The San Francisco Police Department is reopening a 25-year-old homicide that may be linked to convicted killer Richard Ramirez, known during his 1984-85 spree as the Night Stalker.

Police said that detectives recently obtained a warrant to test Ramirez’s DNA based on new leads in the 1984 death of nine-year-old Mei Leung, who was sexually assaulted and killed in the basement of her home in the city’s Tenderloin district.

David Shinn, deputy director of the Bureau of Investigation, explained, “There are no charges at this time.” To get the DNA sample, inspectors went to San Quentin Prison, where Ramirez is awaiting execution.

Ramirez, who professed to being a “Satanist,” was convicted in 1985 of 13 murders–11 in Southern California and two others in the San Francisco area–along with five attempted murders, 11 sexual assaults’ and 14 burglaries. He was dubbed the “Night Stalker” for his preference of breaking into houses in the wee hours of the morning.
