Bridgeport Police Chief Randy Singleton said the man killed in an explosion this morning at Bridgeport Tank Trucks was Jose Jesus Landeros, 50, of Chico. Landeros was using a welding torch on a trailer at Bridgeport Tank Trucks in Bridgeport when the explosion happened just before 8. Singleton said Landeros was working just outside the shop at the business when the explosion occurred. Singleton said it is very early in the investigation, but it appears that residual fumes in the tank ignited during the welding causing the explosion which knocked the victim back several feet. The blast caused damage to two other nearby vehicles, but no other employees were injured, and it appeared the shop did not sustain damage. The debris field stretched for a 100 foot by 100 foot area, Singleton said. In addition to Bridgeport police, the Bridgeport Fire Department, Wise County EMS and Wise County Fire Marshal Chuck Beard responded to the scene.
