Not a good search party. Maybe no one even bothered to look, or try to track his activity pattern. Most professional kitchens receive or retrieve or inventory freezer items on the same days of the week, and at the same time of the workday. What? Nobody entered that walk in for almost five days running? I almost have to doubt this story.
Sounds like BS to me, -22C for 5 days he would of been frozen solid. I can buy 3 hours, not 103.
