The mysterious Moonlight Murders rocked the sleepy southern town of Texarkana in 1946. The killer, described by witnesses as wearing a white mask or sack with holes cut for eyes, was dubbed the Phantom Killer or Phantom Slayer.

The first attack took place on February 22, 1946, on a secluded road outside of town. The Phantom approached Jimmy Hollis and Mary Jeanne Larrey, a young couple parked in their car. He blinded them with his flashlight upon approach, then held them at gunpoint and ordered them out of the vehicle. The Phantom then told Jimmy Hollis to remove his pants and proceeded to beat him severely, fracturing his skull. The Phantom told Mary Jeanne Larrey to run. When she scrambled toward a ditch, he told her to change course and run toward the road. He then chased her down and sexually assaulted her before letting her run away again. In spite of the savagery of their attacks, both Hollis and Larrey survived. Others were not so lucky.

In March, Richard Griffin and Polly Ann Moore were found dead in their parked car at the end of a secluded road. A few weeks later they were joined by another young boy and girl, Paul Martin and Betty Jo Booker. Booker was the Phantom’s youngest victim, at only 15 years old. ~

In the first week of May, the Phantom Killer attacked what are his last official victims, a husband and wife, in their farmhouse northeast of town. Virgil Starks was killed by two shots to the back of the head, but his wife Katie survived, in spite of being shot twice in the face and having to run down the street to a neighbor’s house to get help.

Many people believe that local man named Youell Swinney—arrested in 1947 for auto theft—was the Phantom. His wife confessed to as much at the time, but by law she could not testify against her husband. She later repudiated her confession. Swinney remained in prison as a habitual offender until 1973, and died in 1994, without ever implicating himself in the murders. A 1948 cold case involving the disappearance of 21-year-old Virginia Carpenter from Texarkana is thought by some to have been the work of the Phantom Killer, though Swinney was already in prison by that time. And in 1999 and 2000 an anonymous woman contacted surviving family members of the Phantom’s victims to apologize for “what her father had done.” But Youell Swinney never had a daughter.

Regardless of the killer’s true identity, the town he traumatized has never been the same since the spring of 1946. Yet while other towns may have tried to forget such a gruesome legacy, Texarkana embraced it. When The Town That Dreaded Sundown was filmed there in 1976, locals were cast as extras. Every year around Halloween, the movie is screened at Spring Lake Park, near where one of the murders took place.

The Texarkana murders remain unsolved to this day.
