For Immediate Release
U.S. Attorney's Office, Northern District of Iowa
Passed Notes to Teller Threatening to Blow-Up the Bank

A man who attempted to rob the Freedom Bank in Monona, Iowa, was sentenced today to 3 years in federal prison.

Tyler Koehler, age 21, from Monona, Iowa, received the prison term after a November 16, 2017 guilty plea to attempted bank robbery.

At the guilty plea, Koehler admitted he attempted to rob the Freedom Bank in Monona on June 9, 2017.  Information presented at his sentencing hearing showed that Koehler passed multiple notes to the teller at the bank’s drive-up window.  Each note threatened to “blow this place up” unless the teller gave Koehler cash.  The third note Koehler passed demanded $100,000.  The teller stalled him until police arrived and took him into custody.  Koehler has multiple prior convictions for disorderly conduct in Wisconsin and Georgia. 

Koehler was sentenced in Cedar Rapids by United States District Court Judge Linda R. Reade.  Koehler was sentenced to 36 months’ imprisonment.  He must also serve a 3-year term of supervised release after the prison term.  There is no parole in the federal system. Koehler is being held in the United States Marshal’s custody until he can be transported to a federal prison.

The case was prosecuted by Assistant United States Attorney Anthony Morfitt and investigated by the Federal Bureau of Investigation, the Monona Police Department, and the Clayton County Sheriff’s Office.
