WHEN DNA EVIDENCE FROM A WASHINGTON, DC, AIRPORT BREAKS OPEN A COLD-CASE MURDER INVESTIGATION, AUTHORITIES ARE LED STRAIGHT TO A KILLER OVER TWO DECADES AFTER THE CRIME

Correspondent Stephanie Ramos Reports on an All-New '20/20,' Friday, Sept. 12, on ABC, Streaming the Next Day on Hulu

When a wife and mother in an affluent suburb of Washington, D.C., fails to show up for work, her boss and husband go to her home looking for her. However, upon arriving, they soon find a crime scene waiting for them. A 911 call prompts authorities to discover the body of Leslie Preer. While investigating the murder, authorities initially set their sights on Leslie's husband as a suspect, but when DNA under Leslie's fingernails points to an unknown male, the case goes cold - until nearly 25 years later, when DNA evidence is collected at a D.C.-area airport, leading authorities straight to a killer. Correspondent Stephanie Ramos reports in an all-new "20/20," FRIDAY, SEPT. 12 (9:01-11:00 p.m. EDT) on ABC and streaming the next day on Hulu.
