Deputy Jamie Tlachac proved through his actions that a 2008 incident in which he shot off a gun in his house was an isolated one, the Kewaunee County Sheriff’s Department said Wednesday.

Tlachac, 42, was identified Tuesday as the officer who fire the fatal shot in a confrontation with a man authorities say was threatening a woman and several nearby residents along County Road AB on Aug. 21.

He was a jailer and dispatcher in August 2008 when, court records say, he came home from a night of heavy drinking, picked up a rifle and fired two shots toward the rear patio door of his home in Luxemburg. No one else was home at the time.

Sheriff Matt Joski asked the Manitowoc County Sheriff’s Department to investigate the case to assure impartiality, and in December of that year, he was charged with second-degree reckless endangerment, a felony, and misdemeanor counts of going armed with a firearm while intoxicated and disorderly conduct.

In May 2009 Tlachac pleaded no contest to the misdemeanors and was sentenced to two years on probation, with a 60-day jail term that would have been served if he violated the conditions, which included absolute sobriety. He also lost his job with the department.

After three years as a volunteer firefighter and serving with another agency, Tlachac was rehired as a deputy and has been a member of the patrol division since 2015.

In a news release reported by WLUK-TV, the department said the decision to rehire Tlachac was based on his continued service and ability to show that the 2008 incident was isolated.

“Since his rehiring, there have been no further disciplinary actions and he has served as the Tactical Medical Technician for the Kewaunee County Emergency Response Unit, as well as as the agency’s CPR Instructor,” the release said.

The state Division of Criminal Investigation continues to probe the Aug. 21 incident.
