On January 15, 1947, Betty Bersinger pushed her three-year-old daughter in a stroller down a weedy stretch of South Norton Avenue in the Los Angeles neighborhood Leimert Park . What she saw that morning — a bright-white form lying in the tall grass — would become one of America’s most enduring murder mysteries. The body of 22-year-old Elizabeth Short, bisected at the waist and drained of blood, launched what became the LAPD’s most extensive investigation in its history. No one was ever charged.
