Investigators found white supremacist propaganda, bomb-making materials and a framed photograph of Oklahoma City bomber Timothy McVeigh at a Florida apartment where a teenager killed two roommates who had once shared his neo-Nazi beliefs before he converted to Islam, police and the FBI said.
Devon Arthurs, 18, led police to the two bodies inside his Tampa apartment last Friday, saying he killed them after they showed disrespect for his new faith, according to police and FBI reports released Monday.
A fourth roommate, a member of the Florida National Guard, was arrested on charges related to the alleged discovery of bomb-making materials.
The investigation began unfolding Friday, when Arthurs held two customers and an employee hostage at gunpoint at a Tampa smoke shop, police said.
Arthurs said he converted to Islam and was upset about American bombings in Muslim countries, among other issues, according to a Tampa police report. He is being charged with two counts of first-degree murder and other charges, and court records did not list an attorney for him.
