 According to Ken Barrett, who was involved in the murder of Finucane, Spence had made the initial suggestion to him that Finucane should be killed.Spence introduced Barrett to an officer from Special Branch with whom the B Company commander had been in regular contact, and from this man Barrett received the information that Finucane was organising the IRA's finances.Michael Stone claims in his book "None Shall Divide Us" that Finucane was killed because he overheard a conversation in the Maze prison between Stone and Special Branch in which Stone stated that if he was given more than 30 years for the Milltown attack then he would say that he colluded with the RUC in the operation, and that the white van containing RUC officers watching the cemetery was actually his getaway vehicle.
