Murder accused Kevin Warner wanted to clear his name by turning himself in to police and serving as a witness in the Dekimo Martin case, Supreme Court heard.The trial of 21-year-old Mr Warner, which began last Monday, heard from a woman described as the defendant’s “adopted mother” Inez Dill.Ms Dill told the court she received a call from Mr Warner the evening after the murder and while she spoke with him he appeared upset and confused.She said he told her he was the last to see friend Mr Martin alive, but said he left the victim’s home on Peacock Crescent, in Somerset, before the shooting.Ms Dill said: “We sat and we talked and I asked him. He did tell me he was the last to see [the victim] and everyone at that point in time was more or less going against him because he didn’t show his face for the day.“And I said if you haven’t done anything why do you have to go and turn yourself in [to police]. We exchanged words about him being the last to see the deceased and he never elaborated about anything else about committing a crime or anything like that.“He was just upset and wanted to turn himself in as a witness to let them know he had been there.”Mr Warner said people thought he had murdered his friend because he hadn’t been in contact with anyone during that day. Ms Dill said: “He just wanted to clear himself”.Mr Warner is charged with the premeditated murder of 24-year-old Mr Martin on May 28 last year. He is also charged with carrying a firearm used in connection with an indictable offence on the same date.He is represented by lawyers Kim Hollis QC and Elizabeth Christopher and has pleaded not guilty to both counts.The case continues before Puisne Judge Carlisle Greaves this afternoon.
