Two men charged with the murders of British honeymooners Ben and Catherine Mullany in Antigua appeared in court Monday.
Kaniel Martin, 22, and Avie Howell, 18, were remanded in custody by a magistrate on the Caribbean island.
They are next due to appear on March 25.
The two men are also facing three other murder charges, it was revealed over the weekend.
A Scotland Yard forensics team, which was sent to help the troubled Antiguan force after the killings last summer, found evidence linking the Mullany murders with three unsolved cases.
The pair have now been charged with the murders of two local men and a woman — Tony Louisa, Rafique Kareem Harris and Juanita Anderson Walker on June 18, July 12 and August 8, 2008.
The Mullanys, from South Wales, were on the final day of their honeymoon when they were the victims of a violent attack at the Cocos Hotel And Resort on July 27.
Mullany, 31, a doctor, died instantly in what is believed to have been a botched robbery at their isolated cottage at the beachside resort.
Her husband, a trainee physiotherapist who was also 31, died in the hospital in Swansea after being flown home while in a coma.
The men will stand trial over the murders of the British honeymooners later this year.
