ANCHORAGE — The nail found in the truck tire of the man charged with killing two co-workers at a Kodiak Coast Guard facility likely was inserted mechanically, not picked up along a roadway, a tire expert said Monday.
The weathered nail, about 3.5 inches long and bent 7 degrees, was perpendicular to the tire tread, Gary Bolden testified. The head of the nail showed no abrasions that would have indicated it had been driven on asphalt or gravel, Bolden said.
“My conclusion was that it was inserted manually,” Bolden said.
