It was a magical can ...
In the photo in post #55, it states that the can was found in Martin's waistband. Maybe he wanted to free up his hands because he wanted to smoke a joint???
It must have been since detectives said it was still cold.
How he could have tolerated a cold can of anything in his pants is a wonder.
And how it didn't end up in his underwear is a mystery.
Not to mention how it morphs back and forth from "ice tea" to "watermelon juice".
Oh well -- bag it and tag it.
