Bo Crowder is the father of Boyd Crowder and the uncle of Johnny Crowder. He is a nasty old man, hardened by years of running Harlan County's meth operation and associating with drug cartels. He seems to have few genuine feelings for his son and is more interested in returning to power and wealth after being released from prison. His shady business dealings put him in close association with Arlo Givens and, by extension, U.S. Deputy Marshal Raylan Givens.
