The “Andy” Files: The Full Dossier on Anthony Kazmierczak

Date: January 28, 2026

The Narrative: A Dual Life

To the residents of the quiet 55419 zip code in Minneapolis, 55-year-old Anthony Kazmierczak was a physically declining figure—a man battling Parkinson’s disease and chronic spinal pain who needed help watching his dog. But to the FBI, who officially took control of the investigation this morning, he is the primary suspect in a federal assault case targeting a sitting member of Congress.

We have now combined the raw data from his background report with breaking updates from federal investigators to build the most complete profile available. The picture that emerges is of a man whose life was collapsing on every front—financial, legal, and physical—before he decided to lash out.

Here is the exhaustive profile of the man behind the attack.

I. The Attack: Escalation to Federal Case

The investigation has shifted from a local assault charge to a federal probe.

• Federal Takeover: The FBI has officially taken the lead in the investigation, signaling that prosecutors are likely pursuing federal charges for assaulting a government official [1].

• The Weapon: Forensic teams are analyzing the “amber-colored” liquid found in the syringe. Witnesses and onsite journalists consistently describe a “strong, vinegar-like smell” [2].

• The Demand: As he rushed the stage, Kazmierczak did not just scream; he shouted a specific political demand at Rep. Omar: “You must resign!” [3].

II. The “Andy” Manifesto: Specific Radicalization

We have now uncovered the specific content of the “Andy” social media profiles linked to Kazmierczak’s verified email (andykazmierczak@hotmail.com). His radicalization went far beyond general grievance.

• The “Slave Restitution” Post: In one specific post found by investigators, Kazmierczak wrote: “When will descendants of slaves pay restitution to Union soldiers families for freeing them/dying for them, and not sending them back to Africa?” [4].

• The Trump/Kirk Connection: Following the assassination of Charlie Kirk in September 2025, reports indicate he deepened his alignment with reactionary politics, changing his profile picture to Donald Trump and frequently sharing content that echoed hardline stances [5].

• Local Targets: His grievance was local, too. He previously posted attacks on Minneapolis Mayor Jacob Frey, who was seated next to Omar during the attack, criticizing him for not cooperating with federal agencies.

III. Criminal History: A Lifetime of “Anomalies”

Kazmierczak’s record is not just long; it is chaotic. The background report reveals a history of “duplicate” charges and jurisdictional confusion.

• 1989 (Felony Auto Theft): His record begins with a felony conviction at age 19 [6].

• 2009 (The St. Anthony Misdemeanor): Charged with “OTHER COUNTY/GM & MISD” (Gross Misdemeanor), resulting in a $550 fine.

• 2011–2012 (The DWI Duplicate): A single case (#0112174-FC) appears twice in his records with conflicting outcomes:

  • Washington County: Arrested by Forest Lake PD. Sentenced to 3 years probation.

  • Hennepin County: Arrested by Airport PD. The same case resulted in a harsher 5-year probation term.

IV. Financial Ruin & “Ghost” Assets

Kazmierczak filed for Chapter 7 Bankruptcy (Case #1940266) in Minneapolis, declaring insolvency. However, his asset schedule lists a fleet of aging luxury vehicles, suggesting a man clinging to past status:

• 1984 Lincoln Continental (VIN: ...680742)

• 1992 Mercedes Benz 300 (VIN: ...208897)

• 1992 BMW 3 Series (VIN: ...05717)
