Federal authorities investigating a terror plot against Muslim immigrants in Garden City, Kansas, have allegedly discovered a large collection of child pornography in the home of one of the suspects, the Kansas City Star reported Tuesday.

Patrick Eugene Stein, Gavin Wayne Wright, and Curtis Wayne Allen were charged with domestic terrorism in mid-October for their alleged plan to bomb a local mosque and housing complex home to much of the town’s Somali Muslim population.

After obtaining search warrants for the three men’s homes, authorities allegedly discovered two images on USB drives belonging to Stein that depicted pre-pubescent girls in sexually graphic poses, according to documents filed in federal court in Kansas City and reviewed by the Star.

Authorities then obtained a federal search warrant to search Stein’s computer equipment for additional underage pornography, and allegedly obtained some 250 still images and two videos of “child pornography/child erotica,” according to the Star.

No additional charges have been filed as a result of this new investigation, the Star reported.

All three men face one count of conspiracy to use a weapon of mass destruction.

The suspects allegedly have ties to an extremist, hard-right militia movement known as the “Crusaders” and bragged to undercover agents about their plans to murder Muslim Somalis.
