It started with a stolen computer monitor. Honestly, if you told someone in 2012 that a petty theft charge would lead to a string of high-profile assassinations in a quiet Texas suburb, they’d have called you crazy. But the saga of Kaufman County Eric Williams is one of those real-life stories that feels like it was ripped straight from a dark noir novel, except the blood was real and the victims were public servants just doing their jobs.
Eric Williams wasn't some career criminal from the underworld. He was a lawyer. A former justice of the peace. A guy who sat in a position of trust. When that trust was shattered, he didn't just go away quietly. He nurtured a grudge so deep and so toxic that it ended in the deaths of District Attorney Mike McLelland, his wife Cynthia, and Assistant DA Mark Hasse.
How a Petty Theft Sparked a Killing Spree
To understand Kaufman County Eric Williams, you have to look at the 2012 theft trial. It sounds almost ridiculous when you say it out loud. Williams was caught on camera taking computer monitors from a county building. Because he was a public official, the prosecutors—Mark Hasse and Mike McLelland—didn't go easy on him. They couldn't.
They prosecuted him aggressively. He lost his job. He lost his law license. In his mind, he didn't see a man who had committed a crime and was facing the consequences. He saw two men who had systematically destroyed his life.

The bitterness didn't just sit there. It fermented.
Most people, when they lose everything, they either spiral or they try to rebuild. Williams chose a third option. He chose tactical, calculated warfare. He spent months planning. He bought old cars that couldn't be easily traced. He scouted the movements of his targets. He turned his storage unit into an armory.
The Day the Courthouse Changed Forever
January 31, 2013, was a cold morning in Kaufman. Mark Hasse was walking from his car to the courthouse, just a normal workday. Suddenly, a gunman approached and opened fire in broad daylight. Hasse died on the pavement.
The town was paralyzed. People thought it was the Aryan Brotherhood. There were rumors of Mexican cartels taking out prosecutors. Nobody was looking at the disgraced former JP with a penchant for electronics. That was the genius, and the horror, of the plan.
Security at the courthouse became a fortress. Mike McLelland, the DA, started carrying a gun everywhere. He talked to the press, defiant, calling the killers "scum." He didn't know the "scum" was someone he had sat across from in a courtroom, someone who was watching his every move.
The Easter Weekend Massacre
Two months later, over Easter weekend, the violence escalated to a level that felt domestic. This wasn't a public hit on a street corner anymore. This was an invasion.
Williams drove to the McLelland home in Forney. He wore a tactical vest. He carried an assault rifle. He didn't just kill Mike McLelland; he killed Cynthia McLelland too. It was brutal. It was personal. The sheer volume of shell casings left at the scene told a story of pure, unadulterated rage.
Kaufman County became the center of the national news cycle. Police officers slept on the floors of the courthouse. Judges were escorted by SWAT teams. The fear was palpable because, at that point, the police still didn't have their man.
The Digital Breadcrumbs and Kim Williams
How do you catch a guy who knows how the law works? You look at the people around him.
Investigators eventually circled back to Eric Williams. The breakthrough came from an anonymous tip—an email sent through a secure server that the sender thought was untraceable. But in the digital age, nothing is truly untraceable if the FBI is looking hard enough.
Then there was Kim Williams. Eric's wife.

She was his shadow. In a shocking twist, it turned out she wasn't just a bystander; she was the getaway driver. When she finally talked, the whole house of cards came down. She described the "death list." She described Eric's glee after the killings. It was chilling. She told investigators how they threw the weapons into Lake Tawakoni.
When divers pulled those guns from the murky water, the case against Kaufman County Eric Williams was effectively closed.
The Trial and the Death Penalty
The trial was moved to Rockwall County because, let's be honest, there was no way Eric Williams was getting a fair shake in Kaufman. Everyone there had lost a friend or a colleague.
The defense tried to paint a picture of a man who had suffered a brain injury, suggesting his impulse control was gone. It didn't fly. The jury saw the planning. They saw the storage unit filled with masks, guns, and a literal getaway car.
In 2014, Eric Williams was sentenced to death. He currently sits on death row in Texas. Kim Williams received 40 years for her role in the murders.
Why This Case Still Haunts Texas
This wasn't just about three murders. It was an attack on the very idea of the rule of law. When a prosecutor is killed for doing their job, it strikes at the heart of the justice system.
If people are too afraid to prosecute crimes because they might get shot in the parking lot, the system breaks. That's why the response from Texas law enforcement was so overwhelming. They had to prove that the state wouldn't be intimidated.
Lessons from the Kaufman County Tragedy
Looking back at the Kaufman County Eric Williams case, there are specific takeaways for legal professionals and law enforcement:
- Security for Public Officials: The case changed how DAs and judges think about their personal safety. Home security systems and personal protection are no longer seen as "extra"—they are requirements.
- The Danger of "Low-Level" Grievances: We often focus on high-stakes organized crime, but the most dangerous threat can sometimes be a disgruntled insider with nothing left to lose.
- Digital Forensic Importance: The email that Williams sent was his undoing. It proves that even those who think they are tech-savvy often leave a trail.
- The Role of Spousal Involvement: It’s a reminder that investigators must look at the domestic circle. Kim Williams’ cooperation was the final nail in the coffin.
The courthouse in Kaufman still stands, and the work continues, but the names of Mark Hasse, Mike McLelland, and Cynthia McLelland are etched into the memory of the town. They are a reminder of the cost of justice.
For those interested in the deeper legal mechanics, the trial transcripts and the subsequent appeals for Eric Williams provide a grim but fascinating look into the psychology of a man who believed he was above the law he once swore to uphold. The most actionable step for anyone in the legal field today is to take threat assessments seriously. If a defendant or a former colleague shows signs of obsessive fixation or extreme resentment, it shouldn't be dismissed as "just venting." In the case of Eric Williams, the venting was merely the prelude to an execution.
