It was a hot May morning in 1976 when the quiet suburb of Elk Grove Village, Illinois, lost its innocence. People don't really use that phrase anymore—"losing innocence"—because it sounds like a cliché from a bad noir novel, but in this case, it fits. Mary Columbo and her 13-year-old son, Michael, were found slaughtered in their home. The father, Frank Columbo, was there too. It wasn't just a robbery gone wrong. It was a godawful mess of overkill that pointed toward something deeply personal and incredibly dark.
When the names Patricia Columbo and Frank DeLuca hit the headlines, the Chicago area buckled. This wasn't some random drifter. This was the daughter. This was her older, married lover.
Honestly, if you look at the crime scene photos—which I don't recommend unless you have a stomach of iron—you see a level of rage that's hard to process. Michael, a young teen, had been stabbed nearly 100 times. Why? That’s the question that kept investigators up at night. Was it just about a family feud, or was there something more parasitic happening between the 19-year-old Patty and the 38-year-old DeLuca?
The Twisted Dynamic of Patricia Columbo and Frank DeLuca
Patty Columbo wasn't your typical rebel. She was smart, attractive, and seemingly had everything. But then she met Frank DeLuca at the Walgreens where they both worked. He was a pharmacist. He was also nearly twenty years older than her, married with five kids, and, by most accounts, incredibly manipulative.
Their relationship was a powder keg.
Frank Columbo, the father, was a "tough guy" type who didn't take kindly to a middle-aged man preying on his daughter. There were confrontations. Heated ones. Threats were traded like baseball cards. This wasn't just a "forbidden love" story; it was a slow-motion train wreck fueled by DeLuca’s apparent obsession and Patty’s escalating resentment toward her parents' boundaries.
You’ve got to wonder what goes through a person's head when they decide that the only way to be "free" is to eliminate their entire bloodline. It wasn't just the parents. They killed the kid. They killed Michael. That’s the part that always stops people cold.
The Night of the Murders
May 4, 1976.

The plan was supposedly clinical, but the execution was chaotic. Reports from the trial and subsequent parole hearings paint a picture of a frenzied attack. The elder Frank was shot and beaten with a lamp. Mary was shot and stabbed. Michael was lured into the hallway and essentially butchered.
There’s this chilling detail that often gets overlooked: Patty allegedly checked her brother's pulse to make sure he was dead.
The motive? It’s often cited as "freedom" or an inheritance, but looking at the psychological profiles, it feels more like a shared psychosis between Patricia Columbo and Frank DeLuca. They fed off each other’s grievances. DeLuca reportedly told Patty that her father was planning to have him killed, which might have been the spark that turned a bad situation into a triple homicide.
The Trial That Shook the Midwest
The 1977 trial was a circus. You have to remember, this was before the 24-hour news cycle, but Chicago was obsessed. Patty was portrayed as a "femme fatale," a cold-blooded siren who led a family man astray. DeLuca was seen as the predator who corrupted a young girl.
The prosecution’s star witness was a man named Roman Sobczynski. He testified that Patty and Frank had tried to solicit him to commit the murders before they eventually decided to do it themselves. This blew the "heat of passion" defense out of the water. This was premeditated. It was calculated.
- The jury didn't buy the "manipulated girl" routine.
- They didn't buy DeLuca’s claims of innocence.
- Both were sentenced to 200 to 300 years in prison.
Even back then, those sentences were meant to ensure they’d never breathe free air again. Illinois law has changed since then, leading to a decades-long saga of parole hearings that keep ripping the scabs off the community’s collective memory.
Life Behind Bars and the Parole Battle
If you follow true crime, you know that the story doesn't end with the "Guilty" verdict. For over 45 years, Patty Columbo has been a model prisoner. She’s earned degrees. She’s worked with other inmates. She’s become a cause célèbre for some who believe she’s been rehabilitated.

But then you talk to the surviving relatives. Or the retired cops.
They remember the house on Lunt Avenue. They remember the sheer volume of blood. Every time Patty or Frank DeLuca comes up for parole, the opposition is fierce. The Illinois Prisoner Review Board has heard it all. They’ve heard the apologies. They’ve seen the "changed woman." And yet, they almost always vote "no."
Why? Because the crime was so heinous that "rehabilitation" feels like an insult to the victims. In 2023, Patty was again denied parole. The board pointed to the brutality of Michael’s death. You can’t just "good behavior" your way out of killing a 13-year-old with that much cruelty.
What Most People Get Wrong About the Case
A lot of folks think this was a Manson-style cult thing. It wasn't. It was much more mundane and, in some ways, more terrifying because of that. This was a suburban tragedy.
Some people also think Patty was the sole mastermind. While she certainly had the motive (in her mind), the physical evidence and the testimony suggest DeLuca was the heavy. He was the one who brought the "muscle" and the clinical detachment. They were a duo. One provided the target; the other provided the means.
There’s also a common misconception that they’ll eventually get out because of their age. Frank DeLuca is now an elderly man in his 80s, reportedly in failing health. Patty is in her late 60s. But in the eyes of the law in 1970s Illinois, 200 years meant 200 years. Unless the board has a massive change of heart, they are dying in the system.
The Psychological Shadow
What makes the story of Patricia Columbo and Frank DeLuca so enduring is the psychological "why."

Experts have debated for years whether Patty was a victim of "coercive control" before that was even a legal term. Was she groomed? Probably. Was she a willing participant? The evidence says yes. It’s that gray area that makes people uncomfortable. We want our villains to be pure evil and our victims to be pure good. This case doesn't give us that luxury. It gives us a messy, violent, and deeply disturbing look at what happens when obsession meets resentment.
The Columbo house was torn down years ago. A new one stands in its place. People walk their dogs past the spot where Michael Columbo used to play, likely having no idea that one of the most famous murders in Illinois history happened right under their feet.
Key Takeaways for True Crime Enthusiasts
If you’re researching this case or looking to understand the legal ramifications of old Illinois sentencing laws, keep these points in mind:
- The Sentencing Gap: Patty and Frank were sentenced under an old system that allowed for "indeterminant" sentences (like 200-600 years). This is why they still have parole hearings every few years, unlike modern "life without parole" sentences.
- The Impact of Victim Advocacy: This case was a landmark for how victim's families interact with the parole board. The Columbo relatives have been incredibly vocal, which heavily influences the board's decisions.
- The Co-conspirator Factor: Never underestimate how much the testimony of "friends" like Sobczynski matters. Without that testimony of prior solicitation, the defense might have successfully argued that it was a spontaneous domestic dispute.
If you want to dive deeper, look for the book The Girl Next Door (not the Jack Ketchum one, the one specifically about this case) or look up the old Chicago Tribune archives from 1976. The reporting at the time was raw and incredibly detailed.
The story of Patricia Columbo and Frank DeLuca isn't just a "spooky story." It’s a case study in how a family can be destroyed from the inside out. It serves as a grim reminder that the most dangerous people in your life aren't always strangers in the dark—sometimes, they're the people sitting at your dinner table or the person you're "in love" with.
Actionable Next Steps:
- Research the "Solicitation" angle: If you're a law student or interested in forensics, look at how the solicitation of Roman Sobczynski changed the prosecution's strategy.
- Visit the Illinois Prisoner Review Board website: You can actually see the public records and schedules for upcoming parole hearings if you want to see how the case is handled today.
- Read the original 1976 transcripts: Many are digitized in library databases and offer a much more nuanced look at the evidence than a 10-minute YouTube video ever could.
