13. The murder of Chandra Levy
Employed as an intern at the Federal Bureau of Prisons in Washington D.C., Chandra Levy vanished in May 2001. Her remains were discovered in Rock Creek Park a year later, leading to a controversial murder investigation. The glare of media attention fell on Gary Condit, a Democrat Congressman who had an affair with Levy, and the publicity destroyed his career. But Levy’s killer was later identified as a Salvadorian called Ingmar Guandique. He was finally convicted for Levy’s murder in 2010 and later sentenced to 60 years in prison.
12. El Segundo cop killings
On July 21, 1957, a drifter robbed four teenagers necking in a quiet lane in Hawthorne, east of El Segundo, California. He raped one of the girls and stole a car. Later that night, he killed two officers from El Segundo Police Department after they stopped him for running a red light. He evaded capture for 45 years. Then in 2003, national digitization of fingerprint records led police to Gerald Mason, a well-to-do retiree living in suburbia in South Carolina. He confessed to the crimes and died in prison in 2017.
