Baton Rouge, Louisiana, is once again gripped by terror as details emerge of a serial killer who preyed on women for years, his grotesque crimes hidden beneath a bland facade of science fiction fandom and quiet suburban life. Shawn Vincent Gillis, a man described by neighbors as a mild-mannered geek, has been unmasked as one of the most sadistic predators in the city’s dark history, confessing to the mutilation and murder of at least eight women. The city, already scarred by an epidemic of serial killers, now faces the horrifying reality that a killer walked among them for nearly a decade, hunting vulnerable women and leaving behind a trail of dismembered bodies.
The nightmare began in the 1990s, but it was not until the early 2000s that Baton Rouge realized it was in the grip of something far worse than a single madman. Police had already arrested Derrick Todd Lee, a convicted voyeur linked by DNA to the rapes and murders of at least seven women. Lee’s capture brought a temporary sigh of relief, but detectives soon discovered that another killer was still at large.
“We realized that there were murders that were being committed or had been committed that probably were not the result of Derrick Todd Lee,” one investigator recalled. The fear returned, deeper and more pervasive than before.
The new killer’s calling cards were brutal and unmistakable. Victims were found 𝓷𝓾𝓭𝓮, strangled with nylon zip ties, and often mutilated. The first to be discovered in this new wave was Katherine Hall, found at the end of a dark rural road, her body hacked and sliced to the bone.
“Her legs were really sliced up, man,” a detective said. Chillingly, her body was posed beneath a dead end sign, a twisted parody that investigators saw as the killer’s sick humor. Further examination revealed that the killer had 𝒔𝒆𝒙 with his victims after death, a detail that made prosecutors tremble.
“You’re talking about someone that’s sexually deviant,” said Prem Burns, the district attorney.
The murders escalated in savagery. Johnny Mae Williams was found face down in the woods, decomposing, her hands cut off. A little boy who discovered her was dismissed by his father, who thought it was a joke.
The father returned to find a human being, strangled and posed for maximum shock. The killer had even painted the victim’s nails black after death. “He was getting more bold and brazen since he had gotten away with it this long,” a detective noted.
But the boldness would yield a clue: a human hair found on the bones of her severed arms, identified as a body hair from a Caucasian male.
Several months later, the butcher struck again. Donna Johnston was found near a bridge, her body mutilated beyond recognition. The killer had cut off a butterfly tattoo from her leg and amputated her left arm below the elbow.
“She fought with him, and we know she fought because his DNA was under the fingernails of her right hand,” an investigator said. The city of Baton Rouge was under siege. Every nightly newscast reported the discovery of yet another woman stabbed, strangled, raped, and murdered.
“It has happened again,” news anchors intoned, as panic spread through the female population.
Police were stumped. Despite a load of DNA evidence, no matches were found in any database. Then, a tire track pressed into the mud near Donna Johnston’s body provided a break.
The track was a rare Goodyear tire, and only a couple hundred sets had been sold in the Baton Rouge area. Major Brian White dispatched a task force to visit every purchaser. “We asked them if they would voluntarily submit to an oral DNA swab,” White said.
“Most people said, ‘Sure, I’ve never killed anyone.’” But one man named Shawn Vincent Gillis stood out. Gillis was unemployed, lived with his mother, and was a huge Star Trek fan.
“He had on a USS Enterprise belt buckle,” a detective recalled.
When detectives questioned Gillis, his answers were suspicious. He admitted knowing one victim, Johnny Mae Williams, and offered bizarre explanations for his tire tracks near the crime scene. “I had some beer and needed to go to the bathroom real bad,” Gillis claimed.
He also explained away blood in his car by saying his wife had her period and “the blood just started flying everywhere.” Detectives were incredulous. “I’ve never heard such a crazy story,” one said.
Despite the outrageous statements, cops had to let Gillis go until DNA results came back. They secretly tailed him, afraid he might run or 𝓀𝒾𝓁𝓁 again.
The wait was agonizing. “It’s like being an expectant father, pacing in the waiting room,” White said. Then the phone rang.
“It’s him,” the crime lab said. A SWAT team raided Gillis’s home, finding him in bed with his girlfriend, Terry LeMoyne. Terry later recalled, “I yelled, ‘What’s going on?’
and Shawn just shrugged and said, ‘Sorry, honey bunny.’” When police told her she was living with a serial killer, she laughed, thinking they had the wrong house. But Gillis confessed, first to three murders, then to five more, listing names that had stumped detectives for years.
Gillis’s confessions were chillingly matter-of-fact. He described hunting women, using zip ties to strangle them, and then performing unspeakable acts with their bodies. He decapitated one victim on his kitchen floor, took a shower with another corpse, and cut off souvenirs.
“He considered them worthless,” a profiler said. His computer contained photos of victims staged in the trunk of his car, even capturing his license plate. But a legal problem emerged: Gillis had asked for a lawyer during interrogation, so his videotaped confessions were inadmissible.
Prosecutors feared the killer might go free.
A breakthrough came when a friend of victim Donna Johnston, Tammy Perpara, corresponded with Gillis in jail. Gillis wrote back, confessing in vivid detail. “Your friend died quickly,” he wrote.
“Her last words were, ‘I can’t breathe.’” The letter was a bombshell, providing the first-degree murder evidence needed. At trial, prosecutor Burns made the jury watch the clock for 90 seconds, the exact time Gillis said it took for Donna to die.
Gillis was convicted and sentenced to three life terms. But the horror of his actions remains, a stain on Baton Rouge, a city that now knows the true face of evil was hiding in plain sight.
