Three “militiamen” were found guilty Wednesday of plotting to kill Somali refugees who lived in a Garden City, Kansas, apartment complex, according to The New York Times. Patrick Stein, Gavin Wright, and Curtis Allen all face life sentences. “These defendants conspired to build a bomb, blow up a building and murder every single man, woman and child inside,” federal prosecutor Tony Mattivi said in his closing statements. For months, an FBI agent went undercover with a militia group the trio allegedly belonged to, and obtained recordings from the members—who often called Muslims “cockroaches,” prosecutors said. The men started to obtain materials to make explosives, while recordings revealed that they planned “to detonate bombs at the apartment complex in November 2016,” according to prosecutors. They planned their attack to coincide with Muslim prayer times to maximize the amount of people injured and killed.
