A theory I've always held is that someone in Pacs camp told Orlandos group when Pac n Suge left Luxor, and that they were headed to 662.
Again, all these nikkas are LA gang bangers. They know each other, know of each other, knows someone that knows someone else, etcetera. Pac n Suge were out there with 20-30 people. If theres a price out on Pacs head, they probably paid someone in Pacs camp to page them when they were leaving the Luxor and headed to 662.
we all know, suge was notorious for abusing people in his own camp at times. it is likely that someone close to them would want revenge
