Brit honeymoon couple killer stabs inmate

Kaniel Martin was one of two men convicted in July of the killing of Welsh newlyweds Benjamin and Catherine Mullany on the holiday isle of Antigua, and was sentenced last month.

Senior Sergeant William Holder, of the Royal Police Force of Antigua and Barbuda, said: “There was an incident in prison on Friday. Investigations are going on.

“At about 6.30am an inmate was stabbed by Kaniel Martin. It’s a serious offence.”

He said Martin used a “sharp implement” and the 21-year-old victim was treated in hospital for “serious but not life-threatening” injuries. Snr Sgt Holder would not comment on the charges Martin, 24, could face.

Mr Mullany, a former South Yorkshire Police officer, and his wife, both 31, were gunned down in Antigua in July 2008, two weeks after they had tied the knot.

Martin and Avie Howell burst into the couple’s beachside hotel chalet at dawn and shot them both in the head – making off with a digital camera, mobile phone and a small quantity of cash.

Less than a fortnight later, the pair killed shopkeeper Woneta Anderson in almost identical circumstances.
