Dubuque, Iowa — Jacob Carl Schmitz, 40, was arrested on Friday, May 8, 2026, at 5:17 p.m. on a charge of felony probation violation.

Officers took Schmitz into custody at 770 Iowa Street, the address of the Dubuque Law Enforcement Center, according to the official daily bulletin. The case number is 2026001250. Booking records also list a related misdemeanor charge: Defraud Drug/Alcohol Test – Use Urine of Another Person. Officer T.C. Griner is listed as the arresting officer.

Criminal History

Schmitz has a well-documented history in the Dubuque County court system. Key prior cases include:

•  2018: Pleaded guilty to two counts of second-degree theft, both class D felonies. He received consecutive prison sentences, which the Iowa Court of Appeals upheld in February 2020 (Case 18-1776).

•  2022: Arrested following an incident at Q Casino, where he allegedly threatened people by accelerating his vehicle toward them and displaying a knife. Charges included intimidation with a dangerous weapon, assault, interference with official acts, driving under suspension, and a parole violation.

•  2025: Arrested in May on a warrant for second-degree theft and forgery. Court records also show a sentenced commitment (mittimus) issued on December 30, 2025.

The current probation violation charge likely stems from failure to comply with conditions of supervision from one of these earlier felony convictions. In Iowa, typical probation conditions include regular reporting to a probation officer, passing drug and alcohol tests, maintaining employment, and avoiding new law violations. Breaking these conditions can lead to revocation and possible imprisonment.
