A federal judge sentenced a Margate man to 25 years in prison for amassing an arsenal of weapons and developing detailed attack plans targeting Jewish and Black Americans throughout South Florida.
John Kevin Lapinski Jr., 41, received the 300-month sentence from U.S. District Judge Rodney Smith after pleading guilty to multiple federal firearms charges, including possession of weapons as a convicted felon and possession of an unregistered silencer.
The case unravelled on Halloween night 2024 when Margate Police responded to reports of gunfire in a residential neighbourhood. Officers identified Lapinski—who was legally prohibited from possessing firearms—as the shooter and discovered a chilling scene inside his home that revealed the scope of his racist ideology and violent intentions.
Arsenal and Attack Plans Uncovered
The search of Lapinski’s residence revealed a meticulously planned terrorist operation. Investigators found five firearms, more than 3,000 rounds of ammunition, two silencers, body armour, smoke grenades, a ghillie suit, and extensive tactical gear. Perhaps most disturbing was a shooting target depicting a Black male that had been “riddled with bullet holes,” according to court documents.
More alarming still were the detailed maps and planning materials that laid bare Lapinski’s racist motivations. Officers discovered maps of local schools, parks, and community sites defaced with racial slurs targeting Black and Jewish residents. A handwritten “target list” explicitly named “groups to attack” based on race and religion, including a Jewish member of Congress, local synagogues, Jewish-owned businesses, and other sites identified by the ethnicity or religion of their occupants.
Federal investigators connected Lapinski to an August 2024 shooting that targeted the home and vehicle of a Jewish resident, demonstrating that his plans had already progressed beyond preparation to active violence.
Swift Federal Response
“This defendant stockpiled weapons, tactical gear, and detailed attack plans to terrorise Jewish and Black Americans in our communities,” said U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida. “His intent was not abstract—it was written on his maps, his targets, and his so-called hit list.”
The prosecutor emphasised that federal law enforcement had disrupted the plot before it could escalate to mass violence. “Thanks to the swift work of our law enforcement partners, his plan never became reality. Instead of carrying out acts of racist violence, he will spend the next quarter-century behind bars.”
The case was investigated jointly by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the FBI, and the Margate Police Department, highlighting the coordinated federal response to domestic terrorism threats.
Warning to Other Extremists
Quiñones used the sentencing to send a clear message to other potential domestic terrorists: “Let this sentence serve as a warning: hate-fueled violence will be met with decisive federal prosecution. We will disrupt your plans, seize your weapons, and ensure you never endanger the people of this District again.”
The 25-year sentence reflects the serious federal penalties available for domestic terrorism cases, particularly when defendants accumulate multiple weapons charges while planning attacks against protected communities.
Lapinski’s case joins a growing number of federal prosecutions targeting individuals who stockpile weapons and develop attack plans motivated by racial and religious hatred, as federal authorities increasingly treat such cases as domestic terrorism requiring the strongest possible sentences.
