ST. JOHN'S, Antigua – A man and a teenager from Antigua were charged Monday in the killing of a British couple on their honeymoon, officials in this Caribbean island said.

Kaniel Martin, 20, and Avie Howell, 17, appeared before a judge in the capital, St. John's, on charges of murder, robbery and receiving stolen property. They were ordered held without bond.

Neither suspect entered a plea to the charges, though the lawyer for Martin later said he would plead innocent.

“All I will say is that my client maintains his innocence,” attorney Ralph Francis said.

Howell's attorney did not immediately return phone calls seeking comment.

Benjamin and Catherine Mullany, both 31 and from Wales, were married on July 12 and went to Antigua for a two-week honeymoon. On July 27 – the day they were to leave – they were shot before dawn at the Cocos Hotel in the island's southwest. Police have said robbery appeared to be a motive.

The slaying of the couple brought unwelcome negative publicity to Antigua and Barbuda, which is economically dependent on tourism. Authorities brought in officers from Scotland Yard to assist the investigation.

Police in Wales said they have informed the families of the slain couple of the latest developments.

“We are pleased at how the investigation is progressing,” the families said in a statement.

Last week, two women linked to the attack were charged with robbery, obstruction of justice and receiving stolen property, namely a cell phone that belonged to the couple.

Police then detained eight other people. Five were released, and three remained in custody: the two men charged Monday and a 31-year-old woman who has not been charged.

Detective Inspector Mike Cranswick of the South Wales Police said investigators are pursuing other leads.
