End of Watch: July 3, 1992
Sgt. Zesiger was leading a family to a campsite near McNary when his fully-marked departmental Chevrolet Blazer was struck head-on by a pickup truck driven by Calvin Dayea, who was found to be driving under the influence. In April 1993, Dayea was sentenced to four years in a federal prison but was released Dec. 21, 1994. Ten days later, Dec. 31, 1994, he was arrested by a DPS officer following a short pursuit on the Navajo Reservation. Dayea was found to be in violation of his parole (drinking alcoholic beverages) and was returned to a federal prison to complete his term.
