During October 2002, Washington DC and its environs were terrorized by a serial shooter who became known in the media as the Beltway Sniper. The killer appeared from nowhere, picking victims at random, gunning them down as they went about their daily business. At least 10 people would fall victim to the deadly sniper with many more injured.
But just three weeks into the killing spree the police got a break when they arrested former army sergeant John Allen Muhammad and his teenaged accomplice Lee Malvo. Muhammad would eventually be sentenced to death and executed by lethal injection. Malvo was given a life sentence.
