As OSHA determines the cause of the deadly explosion that killed five workers at Didion Milling Plant, CBS 58 is continuing to follow the journey of one man who survived the blast.

Collin VanderGailen, 23, wasn’t working his normal shift when he was thrown under a train car at the plant in May. He lost both of his legs in the blast which was tough news for a former high school basketball star.

On Thursday, VanderGailen started walking for the first time since the blast with the use of prosthetics. CBS 58's Whitney Martin has his story.
