Yesterday, Richard D. Hyerczyk, 54, of Chicago’s Garfield Ridge neighborhood, pleaded guilty in federal court that he mailed more than 90 threatening and/or harassing letters to Chicago police officers, other government and law enforcement officials, private individuals, schools, and religious institutions in the Chicago area between November 2003 and December 2012.
Hyerczyk pleaded guilty to mailing a letter on April 21, 2008, that threatened to kill Chicago Police Department officers and members of their families. That letter followed local news media reports on April 15, 2008, that Chicago police officers had shot and killed a cougar that was located on the city’s north side. He admitted that he drafted letters containing threats to kill and commit violence against CPD officers and members of their families.
Hyerczyk faces a maximum sentence of five years in prison and a $250,000 fine, and his plea agreement anticipates an advisory federal sentencing guideline range of 33 to 41 months in prison. U.S. District Judge Gary Feinerman set sentencing for April 11.
