LOUISVILLE (WAVE/CNN) - Investigators in Los Angeles say the man above is a possible serial killer.

Samuel Little, 72, is charged with murdering three women in California back in the 1980s.

Authorities say DNA evidence recently linked Little to the cases that had gone cold.

The homeless man was arrested at a shelter in Kentucky after authorities discovered his disability check was being delivered there.

Little is now jailed in California without bail.
