Leroy Walker

 is a slaver from Paradise Falls, the leader of a 6-man squad of Slavers who have occupied the Lincoln Memorial while hunting for the runaway slave group Temple of the Union. He can usually 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.

Head of State
Leroy plays a substantial role in the quest, 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. If notified of the slaver threat, Hannibal will ask the player to deal with them however they see fit.

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

Tip: If the player chooses to tell Leroy where the escaped slaves are, he, Silas and the other Slavers will start running to the Temple of the Union. Follow them, and when they are standing close enough to each other they can be easily killed with a Fat Man or any similar massively explosive weapon.

If the player sides with the slavers, and should Leroy survive the ensuing battle at the Temple of the Union, he can later be found at the food kiosk in Paradise Falls.

Unmarked quest: Lincoln's Profit Margins
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 figurehead 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.

Bugs

 * Leroy Walker may disappear from the memorial without a trace. There is no known reason for this.
 * Leroy Walker may appear past the steps in the memorial itself instead of in the maintenance room where Silas leads the player. This makes it difficult, if not impossible, to speak to Leroy, as the slavers on the steps to the memorial are hostile.

Appearances
 only appears in Fallout 3.
