It is with deep sorrow that we announce the passing of Khamkong Xayavong, better known to his friends as KK, beloved husband, father, brother, uncle, and friend, who took his last breath on February 11, 2026, at 12:54 AM. Born on May 25, 1955, in Laos to Kham and Phat Xayavong, KK touched the lives of many and will be profoundly missed.

KK married his loving wife, Osay, in October 1978. Together, they welcomed their first child, Somphong Tiou Xayavong, on August 2, 1979, in Bangkok, Thailand. In January 1980, KK immigrated to the United States. They first arrived in Philadelphia, PA, and then quickly made their way to Albuquerque, NM, to meet up with his younger sister, Sounthone (Nang). In 1982, they moved to Grand Island, Nebraska, where they both worked at Monfort. Their family grew with the addition of their second child, Michael Xayavong, born on September 22, 1982. In 1987, they relocated to Sioux Falls, South Dakota, where KK enjoyed playing pool, bowling, performing with his band Noom Sy Khout, and having friends over for dinner. He became a naturalized citizen of the United States on May 12, 2006. He was employed at John Morrell from 1987 until his retirement in 2021.

KK was known for his dedication to his family and his kind, mischievous spirit. He is survived by his beloved wife, Osay Xayavong; his son, Tiou Xayavong, and daughter-in-law, Ava (Noui) Senaphan; his sisters, Keoouthong Xayavong and Sounthone (Nang) Hansana; his brothers-in-law, Bounleth Hansana and Vira Doungchampa, and sister-in-law, Bounnhou Doungchampa; and his cherished nephews and niece, Peter, Sovanna, and Peterson Xayavong, Island Joe and Ketsamon Hansana, Jack and Francis Doungchampa. He leaves behind his treasured granddaughters, Naudia, Janessa, Khamsavanh, and Asuna Xayavong, and grandsons, Poet and Kinryu Xayavong, Jovi and Shayden Khao-On.

KK's warmth, love, and laughter will forever remain in the hearts of those who knew him.
