William Joseph “Billy O” Osterhaus, 64, of Seneca, Kansas, passed away unexpectedly at his home on Sunday, March 15, 2026.
Bill was born April 26, 1961, in Seneca, Kansas, to Joseph F. and Margaret A. (Graf) Osterhaus. He grew up in Seneca and attended Seneca Public Schools, graduating from Nemaha Valley High School with the Class of 1981.
Seneca was always home to Bill. In 1987, he began working for the City of Seneca, dedicating nearly 39 years of service to the community he loved. Through his work and daily efforts, he took great pride in helping keep Seneca looking its very best. Bill was looking forward to retiring this April and had plans to give back by helping with the Meals on Wheels program and attending more of the casino bingo games he enjoyed.
Known far and wide as “Billy O,” Bill was a familiar and colorful presence in the Seneca sports scene. If you attended local games, chances are you heard his voice. He served as a spirited commentator and enthusiastic supporter, especially devoted to girls’ sports including volleyball and basketball, as well as American Legion Baseball and Nemaha Central football and basketball. Being part of the school community and supporting its students brought him immense joy. Bill was a follower of the Kelly baseball and softball as he rarely missed a game.
Bill also volunteered his time with SCTV as a camera operator for sporting events, further showing his dedication to local athletics and community involvement.
He never met a stranger and could strike up a conversation with anyone. Those who knew him best will remember his kind heart and willingness to help others—whether lending a hand with yard work or stepping in wherever he was needed, often without being asked.
Bill was a member of the Sons of the American Legion and the Knights of Columbus.
He was preceded in death by his father, Joseph (March 8, 2008); his mother, Margaret (March 7, 2018); his brother, James (February 3, 1999); and his sister, JoAnn (April 27, 1974).
He is survived by several cousins and many dear friends throughout the Seneca community who will miss his voice, kindness, and unwavering support of his hometown.
A rosary will be at 2 P.M. on Sunday March 22, 2026 at the Lauer Funeral Home in Seneca. The Mass of Christian Burial will be held at 11:00 a.m. on Monday, March 23, 2026, at Sts. Peter and Paul Catholic Church in Seneca. Burial will follow at Sts. Peter and Paul Catholic Cemetery in Seneca, where he will rest beside his father and siblings.
Memorial contributions may be given, in lieu of flowers, to SCTV or the Nemaha Central Sports Program—organizations that reflect Bill’s love for his community and its young athletes.
