RCMP say Duncan Laird, 27, of no fixed address, was wanted on several counts of possession of stolen property and also on arrest warrants from numerous charges out of Killam, Alta.
On June 2, while conducting a search on Crown land just south of Drayton Valley, Alta., officers located a variety of stolen items valued at thousands of dollars, including a jet boat, vehicles and trailers.
As RCMP officers approached one holiday trailer, two men ran out and fled toward the river and jumped in.
One made it across but Laird was swept down the river. His body was found earlier this week.
Mounties later arrested Jesse Arthur Proulx, 20, of no fixed address, near Drayton Valley.
He appeared Wednesday in provincial court in Breton, Alta., on charges of possession of stolen property.
