Scott from Dunfermline in Fife, was a senior director at the credit scoring firm FICO and had travelled to Nairobi for a conference prior to his disappearance.
He was reported missing after failing to meet colleagues to deliver a presentation at the JW Marriott Hotel in the city’s Westlands area.
Scott was known to have visited the Havana nightclub the previous evening.
Kenyan police later said they believed he was taken to a property in the Pipeline district, a slum area, about 9.3 miles (15km) from his hotel.
Prosecutors believe he was held there for a period while attempts were made to extract money from his bank accounts.
His body was later discovered in a pineapple sack with his hands bound in the Makongo Forest.
A post-mortem examination proved “inconclusive,” but pathologists said the injuries on his body were “too minor” to have resulted in his death.
Police initially questioned two men, a taxi driver and a nightclub waiter, believed to be among the last to see him alive.
Two men were later arrested in March last year and one has appeared in court accused of murder.
Officers then launched an appeal to find three further suspects.
