<p>DENVER — The estranged husband of a U.S. Forest Service worker accused of setting the worst wildfire in Colorado history told investigators he had never written a letter to his wife, undercutting her story that she had accidently kindled the blaze by burning the letter in a campfire ring. That information came to light Thursday during a pretrial hearing for Forest Service recreation technician Terry Barton, 38, an 18-year veteran of the agency. Barton pleaded innocent in federal court to four felony counts lodged against her by a grand jury on Wednesday.</p>
