Devices were found inside his front pocket and a backpack he was carrying on the scene, in addition to a tent encampment set up in close proximity to the cathedral, the records show.

A man arrested outside the annual Red Mass ceremony held at St. Matthew’s Cathedral had over 200 explosive devices in a tent on the church’s stairs, according to police. 

Louis Geri, 41, touted homemade explosives when officers approached him on the step ahead of the service typically attended by Supreme Court justices to ring in a new term, according to court records reviewed by the Washington Post.

Authorities also found vials of nitromethane, a colorless, organic compound used in explosive devices, the court records showed.

Geri said he had a background in explosives and told officers at the scene that the vials were intended to be used as grenades with rubber bands to secure the fuse, according to court records, per the Post.
