A man originally accused of the manslaughter of the two sons of a retired Bermuda Police officer and teacher will now stand trial on a double murder charge.

Yuri Fidel Agard is accused of deliberately slaughtering Justin and William Greene outside a Barbados nightclub in March last year after prosecutors decided to upgrade the charges against him.

A preliminary hearing on the case will be heard on Monday, September 3 in District A Magistrates' Court in Bridgetown, followed by a trial before a Supreme Court jury.

The Greene brothers — whose parents are former Bermuda Police narcotics officer Detective Constable Ronald Greene and CedarBridge Academy teacher Margo Greene — died from stab wounds after a dispute with a group of men in the early hours of March 26, 2006.

Agard, of Hutson Alley, Reed Street, St. Michael, Barbados, was charged with the manslaughter of Justin, 21, and William, 25, two days later. The accused was 18 at the time.

Five other men — Jody Omar Farnum, Kelvin A. Squires, Chad Carlton Worrell, Jason Stevenson Hurley and Jamal Marlow Mayers — were charged with violent disorder in connection with the incident and are understood to be awaiting trial.

The Greene brothers lived in St. Joseph's parish in Barbados and are believed to have spent some of their childhood in Bermuda. Det. Con. Greene and Ms Greene divorced in 1992.

Station Sergeant David Welch, from the Royal Barbados Police Force, told The Royal Gazette: "Yuri Agard's charges for the deaths of brothers Justin and William Greene have been upgraded...(to) one count of murder for each of the victims."

He said the decision to amend the charges was taken by the office of the director of public prosecutions.
