Seymour Brotherton was a soldier who used to work with Thomas Stern.
Before September 2009Edit
Comments by Stern suggest that Brotherton was engaged in illegal doings even while a soldier. The two were on polite terms, but did not like each other.
After retiring, Brotherton smuggled narcotics into America from Ciudad Juarez, Mexico. He also occasionally smuggled illegal immigrants if they had enough money.
Stern, Hans Donitz, and Werner Donitz met him in a bar in Texas. Brotherton agreed to drive Hand and Werner to the old terrorist hideout so long as Stern joined them. Both sides fulfilled their half of the bargain. (Disruptive Selection)
