The FBI Agent Who Loved the Mafia More Than the Law And Got Away With It HT
October 1st, 2008, a Manhattan courtroom. Charges dropped, four counts of murder, gone. A 30-year FBI veteran walked out of that building, a free man, and 6 months later, he published a book about what a great agent he was. His name was R. Lindley Devcio, and the man he’d been protecting for two decades was one of the most prolific killers in Columbbo family history.
This is the story Hollywood hasn’t made yet because the truth is too uncomfortable. Not for the mob, for the FBI, the setup. What this story is really about. Let’s be clear about what this story is and what it isn’t. This isn’t a story about a corrupt cop taking envelopes of cash in a diner parking lot.
It isn’t about a beat cop looking the other way while a bookie runs numbers on his corner. Those stories are simple. Money changes hands. Loyalty gets purchased. The math is easy. But this is something more dangerous than that. Upper Lindley Devio was a supervisory special agent with the Federal Bureau of Investigation.
He ran the organized crime unit out of the FBI’s New York field office. He was by institutional measure one of the most effective mob hunters the bureau had ever produced. He built cases. He got convictions. He understood the Columbbo family from the inside out. The reason he understood it from the inside out is because for 20 years he was feeding information to a Columbbo family hitman named Gregory Scarpa Senior.
Not just receiving information, feeding it. Names, addresses, targets, the identities of witnesses, the locations of rivals. And while Debecio was feeding that information, Scarpa was using it to kill people. That’s not an allegation from a defense attorney looking for leverage. That’s what the evidence showed when investigators finally started pulling the thread.
The question was never really whether it happened. The question was whether anyone would ever be held accountable. The answer, it turns out, was no. Here’s what makes this story important. It isn’t just about one corrupt agent and one murderous informant. It’s about what happens when an institution decides that winning matters more than how you win.
when the FBI wanted the Colombo family dismantled so badly that they handed one of the family’s most dangerous killers a license to operate and called it intelligence work. Who was Gregory Scarpa Senior? Before you understand Dio, you need to understand Gregory Scarpa Senior, the Grim Reaper.
That was his nickname inside the Columbbo family and inside FBI files. Not a nickname given ironically, not street theater. A description. Gregory Scarpa Senior was born in 1928 in Brooklyn. By his 20s, he was running with the ProAache family, which would later become the Columbbo family. By his 30s, he was a soldier. By his 40s, he was one of the most feared enforcers in New York organized crime.
Scarpa wasn’t the kind of mobster who delegated violence. He participated in it personally, directly, repeatedly. Lone sharking, bookmaking, hijacking, murder. The FBI’s own files would eventually attribute over 50 murders to Scarpa across his career. 50. And for most of that career, he was simultaneously on the FBI’s payroll as a confidential informant.
You have to sit with that number. 50 murders while working with the federal government. Scarpo was first recruited as an FBI informant in 1961 under deeply questionable circumstances involving a mission to Mississippi during the civil rights movement. The FBI sent Scarpa to recover a confession about the murder of civil rights workers.
The methods Scarpa used were violent and extrajudicial, but he got results. And from that moment forward, the FBI understood something about Gregory Scarpa Senior. He was useful and useful people get protected. By the time R Lindley Devio inherited Scarpa as an informant in the 1980s, the relationship was already institutionally embedded.
It wasn’t Dcio who created this arrangement. He walked into something that had been running for two decades. But what Dvkio did with it and what he allegedly allowed to happen went far beyond any defensible interpretation of informant management. Scarpa was an earner. He generated money for the Columbbo family and information for the FBI.
Two income streams, two sets of bosses, total loyalty to neither. That’s the informant game at its most cynical. But Scarpa was also a psychopath in the operational sense. He didn’t use violence as a last resort. He used it as a preference. And somewhere along the way, Devkio stopped managing that violence and started enabling it. The informant relationship, how it started.
The FBC’s confidential informant program exists for a specific purpose. You cultivate a source inside a criminal organization. They give you intelligence. You build cases. You protect the source just enough to keep them operational. You never let the source use the relationship as cover to commit crimes. That’s the rule.
That’s the boundary. And in the relationship between Dvcio and Scarpa, that boundary dissolved so completely that investigators who later reviewed the case files couldn’t determine where the agent ended and the asset began. Dcio took over as Scarpa’s primary handler around 1980. Their relationship developed over the next decade into something the FBI’s own internal affairs unit would later describe as an unprecedented breach of protocol.
Dvecio called Scarpa my girlfriend in conversation with colleagues. He met with him privately in outside official channels without required documentation. He accepted gifts. He socialized with a man he was supposed to be running as a controlled asset. Here’s the thing you need to understand about long-term informant relationships.
They have gravity. The longer you run an asset, the more dependent on them you become. The more they know about your methods, your sources, your vulnerabilities, and the more indispensable they feel to the cases you’re building, the more you rationalize protecting them from consequences they have earned. Dio had built significant parts of his career on intelligence from Scarpa.
