31-year-old Alexander McKellar caused the death of 63-year-old Tony Parsons by hitting him with his car on the A82 near Bridge of Orchy, Argyll and Bute on 29th September 2017.
McKellar, who was originally charged with murdering Mr Parson, pleaded guilty to an amended charge of culpable homicide at the High Court in Glasgow in July.
Detectives launched a major investigation following a tip-off from Alexander McKellar’s ex-fiancée, who left a can of Red Bull at the scene as a marker for the police.
The High Court in Glasgow heard that the body of Mr Parsons would most likely never have been found had it not been for the woman's revelation.
McKellar and his twin brother admitted attempting to defeat the ends of justice.
Robert McKellar was sentenced to five years and three months in jail, while Alexander McKellar was sentenced to 12 years behind bars.
