The gunman, Chad Hickman, was found dead in a wooded area near Whitlock Lake in Caldwell Township, the authorities said. A motive for the shootings was not immediately known.

His disclosure in an interview revived a key question about sobriety: whether someone who once drank dangerously can ever drink moderately.

About 20,000 people were ordered to evacuate over the weekend from the Bald Range fire. Weather conditions were not expected to provide much relief on Monday.

The Bald Range fire has burned more than 25,000 acres in British Columbia. At one point, the fire spread more than 2,000 acres in about an hour, officials said.
