The Vancouver (Canada) Sun reports that a 14-year-old nephew of polygamist leader Winston Blackmore was killed in an accident at a lumber mill.

Blackmore, right, is the founder of a polygamist community in Bountiful, British Columbia, that is a spin off of Warren Jeff's Fundamentalist Church of Jesus Christ of Latter-day Saints (FLDS).

Mounties say Steven Clancy Blackmore was apparently trying to manipulate some heavy equipment at a lumber mill with a pole when the weight of the equipment "must have been too heavy and fell back on the victim. When found by his father, the pole was pinned across the victim's neck."

The mill is owned owned by Duane Palmer. Palmer is a bishop in Bountiful and superintendent of the government-funded Mormon Hills School.

The boy's father, Karl Blackmore, denied his son was employed at the site, saying his son had tagged along to the mill to unload some wood. Canadian authorities are investigating whether children are working at the mill.
