The Texarkana Moonlight Murders, also known as the "Phantom Killer" case, is one of the most notorious unsolved murder cases in American history. The murders took place in 1946 in the border town of Texarkana, which straddles the state lines of Texas and Arkansas. Over the course of three months, a serial killer attacked eight people - five of whom were killed - under the cover of darkness, earning him his nickname. Despite an intense manhunt involving multiple law enforcement agencies and a number of suspects over the years, the identity of the killer has never been definitively determined or has it? The case has since become a popular subject for true crime enthusiasts and inspired numerous books, movies and TV shows.
