He worked as a detective in the southern US before the outbreak, and some of the men he put behind bars had connections, so they sent out hit-men to take him out. On the night that they came for him he had stayed late working on a new case. They found his wife and little girl, home alone, after waiting hours for him to come home they ended up killing them both. He came home later that night too find both his wife and little girl were killed execution style in the bedroom. After a few months of drowning himself in grief he got a tip from a "friend" that one or more of the hit-men came from Chernarus and was likely back there. He was on his way there when the outbreak hit, and was on a plane that went down right outside of the border in Takistan. His goals, well main goal is to find the men and kill them or make them pay (he doesn't know if they are still alive) and survive. His name is Blain Fairchild. But not know anyone or if even that person could be one of the people that killed his wife and child he decided to go with the alias Carl Etheridge. He still has a one track mind when it comes to his family's killers, but I think he would and maybe evolve as he was forced to work with others. With him having been in the Police force and specially as a detective he can take care of himself which is why he has survived as long, and made his way here. He would be very wary around others preferably watching and observing others before talking to them, wanting to make sure of their motives before he gave them anything they could use against him. He would want to find out as much as he could about any and everyone he could, he made sure to keep a small notepad with him with various scribbles about things and people he met.
