San Francisco police believe they have uncovered another killing by the "Night Stalker" serial killer who terrorized the Bay Area in the '80s. DNA evidence has linked Richard Ramirez to the 1984 murder of 9-year-old Mei Leung, who was sexually assaulted and killed in the basement of a hotel. The breakthrough was made by homicide detective Holly Pera, who was a rookie at the time of Leung's slaying and never lost interest in the case.
"I was a new police officer at the time. That's part of the reason that the case was relooked at," Pera told CNN. "It's the type of case as a new officer, a case involving a little girl, that you don't forget." The victim's family members have been contacted and are grateful to learn of the breakthrough, said a police official. Ramirez, who has been on death row since being convicted of 13 murders in 1988, is a suspect in several other unsolved killings.
