For nearly three decades, a series of brutal sexual assaults and one murder haunted Montgomery County and the Washington DC metropolitan area. The perpetrator, known to law enforcement and the public as the “Potomac River Rapist,” was active from 1991 to 1998, leaving a trail of fear and unsolved cases. The mystery was finally brought to an end in 2019, thanks to advances in DNA technology and a collaborative cold case investigation, leading to the arrest of Giles Daniel Warrick. Warrick later died while awaiting trial.
