Mei Leung, a 9-year-old Asian girl, was murdered on April 10, 1984, in the Tenderloin district of San Francisco. Her body was found in the basement of her apartment building at 765 O'Farrell Street. At the time she went missing she had been with her 8-year-old brother; he wandered away briefly after she went to search for a lost dollar bill and returned to find her dead.

For decades the case remained unsolved. In 2009 DNA from the crime scene was reported to match Richard Ramirez, the Night Stalker, and authorities said a second, unidentified attacker may have been present. Ramirez was already incarcerated on death row for other murders when the DNA link was made.

Did anyone in the Tenderloin at that time remember Mei or see anything that could still help explain who else was involved?
