SIOUX FALLS, S.D. (KELO.com) -- Bomb-making materials have been found at the apartment of a burglary suspect in Sioux Falls.
"...identified as ammonium nitrate and aluminum powder mixed together, which that compound, there is no legal purpose for it. It is an explosive." says Captain Jason Gearman with the Minnehaha County Sheriff's Department.
Gearman says they also found an 'Antifa' coat and indications of extreme hatred for the police, fire and the government, and an improvised explosive device in the suspect's vehicle. Also, some illegal firearms.
"Pretty safe to say that we stopped something from happening. Again, we don't know what that is."
Mark Christopher Einerwold, 43, is jailed on burglary charges, but is expected to soon be charged in connection with the explosive materials.
Authorities had warrants to search at 1112 S. Blaine Ave because of the burglaries in Dell Rapids and Tea and that's when they made their grimmer discovery.
Antifa is an extreme left wing and anarchist group that uses direct action and often violent means to protest what it calls right wing and fascist organizations and ideas.
