and Tasmin Glass begins at the High Court in Edinburgh, before Lord Pentland and a jury of eight men and seven women. • April 23 2019: After 14 days of evidence, advocate depute Ashley Edwards QC closes the Crown case. One of the charges against Dickie and Davidson alleging abuse of a kitten is dropped, and the prosecutor also makes an alteration to the murder indictment. All three accused subsequently take the stand to give evidence on their own behalf.

• At the conclusion of defence evidence, the Crown drops five other charges on the indictment, leaving all three accused facing only the single charge of murdering Steven Donaldson.

• May 2 : The jury of eight women and seven men retire to consider their verdicts.

• May 3 : After nine hours of deliberation, they find all three guilty of killing Mr Donaldson. Davidson and Dickie are found guilty of murder. Glass is guilty of culpable homicide.
