Warrens man convicted of vehicular homicide

Yancy Dieter

SPARTA, Wis. (WKBT) — A Warrens man was convicted Wednesday four different charges stemming from a 2017 fatal car crash.

Yancy K. Dieter, 48, was convicted of one count of reckless homicide, one count of homicide by intoxicated use of a vehicle, one count of homicide by use of a vehicle with a prohibited alcohol concentration, one count of knowingly operating a motor vehicle while revoked causing death, and one count of failure to install an ignition interlock device, according to the Monroe County District Attorney’s Office.

Dieter was driving at 120 mph while drunk when his vehicle went off the road and crashed, killing his passenger, according to records. A sample of Dieter’s blood, taken several hours after the wreck, showed a blood alcohol concentration of .192.

After four days of trial the jury deliberated for just over three hours before reaching their verdicts.

“The jury’s verdicts send a strong message that the citizens of Monroe County will not tolerate anyone endangering the lives of others by intoxicated use of a motor vehicle,” said DA Kevin Croninger said in a press release. “Mr. Dieter engaged in extremely dangerous and reckless behavior in 2017 which caused the death of the victim. I am grateful the jury took the time, considered the evidence in full and delivered a verdict that provides justice to the victim and his family.”

The prosecution was led by Assistant District Attorney Sarah Skiles. Croninger praised her work on the case.

“She has provided an extremely high level of service to the people of Monroe County for more than five years and her immense skill as a prosecutor and litigator were on full display throughout this matter both before and at trial,” he said.

Dieter will be sentenced in April by Monroe County Circuit Court Judge Richard Radcliffe.
