Wilmington, NC - Jack R. Criss, age 79, passed peacefully on July 17, 2026, following a courageous battle with cancer. He is survived by his daughter Jennifer (Craig) Baker and son Nat (Megan) Criss. He is also survived by his brother Mark (Cara Dugan) Criss and partner Linda Boos. He was preceded in death by his parents Ralph ("Bud") and Virginia Criss and nephew Ben. A Pittsburgh sports fan through and through, he passed that devotion on to his children and grandchildren (with a few exceptions).
