(Above) Roy Terrence Rousseau An eight-month investigation into the murder of Ariel Besley in Caledon last May has now been broadened to include Orangeville and Shelburne, as well as Hamilton, Owen Sound and other areas.

Police say the 18-yearold Brampton man was shot to death. His body was found beside Old School Road on May 15, 2008.

Peel Regional Police arrested Roy Terrence Rousseau, 23, on May 25 during a foot pursuit off Bovaird Dr., Brampton, after he fired at them with the illegally imported gun used to kill Mr. Besley.

The Peel officers returned fire and wounded Mr. Rousseau before arresting him and charging him with seven weaponsrelated offences, including one of possession contrary to a court order, and another of carrying a loaded, prohibited or restricted weapon. He is also charged with possession of property obtained by crime. The circumstances of the 8 a.m. arrest of Mr. Rousseau are being investigated by the Special Investigations Unit.

OPP Constable Sherry Thompson at Bolton had no information with respect to possible charges in connection with Mr. Besley's death. But Peel police said any such charges would be laid by the OPP. "It's their case," said a media relations officer Monday.

Mr. Besley is not believed to be connected in any way to the Shelburne family.
