An officer from the Los Angeles County Sheriff's Department guards an intersection outside the Twin Towers Correctional Facility in L.A. on Feb. 8, 2013.
A 72-year-old has pleaded not guilty to killing three women in the late 1980s in South Los Angeles, where prosecutors allege he strangled the victims during sexual attacks that left behind DNA.
Samuel Little came to court in a wheelchair to enter the plea Monday.
He was extradited to California from Louisville, Ky. following a September arrest on an unrelated narcotics warrant.
A longtime transient with a police record spanning two dozen states, Little is accused of killing 41-year-old Carol Alford, 35-year-old Audrey Nelson and 46-year-old Guadalupe Apadaca.
Investigators believe he killed the women while on parole for the assault and false imprisonment of two San Diego women.
Little moved to California after he was accused but not convicted of two murders and two attempted murders in Florida and Mississippi.
