MURDER OF STEVEN DONALDSON:

• June 18 2017: Steven Donaldson is introduced to Tasmin Glass at Fife’s Knockhill race track. A shared love of motorcycles would lead to romance.

• End of 2017/early 2018: Cracks appear in the relationship and Glass writes off a car bought for her by Mr Donaldson, triggering a dispute over insurance money.

• June 6 2018 early evening: Glass, by then in a sexual relationship with Steven Dickie, goes swimming with Callum Davidson and his girlfriend Claire Ogston in the River South Esk at Cortachy.

• June 6 9.30–11pm: Glass’s distinctive orange Vauxhall Corsa is filmed by CCTV on various Kirriemuir streets, with Davidson in the front passenger seat. They visit Davidson’s uncle, where a baseball bat is collected, before the car is seen by two witnesses in the car park at Kirriemuir’s Peter Pan playpark on the Hill.

• June 6 just after 11pm: Steven Donaldson arrives in his BMW at the Hill, where Callum Davidson punches him several times. He is pushed aside by Steven Dickie, who launches a frenzied attack with a knife. They drive their victim on rural roads around the north of Kirriemuir in his car, before arriving at the Loch of Kinnordy RSPB reserve car park west of the town.

• Steven Donaldson tries to flee his killers, but is battered at the entrance to the reserve before being dragged back through the car park and placed under the front nearside corner of his car, which is then set alight. His killers walk back to their home town.

• June 7 00.49am: Two figures are seen emerging from the area of Kirrie Den and crossing the road towards the town health centre.
