Frederick Charles "Freddy" Krueger is a character created by Wes Craven and is the main villain and killer from the slasher film series A Nightmare on Elm Street. In 1968 he was burned to death by the citizens of Springwood. After his death he began killing the children of the city in their dreams.
Amanda Krueger was a nun working in a hospital, and was raped by over 100 psychopaths. She became pregnant with a son, who was named Freddy. Later in his life he became a murderer in Springwood notorious for killing children. The media labeled him the Springwood Slasher. He was apprehended, but later released because of a technicality. According to the original film, it was because someone didn't sign the search warrant in the appropriate place, but according to the first episode of Freddy's Nightmares, it was because he was not read his Miranda rights. The parents of the children tracked him down and found him in the boiler room where he took his victims. The parents poured gas into the room and set him on fire, which caused his melted-like facial features.
