The Otto Family is a family of survivalists living in southern California near the border with Mexico. The head of the family, Russell Otto, appeared in the Season 2b episode Wrath when Ofelia Salazar crossed into the U.S. The rest of the family is set to appear in Season 3.
Some time prior to the outbreak, the family banded together with other like minded individuals to set up a Survivalist Organization, with a view to surviving the fall of the democratic form of government. Their base of operations appears to be Broke Jaw Ranch.
