Red collar crime is white-collar crime that turns violent. The term describes fraudsters — embezzlers, inside traders, con artists, people running long financial schemes — who assault, threaten, or kill someone to keep the fraud from being discovered. Violence is not the original goal. It arrives late, as a reaction to the threat of exposure, and it is usually aimed at the specific person who got too close to the truth: an auditor, a spouse, a business partner, a witness.
Attorney and criminologist Frank Perri coined the term after more than two decades studying cases where fraud and violence overlapped. His research, published through the International Journal of Psychological Studies, defined red collar criminals as “a sub-group of white-collar offenders who are violent” whose motive is “to prevent the detection and or disclosure of their fraud schemes through violence.”1Canadian Center of Science and Education. Red Collar Crime The “red” is a reference to blood. Before Perri’s work, fraud investigators and compliance officers were generally trained to think of white-collar offenders as nonviolent by definition.
How It Differs From White-Collar and Blue-Collar Crime
White-collar crime is financially motivated and committed in a business or professional setting. The FBI describes it as “generally non-violent in nature,” covering public corruption, healthcare fraud, mortgage fraud, securities fraud, and money laundering.2Federal Bureau of Investigation. What is White-Collar Crime The category also includes embezzlement, insider trading, tax evasion, and intellectual property theft.3Legal Information Institute. White-Collar Crime The harm is to money, not bodies.
Blue-collar crime, in broad usage, covers street-level offenses like theft, assault, and drug crimes, where force is often the method of the crime itself.
Red collar crime sits between those categories. It begins as white-collar crime and stays that way, sometimes for years. Violence enters only when the offender believes discovery is imminent: an audit finds the discrepancy, a partner checks the books, a spouse notices the bank statements. The violence is instrumental. It exists to protect the fraud.
Why Some Fraudsters Escalate
Most embezzlers and con artists do not become violent. Perri’s work focused on what distinguishes the ones who do. He identified antisocial qualities visible before the violence occurred, and pointed to behavioral risk factors like narcissism and psychopathy to explain the escalation.1Canadian Center of Science and Education. Red Collar Crime
Narcissistic traits produce entitlement and an inability to accept blame. Exposure threatens not just liberty but the offender’s self-image as a successful professional, so the stakes feel existential. Psychopathic traits — thin empathy, shallow emotional response, comfort with manipulation — lower the internal barrier to using violence to solve a problem.
The combination is what makes these offenders hard to spot in advance. They often read as charming, competent, and confident. Colleagues and even close family may have no idea a scheme is running. The mask slips when detection becomes a real possibility.
Warning Signs That a Fraudster May Turn Violent
Because red collar violence is triggered by the threat of exposure, the warning signs tend to appear during audits, investigations, or direct confrontations. The Association of Certified Fraud Examiners has grouped the red flags into several categories.4Association of Certified Fraud Examiners. Knowing the Red Flags of Red-Collar Fraudsters Could Save Your Life
Physical signs are stress responses: clenched jaw or fists, pacing, violating personal space, destroying property, trembling, rapid breathing. In the context of a fraud inquiry, they signal that the person feels cornered.
Intimidating behavior is more deliberate. The person may become argumentative or uncooperative out of proportion to the situation, display sudden anger, challenge authority, or actively try to shut down an audit or investigation. People who have nothing to hide rarely fight an audit aggressively.
Verbal warnings are easy to dismiss. Lines like “what comes around goes around” or “I don’t get mad, I get even” get written off as jokes. Combined with other red flags, they reveal how the person thinks about conflict — as something that calls for retaliation.
Personality patterns fill out the picture: blaming others, entitlement, difficulty accepting criticism, and a habit of casting themselves as the victim. When someone who has been stealing for years believes they are the wronged party, cost-benefit thinking about consequences stops working.
Real Cases That Followed the Pattern
Documented cases show the same sequence: a long-running financial scheme, a moment when exposure becomes likely, and a violent response.
George Hansen and Mary Ann Clibbery
In the 2004 holiday season, 69-year-old Mary Ann Clibbery was bludgeoned to death with a hammer. Her business partner, George Hansen, was convicted of her murder the following year. Investigators found he had misappropriated more than $50,000 from the business the two shared. Before her death, Clibbery had told her doctor and a police officer she believed Hansen was trying to kill her, after an incident in which she was drugged with a sleep aid in her coffee.5Association of Certified Fraud Examiners.

Robert Petrick
Robert Petrick, already a convicted white-collar criminal, was found guilty of first-degree murder of his wife. Her body was recovered from water, wrapped in a tarp, sleeping bag, blankets, and chains. Prosecutors argued he killed her after she discovered both an affair and fraud in her bank account.5Association of Certified Fraud Examiners. When White-Collar Crime Turns Red, Part 1
Christopher Porco
In 2004, Christopher Porco had been using his father’s signature to fraudulently obtain student loans and make purchases. When his parents found out and confronted him by email, his father threatened to alert the bank. Seven days later, both parents were attacked with an ax while sleeping. Peter Porco died of his injuries. Joan Porco survived but suffered severe wounds and was left in a coma. Christopher Porco was convicted of second-degree murder and is serving 50 years in prison.5Association of Certified Fraud Examiners. When White-Collar Crime Turns Red, Part 1 The threat of exposure came from family, not an auditor or investigator.
How the Law Charges Red Collar Conduct
No criminal code lists “red collar crime” as an offense. Prosecutors instead stack charges that cover both the fraud and the violence used to conceal it, and federal law treats violence against witnesses and informants severely.
Under the federal witness tampering statute, killing someone to prevent testimony or cooperation with law enforcement carries the same punishment as murder under federal law, up to the death penalty or life imprisonment. Attempting to kill or using physical force against a person for the same purpose carries up to 30 years. Threatening physical violence to prevent testimony can bring up to 20 years.6Office of the Law Revision Counsel. 18 U.S. Code 1512 – Tampering With a Witness, Victim, or an Informant
A separate statute covers retaliation against people who have already given information to law enforcement. Killing a witness or informant in retaliation carries murder-level penalties, with attempted killing punishable by up to 30 years. Causing bodily injury, damaging property, or threatening either in retaliation can bring up to 20 years. If the retaliation stems from testimony in a criminal case, the maximum can be raised to match whatever the defendant faced in that underlying case, where that carries a higher penalty.7Office of the Law Revision Counsel. 18 USC 1513 – Retaliating Against a Witness, Victim, or an Informant
These charges run on top of the underlying fraud counts — wire fraud, mail fraud, securities fraud, embezzlement — and alongside any state murder or assault charges. The same series of events can be prosecuted in both federal and state court.
What Whistleblower Protections Do and Do Not Cover
If you work at a publicly traded company and report suspected financial fraud, the Sarbanes-Oxley Act prohibits the company and its agents from firing, demoting, suspending, threatening, harassing, or otherwise discriminating against you for reporting conduct you reasonably believe violates federal fraud statutes or SEC regulations. The protection applies when the report goes to a federal agency, a member of Congress, or a supervisor inside the company.8Whistleblower Protection Program. Sarbanes-Oxley Act (SOX)
The important limit for anyone worried about a red collar situation: Sarbanes-Oxley protects your job, not your safety. It addresses employment retaliation like firing or demotion. It was not written to address the physical risk a whistleblower may face from the person being reported. If a subject is showing the warning signs above — direct threats, intimidation, disproportionate anger — that is a matter for law enforcement, and the federal witness tampering and retaliation statutes exist for exactly that reason.
