Eloy Casados plays a character named Manolo Sanchez, which is the name of President Richard Nixon's valet.
Casados played the part of the real Manolo Sanchez in Ron Howard's Frost/Nixon (2008).
The Creeper's capture is based on the real life Night Stalker's capture in 1985. Both were identified by civilians on the street and chased down by an angry mob.
Manolo Sanchez aspires to be a police officer. The same actor playing Manolo (Eloy Casados) played a bit role as a police officer just eleven episodes earlier in the season.
