You are right, the SPD handling of evidence in this case was murky.

"an inventory was being conducted of Martin's person. I noticed the items collected for evidence were a bag of skittles, an Arizona ice tea can and head phones."

"The victim had $40.15 in US currancy, a bag of skittles candy, a red 7-11 red lighter in his pockets, headphones next to him, and a photo pin on his sweatshirt. After making inquires I was told that the Arizona lce Tea can was from inside the victim's Sweatshirt pocket and had come out while first aid was being given."
The 7-11 bag was found on the sidewalk close to Martin's body. It is marked #2. Why would Martin take the can out of the bag at the spot where he was shot? Was he carrying the empty bag just for the heck of it? If he had intended to jump Zimmerman at the 'T' wouldn't he have gotten rid of it before jumping him?
Humm ... maybe Martin should have used the bag to smother Zimmerman. Zimmerman said Martin covered his mouth and nose, yet he was able to scream "HELP" loudly and clearly, over and over again. How was that possible?
