A murder accused yesterday dismissed evidence against him as lies.

Khyri Smith-Williams claimed testimony from Troy Harris was fabricated.

He told Supreme Court: “This guy made up the whole fiction story in his head.”

Mr Smith-Williams is charged with the killing of father of one Colford Ferguson.

Mr Ferguson was murdered as he worked on a house at the junction of Mangrove Bay Road and East Shore Road in Somerset in February 2011.

Mr Harris earlier told the court that Mr Smith-Williams had confessed to him his involvement in the killing. He said that Mr Smith-Williams had said another man, Rasheed Mohammad, had pulled the trigger and that the wrong man had been killed.

Mr Harris said that he had two conversations with Mr Smith-Williams about the murder — one in Westgate Correctional Facility and the other at the defendant’s home when the two had been drinking.

Mr Smith-Williams, 27, said yesterday that the two had been in prison at the same time.

He told Jerome Lynch QC, his defence counsel, that the subject of Mr Ferguson’s murder had never come up. Mr Lynch said that in Mr Harris’s testimony he had said that he and Mr Smith-Williams had smoked marijuana together while in prison.

Mr Smith-Williams said: “I never smoked weed in Westgate. Weed’s not my thing.”

He added that he had been tested for drug use while in Westgate and had never failed.

The defendant also denied he had ever discussed Mr Mohammad with Mr Harris.

Mr Smith-Williams admitted that Mr Harris had visited his home in Somerset, but denied that he got drunk in the presence of the witness.

He is charged with premeditated murder and the use of a firearm to commit an indictable offence.

He denies both charges.

Mr Lynch asked his client to “cast his mind back” to the day Mr Ferguson was murdered.

He asked: “Can you recall what you were doing?”

Mr Smith-Williams said that he could not.

He added: “My birthday was five days before that incident. I don’t even remember what I was doing on my birthday.”

Mr Smith-Williams said that he had heard Mr Harris had a “vendetta against Somerset guys” since he was shot in November 2015. He added: “There were rumours going around here that he was going to bring down everybody in Somerset.”

Leroy Mathurin, a police officer, said earlier yesterday that Mr Harris was not forced or offered anything in return for evidence against Mr Smith-Williams.

His testimony backed evidence from police detective Michael Redfern on Thursday.

Mr Mathurin said that he — like Mr Redfern — had been involved in the case since June 2016.

He added that the pair had travelled to the UK to speak to Mr Harris about the 2012 murder of wheelchair-bound Lorenzo Stovell in Sandys.

Mr Mathurin said that Mr Harris said he also wanted to give police information on another case.

He added the two officers spoke to Mr Harris about the murder of Mr Ferguson in another interview later the same day.

Mr Mathurin said: “The only thing he mentioned was the welfare of his family.”

He added that Mr Harris did not ask the officers to return for a third interview to discuss the Ferguson case.

But Mr Mathurin said he and Mr Redfern had visited Mr Harris again to “put the specifics” of the case to him.

The trial continues.
