Colorado man sent to 6 years in prison for threatening to 'go Columbine' at Cedar Rapids bank

He was angry over getting access to his trust fund

CEDAR RAPIDS — A Colorado man was sentenced Monday to six years in federal prison for threatening to kill bank employees — to “go Columbine” — and making false reports to police and fire departments because he was upset about getting access to money in a trust fund.

Carl W. Stuber IV, 31, of Aurora, pleaded guilty in U.S. District Court on Nov. 12 to two counts of transmitting a threatening communication in interstate commerce.

A plea agreement and sentencing documents show Stuber called a Cedar Rapids bank more than 40 times over a two-day period in October 2018. He was upset about getting access to money to use in court cases in Georgia or Colorado.

During these calls, Stuber threatened to come to Iowa and “go Columbine” on the bank, kill employees and make false reports to police and fire departments. He said “people are gonna” die if he didn’t get his money, according to court documents.

Stuber taunted the bank, noting the bank was powerless to stop him since restraining orders would not work and law enforcement would not extradite him to Iowa. He also falsely reported a fire at the bank, causing the Cedar Rapids Fire Department to respond.

The Columbine reference is to the April 20, 1999, school shooting at Columbine High School in Columbine, Colo., where two students murdered 12 students and one teacher.

In response to Stuber’s behavior, the Cedar Rapids bank hired a “victim specialist” to give a presentation to employees, particularly those who had spoken with Stuber. The bank also installed a system to route some of his calls to voicemail and record them.


On Nov. 14, 2018, Stuber called his lawyer in Colorado wanting his retainer money back, threatening to “make everyone famous and they would end up on the news,” according to sentencing documents. The lawyer locked his office for security.

Stuber continued to make threatening calls to the bank and threatened others by phone, text and Facebook message over an eight-month period until he was arrested in Colorado in June 2019 on federal charges, according to court documents.

During this time, he also sent 26 threatening text messages to his father and 30 Facebook messages to his mother. In those messages, he sent two photos of two dogs he had arranged to make it look like he had killed them — using ketchup on the dogs and including a knife in the photo, sentencing documents show.

Stuber’s criminal history includes convictions for theft, probation violations, manufacturing and selling marijuana, assault causing bodily injury, domestic abuse and violation of a family violence order.

He has pending charges in Colorado and Georgia, including assault and making threats, according to court documents. He s accused of choking a person and then failing to appear in court. On Sept. 21, 2018, he was charged with felony menacing and violation of a protection order.

U.S. District Judge C.J. Williams also ordered Stuber to pay a fine of $7,500 and $4,985 for costs of prosecution. He must also serve three years of supervised release following prison.

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