Two men charged in the slaying of a British couple in Antigua last year must stand trial in a separate killing on the Caribbean island, a judge ruled Tuesday.

Kaniel Martin and Avie Howell stand accused of killing the honeymooning couple from Britain in their vacation cottage in July.

But authorities have also charged Martin and Howell with killing three other people last summer in separate incidents. Chief Magistrate Ivan Walters ruled that there is enough evidence to try the men in one of those cases.

The court has yet to rule on whether they should be tried in the other killings, including that of Catherine and Benjamin Mullany of Wales. The dawn attack on the newlyweds prompted calls for a crackdown on violent crime in Antigua.