Scarpa knew that, and Scarpa, who had been playing institutional systems since 1961, knew exactly how to leverage it. By the late 1980s, according to testimony gathered years later, the relationship had flipped. Devio wasn’t running Scarpa. Scarpa was running Devecio, feeding him just enough actionable intelligence to justify the arrangement while extracting information that he used to protect himself and eliminate his enemies.
That dynamic had been brewing for years, but it didn’t fully detonate until 1991 when the Columbbo family went to war with itself. The Columbbo War, where it all collapsed. 1991 to 1993. The third Columbbo War. This wasn’t a war between families. It was internal. A faction loyal to imprisoned boss Carmine Persico on one side.
A faction backing acting boss Vicor Raina on the other. Two sides of the same family trying to kill each other in the streets of Brooklyn while the FBI watched. Except the FBI wasn’t just watching. The Columbbo War produced 12 murders and at least three dozen shootings over 2 years. It was the most sustained internal mob conflict New York had seen since the Banana War in the 1960s.
And Gregory Scarpa Senior was one of its most prolific killers, operating on the Persico side with what survivors would later describe as impossible intelligence. Scarpa knew where his targets were. He knew their routines. He knew which safe houses were actually safe and which ones weren’t. He showed up in the right place at the right time with a consistency that his rivals couldn’t explain.

Men who thought they were hidden got found. Men who thought they were protected got shot. According to testimony gathered by federal investigators and later presented during the 2006 indictment proceedings, the source of that intelligence was Lynn Devekio. The specific allegations are documented and specific. Devkio allegedly told Scarpa the home address of a rival faction member named Nicholas Granio.
Granio was killed on January 7th, 1992. Shot in his car in Benenhurst. Devio allegedly revealed the location of a witness who was cooperating with law enforcement. He allegedly passed information that directly preceded murders. Four murders in total were cited in the eventual indictment. four people who were alive and then were dead and whose deaths prosecutors connected to information that could only have come from inside the FBI.
Think about what that means structurally. The FBI had an active organized crime investigation running throughout the Columbbo War. Agents were surveilling, wiretapping, building cases in real time. And simultaneously, according to prosecutors, a supervisory agent inside that same investigation was feeding the intelligence to one of the war’s primary killers, the left hand building cases, the right hand supplying ammunition.
By the time the war ended in 1993, Scarpa was dying of AIDS contracted through a tainted blood transfusion. He pleaded guilty to three murders and racketeering in 1993 and died in federal custody in 1994. He took most of what he knew about the arrangement with Dcio to his grave, but not quite all of it. The investigation and the charges.
The investigation into Devcio started inside the FBI before it went anywhere else, which tells you something important about how uncomfortable this case made the institution. As early as 1992, while the Columbbo War was still producing bodies, agents inside the New York field office were raising concerns about Devio’s relationship with Scarpa.
They were logging irregularities, unofficial meetings, missing documentation. The pattern of Scarpa knowing things he shouldn’t have known. An internal affairs investigation was opened. It ran for years. And here’s what happened. Dio was cleared. 1996 internal affairs found insufficient evidence.
He retired from the FBLY with full benefits in 1997. Commended for his service. That should have been the end of it. For 9 years, it was. Then prosecutors in Brooklyn, specifically the Office of the Eastern District of New York, started pulling the threat again. A woman named Angela Clemente, a forensic investigator working independently with attorney Flora Edwards, had spent years reconstructing the evidentiary record.
They found witnesses the FBI hadn’t found or hadn’t wanted to find. They found documentation that reframed what the Internal Affairs investigation had reviewed. In March 2006, R. Lley Devio was indicted on four counts of secondderee murder. The charges alleged he had provided material assistance to Gregory Scarpa Senior in the killing of four people between 1984 and 1992. Devkio was 65 years old.
He pleaded not guilty. His attorneys argued the case was built on unreliable witnesses with their own legal vulnerabilities. The primary witness for the prosecution was a woman named Linda Shiro, who had been Scarpa’s long-term companion and who claimed to have been present for numerous conversations between Scarpa and Devcio in which specific intelligence was exchanged.
The prosecution’s case rested significantly on Skyro’s testimony, and that was the problem. Nawi got away with it. In November 2008, the charges were dropped. Not because Devkio was proven innocent, because the case fell apart before it ever got to a verdict. Here’s what happened. The prosecution’s entire case rested on one witness, Linda Shiro, Scarpa’s longtime companion, a woman who had lived inside that world for decades, who claimed she had been present in the room when Dcio and Scarpa exchanged that information, who said she had heard the
conversations with her own ears. names passed, addresses given, targets identified. She was the thread that held everything together. And the defense cut that thread. Defense attorneys went back through Shyro’s testimony in prior proceedings and found what they needed. Inconsistencies, contradictions, statements she had made in earlier cases that didn’t match what she was now telling prosecutors.
