What about the drug dealer that was riding with GF?
One scenario I believe GF was either an undercover cop or a snitch, and events that happened the day GF was "murdered" were designed in order to catch a drug dealer.
Either that, or GF was involved in some kind of kid fucking/trafficking business.
Someone wanted him gone… copsexecuted him.
We all know he was in a porn video, so he was close to the weirdos for sure. His girlfriend had direct access to product, note the pin she wore specifically for the entire world to see.
