JANESVILLE, Wis. — A Rock County man has been sentenced to 16 years in prison for homicide charges related to a 2024 crash, according to the Rock County District Attorney's Office.
Koty Diaz, 33, was convicted of two counts of homicide by intoxicated use of a motor vehicle earlier this week. The charges originated from an incident on Aug. 17, 2024, when Diaz, after leaving a local tavern, drove at high speed, crossed grass and a curb, and ran a red light on Beloit Ave. He collided with a Pontiac G6 on Delavan Dr., resulting in the deaths of the driver and his fiancée. Authorities reported that Diaz's blood alcohol concentration was .102 at the time of the crash.
Judge Barbara McCrory sentenced Diaz to 16 years in prison, followed by 10 years of extended supervision. The District Attorney's Office praised the Janesville Police Department and Wisconsin State Patrol for their investigative efforts. The office also acknowledged the emotional statements made by the sons of the deceased driver during the court proceedings.
