At that #6 bunker down at the south part of the beach, there is a man name Jose Garcia that is trapped behind a fence. There were 2 Thugs there and 3 walkers, also a truck that looked in working condition, but I couldn't get into it. There's a big pile of luggage next to the truck too. So I'm looking around and I don't see any way to help Jose get out or for me to get in. Does anyone know how to do this mission?
