BUTTE CREEK CANYON — Valerie Cadwallader, ranting incoherently, was pointing a pellet gun rifle last spring when shot dead with a single round from a Butte County sheriff’s deputy’s assault rifle.

That’s according to Brian Marklund, the owner of the pellet gun and of the property where his friend Cadwallader, 48, was killed May 8 by deputy Tyler Dentinger.
