i have an idea about the general story line of the game. i think that the 3 people you see in the trailer are all related. the older man being the farther. in the trailer he does say he moved to los santos with his kids and wanted 'to get out that line of work'. so mabye they are a crime/mob family that has moved to los santos. Also they look alike(facial features and hair lines) when they are breaking into the shop. Plus i think it fits into the rockstar description that says 'Grand Theft Auto V focuses on the pursuit of the almighty dollar' what do you guys think?
