A crooked Sweetwater police officer-turned-serial killer from the height of Miami's "cocaine cowboys" era now has a date with death.

The Miami Herald reports Florida Gov. Rick Scott on Tuesday signed the death warrant for Vietnam vet and admitted neo-Nazi Manuel "Manny" Pardo, Jr.

The former cop admitted to killing nine drug dealers and witnesses during a four-month span in 1986, saying they were "scum of the earth."

Though initially arrested in May 1986 for the slayings of 40-year-old Ramon Alvero and his girlfriend 37-year-old Daisy Ricard, a police search of Pardo's Hialeah apartment revealed a calendar where he dated his killings and other evidence implicating him and a fellow officer in seven other Miami-area homicides earlier that year.

After a heavily-watched 1988 trial, a 12-member jury sentenced Pardo to death by electric chair. He asked for execution in his final address, claiming "I'm a soldier," and "I'm begging you to allow me to have a glorious end."

Pardo is scheduled to be put to death by lethal injection December 11 at 6 p.m. at the Florida State Prison near Raiford.
