Violence in the United States has been making headlines in ways that feel both shocking and familiar.
Two recent high-profile attacks—one involving Charlie Kirk and another the alleged murder of United Healthcare CEO Brian Thompson—highlight striking similarities that law enforcement cannot ignore.
As a former FBI Supervisory Special Agent with 21 years on the job, including the Boston bombers case, I’ve seen firsthand how certain acts of violence are methodically planned.
These aren’t random outbursts—they’re messages in motion.
Messages Hidden in Plain Sight
One of the most chilling details in both cases is the apparent writing on ammunition.
When Thompson was killed, investigators discovered words like “Deny,” “Defend,” and “Depose” etched into the shell casings, echoing the insurance industry mantra “Delay, Deny, Defend.”
In Kirk’s case, authorities reportedly found similar markings on unused cartridges, with phrases described initially as “transgender and anti-fascist.”
One message read, “Catch a fascist,” suggesting the shooter intended not just to commit violence but to weaponize a narrative. Understanding these messages is as crucial for investigators as tracking down the suspect.
Profiling the Perpetrators
Both alleged shooters share more than just their messages.
Mangione, accused of killing Thompson, was 26 at the time; Tyler Robinson, Kirk’s suspected killer, is 22.
Both targeted a single individual, dressed in black, and showed a high level of organization that allowed them to evade capture for some time.
This is what law enforcement calls the Pathway to Violence—a methodical progression from grievance to premeditated attack.
Often, there’s “leakage,” where the perpetrator shares their thoughts online or with someone in person before acting, leaving digital footprints investigators can follow.
The Role of Family and Public Tips in Capturing Suspects
In both cases, family played a critical role. Robinson’s arrest came shortly after a family member contacted authorities.
Similarly, Mangione was located after a tip from his mother and a public sighting at a McDonald’s.
The public’s assistance is invaluable. Tip lines flood with calls, and every credible lead is logged and cross-checked with investigative evidence.
This collaboration between law enforcement and the community often accelerates the resolution of complex cases.
The Dual Nature of Investigations
Investigators work on two fronts: the manhunt and the forensic analysis.
On the forensic side, officers meticulously process the crime scene, collecting shell casings, fingerprints, DNA, and surveillance footage.
Even a cigarette butt or a smudge can provide a breakthrough.
Ballistics experts match shell casings to weapons, and analysts cross-check prints and DNA against national databases.
Meanwhile, the manhunt is rapid and relentless. Fugitive squads scour neighborhoods, relatives’ homes, former workplaces, and public areas.
Tactical teams and advanced surveillance technology—from helicopters with infrared cameras to highway license plate readers—ensure that every lead is pursued immediately.
Building the Shooter’s Profile
Investigators also focus on profiling the suspect, compiling every available piece of information: criminal history, addresses, family connections, phone records, social media activity, and financial transactions.
Symbolic writings on ammunition suggest a preparation for a final confrontation, tightening timelines and increasing urgency.
The Outcome of a Manhunt
Manhunts typically end in one of three ways: the suspect surrenders, is captured by tactical teams, or is confronted forcibly.
In this case, authorities managed to apprehend Robinson quickly, ending the immediate threat and bringing the investigation into the next phase: building a solid case for prosecution.
Understanding Narrative-Driven Violence
Both incidents remind us that targeted attacks often carry a psychological and ideological component.
The writings, the careful planning, and the messaging all point to perpetrators attempting to influence the story surrounding their crimes.
For law enforcement, dissecting these motives is crucial to preventing future attacks and ensuring public safety.
