Andy and Michael Dempsey are brothers. They admit to having a good, loving childhood. They murdered their parents and seemingly go on a killing/robbing spree. Michael is the older brother, Andy the younger. Andy seems to have a love for kidnapping beautiful women they come across to act as his playthings.
They go to a dinner, awaiting a man named Jamie who was supposed to get them out of the country before the police could find them. Here, they come across Marcus and his support team who are acting as a cell of the Shepherd Organization.
They are presumably dead.
