The Kansas City Star reports Manuel Garcia of Kansas City received the sentence on Monday. He pleaded guilty in the case in June.

Garcia admitted making three telephone calls to authorities in October 2013 about the fake plot to contaminate water supplies in Kansas City, St. Louis, Wichita and Topeka.

An FBI agent recognized Garcia’s voice from a 2010 case in which he was sentenced to 18 months in federal prison after pleading guilty to making a phone call threatening to bomb the U.S. courthouse in downtown Kansas City.
