Botetourt Co., VA - One man is dead, and I-81 was closed for much of the day as crews worked to cleanup a chemical spill following a tractor trailer accident.

State Police say Wayne Kratzer, 51, of Pennsylvania, died in the wreck in, and authorities say he was trapped for more than three hours then died on the way to the hospital.

When rescue crews got on scene, they quickly realized they were dealing with a leak of Thioglycol, a chemical used in the textile industry but considered a poison.

Two barrels ruptured in the wreck, slowing down the rescue. It also forced residents within a half mile to evacuate their homes for about seven hours.