Not minor discrepancies, material ones, the kind that a skilled defense attorney can use to destroy a witness in front of a jury before she finishes her second sentence. The Brooklyn DA’s office made a calculation. Shirou could not survive cross-examination. And if Skiro collapsed on the stand, the jury would walk in under an hour.
So prosecutors dropped the charges before it came to that. They called it the right decision given the evidentiary circumstances. Maybe it was, but the result was the same either way. Devkio walked out of a Brooklyn courtroom a free man for the second time in his life. The first time was 1996 when the FBI cleared him internally.

This time it was a state court, different building, same outcome. 6 months later he published a memoir. He called it, “We’re going to win this thing.” That was the line he claimed to have told his colleagues the day he was indicted. The book was exactly what you’d expect, a dedicated agent, a witch hunt, a prosecution built on lies and motivated by politics.
A career of genuine service reduced to a footnote by people with agendas. He did interviews. He sat on panels. He was invited to speak. The rehabilitation was public, deliberate, and thorough. And the four people connected to the murder charges were still dead. That last part is the part nobody in the institutional conversation wanted to sit with.
Because here’s the problem. The FBI never solved and never fully confronted. Dio’s organized crime convictions were real. The cases he built over 30 years put actual criminals in federal prison. Dismantling his legacy meant examining every case he touched. It meant asking how much of that prosecutorial record was built on intelligence from a man who was murdering people while providing it.
It meant potentially reopening convictions, revisiting evidence, confronting a version of events where the FBI’s war on the Columbbo family and the Columbbo family’s internal war were being run partly by the same source. Nobody wanted that audit. The institution that trained Debecio, promoted him, cleared him, and pensioned him out, had too much invested in the version of the story where he was simply a great agent.
So that became the official version, and everyone moved on. What this story actually means, what this story [music] actually means, here’s what the story of Lindvekio and Gregory Scarpa actually reveals. It reveals the oldest problem in law enforcement intelligence work. The informant becomes the mission. The source becomes the objective.
And somewhere in that inversion, the people the institution is supposed to protect become acceptable collateral. The FBI needed Scarpa because Scarpa produced results. He named names. He described operations. He helped the bureau build cases against men who genuinely needed to be prosecuted. That part was real.
And that’s what made the arrangement so difficult to dismantle once it started producing the wrong outcomes because the [music] right outcomes and the wrong outcomes were coming from the same source. Think about the people who died during the Columbbo War while this arrangement was allegedly operating. They weren’t saints.
Several of them were themselves active participants in mob violence. But some of them were witnesses. Some of them were people who had decided to cooperate with law enforcement. And if the allegations are accurate, they were identified to their killer by a federal agent whose job was to protect them. That’s not a technicality.
That’s a betrayal of the most fundamental obligation law enforcement carries. The deeper pattern here connects to every informant scandal in organized crime history. The Whitey Bulier case in Boston, where FBI agents John Connelly and John Morris protected Bulier for decades while he murdered people and ran the Winter Hill gang with virtual impunity.
the same dynamic, the same inversion. The asset becomes untouchable. The handler becomes complicit and the institution looks away until it can’t anymore. And then it looks away some more. These aren’t aberrations. They’re the logical endpoint of a system that measures success by convictions and treats informants as instruments rather than human beings with their own interests and their own violence.
When you give a killer like Gregory Scarpa Senior, a relationship with the federal government and no meaningful oversight of how he uses it, you already know how the story ends. You just don’t want to write it down. The victims in this story don’t have famous graves. They don’t have movies made about them.
Nicholas Grantio isn’t a character anyone plays in a Hollywood production. He’s a name in an indictment that was eventually dismissed. He’s a case file in a Brooklyn DA’s office. He’s a cautionary footnote. But here’s what his death and the deaths connected to this case actually tell you. The mafia’s violence is visible.
It’s documented, prosecuted, dramatized, turned into entertainment. The institutional violence, the violence that happens because someone inside the system decided a useful informant was worth more than the people he was killing. that violence gets buried in internal affairs reports and prosecutorial decisions and [music] witnesses whose credibility gets destroyed before they can testify.
Dvkio died in 2023. He was 82 years old. He was never convicted of anything. His FBI pension was never touched. His career was officially unblenmished. Gregory Scarpa Senior is attributed with over 50 murders across a career that the federal government was informed about adjacent to and according to prosecutors actively facilitating for at least part of its duration.
Scarpa died in federal custody in 1994. He was 65. The people they killed together, if the allegations are true, got nothing. No justice, no acknowledgement, no accounting. That’s the real story behind the FBI’s war on the Columbbo family. Not the convictions, not the dismantling of the Borgata, the cost, the thing nobody totals up when they’re celebrating how many [music] wise guys went to prison.
The question of who else went in the ground while the bureau was counting its wins. Linda Veio loved the mafia more than the law. And the institution he worked for loved its conviction rate more than the truth. And everyone got away with it. That’s not a mob story. That’s an American story.
