To find out who stole Jarell's iPod, we did a series of tests on different samples of foods taken from the scene of the crime and tested it to see if it matched up with any of Jarell's co-worker's lunches. We tested each food for glucose, starch, protein, and lipid. Turns out Jose's food samples matched the ones take from dry & liquid part of Jarell's evidence.
