Duncan Alexander Burrell Gordon went to work as usual on the night shift at Industrial Recycling and Recovery in Greer on May 4.
He left for lunch around 11 p.m., clocking out as he went and in when he came back. He was seen around 2 a.m. on top of a machine that can shred metal but is mostly used to shred plastics.
The day flipped to Wednesday. No one has seen the 20-year-old since.
