Threatening Telephone Calls Send Colorado Man to Federal Prison for Six Years

For Immediate Release
U.S. Attorney's Office, Northern District of Iowa
Called a Cedar Rapids Bank More than 40 times in Two Days and Made a False Report of a Fire at the Bank

A man who repeatedly threatened a Cedar Rapids bank, its employees, and other individuals from northern Iowa by telephone and text messages was sentenced today to six years in federal prison.

Carl William Stuber, IV, age 31, from Aurora, Colorado, received the prison term after a November 12, 2019 guilty plea to two counts of transmitting a threatening communication in interstate commerce. 

Information from a plea agreement and at sentencing showed that Stuber called a bank in Cedar Rapids more than forty times over a two-day period in October 2018.  During these calls, Stuber threatened to “Columbine” the bank, kill employees, and make false reports to police and fire departments.  Stuber taunted the bank, noting the bank was powerless to stop him as restraining orders would not work and law enforcement would not extradite him to Iowa.  Finally, Stuber falsely reported a fire at the bank, causing the Cedar Rapids Fire Department to respond to the bank.  Stuber continued to make threatening calls to the bank and threatened others by phone, text, and Facebook message over an eight-month period until his arrest in Colorado in June 2019 on federal charges. 

Stuber was sentenced in Cedar Rapids by United States District Court Judge C.J. Williams.  In sentencing Stuber to 72 months’ imprisonment and a fine of $7,500, Judge Williams noted that Stuber’s threatening communications caused mental and psychological harm to the bank employees.  Stuber must also serve a three-year term of supervised release after the prison term.  There is no parole in the federal system.

The case was prosecuted by Assistant United States Attorney Kyndra Lundquist and investigated by the Federal Bureau of Investigation Joint Terrorism Task Force.
