Would-be attacker of DC Red Mass targeted Catholics, police say

Washington, D.C. Newsroom, Oct 8, 2025 / 15:45 pm (CNA).

Police said the man arrested outside of a Washington, D.C., cathedral Oct. 5 had hundreds of explosives and papers suggesting he planned to target Catholics and Supreme Court justices. 

Louis Geri was arrested outside of the Cathedral of St. Matthew the Apostle before the annual “Red Mass” that welcomes Supreme Court justices and lawmakers. Police reported Geri had potential explosives on his person and in his tent set up near the church’s entrance.

When police approached him in the tent, he told police: “You might want to stay back and call the federales, I have explosives/bombs,” court documents show.

Police officers and the bomb squad conducted a further search and said they found Geri had paperwork that “revealed his significant animosity towards the Catholic Church, members of the Jewish faith, members of SCOTUS, and ICE/ICE facilities.” The search also “revealed a large cache of handmade destructive devices recovered from [his] tent,” police said. 

Geri also threatened to throw an explosive into the street and said he had “a hundred plus of them,” police said.

Papers found in Geri’s tent were titled: “Written Negotiations for the Avoidance of Destruction of Property via Detonation of Explosives,” police said. The suspect confirmed to police they were his papers. 

A business manager for St. Matthew’s provided police with paperwork showing the Metropolitan Police Department barred him from the location and that Geri had earlier been at the cathedral Sept. 26 when he had set up his tent on the steps and refused to leave.

Police said Geri told them: “Several of your people are gonna die from one of these,” referring to the explosives. 

Geri was charged with unlawful entry; manufacture, transfer, use, possession, or transportation of molotov cocktails or other explosives for unlawful purposes; threats to kidnap or injure a person; assault on police officer; possession of destructive device; manufacture or possession of weapon of mass destruction (hate crime); and resisting arrest. He is being held in jail without bond.
