As noram said, Barney has been in prison for the past twenty years for murdering someone. But he's the older brother of zwis and the two brothers are working on their relationship -- he was kind of a shit in his younger years. But he has four kids: nadalee, aswis, and a son that's coming in game. He's best friends with scoln and he has two kids coming into the game -- so she'll have plenty of family.
But as of tonight, Barney will be president of the Grim Aces. He's still working on figuring out how things work these days, life didn't change that much in prison. He loves his family, and hopefully she came to visit him on family day! And it bothers him that he missed so much, but what he did (he killed a rapist in front of an off duty cop) was worth it in his eyes and he'd do it again in a heartbeat
