A Temple woman was killed Sunday night in a collision between a pickup truck and a tractor-trailer on State Highway 36, authorities said. Dena Self Montgomery, 59, was killed when her 2007 Dodge Ram pickup collided with a 2009 Peterbilt tractor-trailer driving by a Houston man, Texas Department of Public Safety Sgt. Bryan Washko said. The accident occurred at about 9:10 p.m. on Highway 36, just south of Burgandy Lane. Washko said Montgomery was traveling south on the highway when her truck crossed into the northbound land and collided with the tractor-trailer. Montgomery was pronounced dead at the scene by Bell County Justice of the Peace Cliff Coleman.
