William E. Mierzejewski, age 80, entered eternal rest on October 3, 2026, at the St. Raphael Campus of Yale New Haven Hospital, with his loving family by his side.
Born in Derby on November 12, 1945, he was the son of the late Walter and Mary (Siemienczuk) Mierzejewski.

A proud veteran, he honorably served his country in the United States Marine Corp in Vietnam where he earned the rank of Corporal. He happily volunteered his time at the West Haven VA Medical Center and also at the New Haven Soup Kitchen.
