30 year old Shannon Sampson of Minden was on the job as a supervisor with GATX Rail Field when he fell into a rail car and later died from his injuries. According to Webster Parish's public information officer, Jenny Reynolds, Sampson fell after passing out due to a lack of oxygen.

As reported by the Shreveport Times on their website on March 12th:

Sampson was flown from the scene to a Shreveport hospital, where he later died. Bossier Parish Fire District No. 1 Assistant Chief Skip Pinkston told deputies the oxygen level in the rail car was 7.3 percent, 'which is about half of what we need to function,' Webster Parish Sheriff Gary Sexton said.
GATX Rail Field disassembles and refurbishes rail cars. According to another employee, workers often deal with rail cars that contain (or have held) hazardous materials. This incident is still under investigation to determine what caused Sampson's fall.
