Ohh nooo! I once put a very nice, brand new, never worn summer weight shirt belonging to DH into the freezer in a bag damp from its first washing to be ironed later. Some time later he asked about the shirt and we did a search. Never did turn up. We also put anything potentially stinky such as bones, chicken skin, etc. in a bag in the freezer until trash day. The only thing we could figure out was one of us thought that shirt was trash.
Look one more time in your vehicle. Then ask family members, then search the house where you might put something, THEN search the whole house. I bet it turns up. Let us know.
