IMHO...syringe in bottle of Gatorade posssibly still unrelated. Looks like a pre-purchased job like...
...that someone injected before/after going to the gym and tossed.
Interesting to note that it appears they checked for lidocaine and pesticide.
Ask yourself if you think Casey would place the cap back over the needle and put the syringe back in the packaging...
Gatorade botte...anabolic steroid...
Bond - thank goodness. I've wondered where you were.
