Leroy Walker

 is a slaver from Paradise Falls, hunting runaway slaves near the Lincoln Memorial. He can generally be found in the Operations Office on the ground floor; go left while facing the steps into the Memorial itself. Do not go up the stairs, or everyone in the area will immediately become hostile.

Leroy plays a substantial role in Head of State: he and his team of slavers have already cleared the area of Super mutants, something Hannibal Hamlin requests of you. However, the slavers have laid claim to the Memorial and show no signs of leaving.

Leroy offers the player the opportunity to locate various items related to Abraham Lincoln; his intent is to destroy them in order to rob any escaped slaves of a figure and thus break their spirits. He asks the player to go to a "nearby ruin" which turns out to be the Museum of American History, and will pay caps for any item returned to him.

If notified of the slaver threat, Hannibal will ask the player to deal with them however he sees fit.

Alternately, the player can simply open fire on Leroy; his death brings no Karma penalty, but it will immediately set every slaver outside as hostile.

Leroy carries Metal Armor, which can be rather useful though it carries a -1 penalty to Agility.
