William "Liam" Harry Cook, 46, passed away unexpectedly on October 1, 2021 at his home in St. Paul, MN; the cause of his death has not yet been determined. He is survived by his father and step-mother, Dayton and Annette Cook of Aberdeen, SD, sisters Sheri (Ken) Beck of Minneapolis and Cindy (Simon) DeRuyter of St. Paul, and nephews Daniel DeRuyter, Jonah Beck, and Toby Beck. Liam was born in Aberdeen, SD on June 24, 1975 and graduated from Aberdeen Central in 1993. Known as Billy to his friends and family until he was in his mid-twenties, Liam was passionate about skateboarding even before skateboarding became popular. He would work tirelessly to perfect skateboarding tricks and was considered a local skating legend of sorts. He lived and worked in various locations over the years, including Sioux Falls, SD; Minneapolis, MN; Lincoln, NE; Butte, MT; Kalispell, MT; and Aberdeen, SD, before moving to St. Paul in 2017. A cat lover and a fan of science fiction and post-apocalyptic films and TV, Liam also appreciated classic literature and poetry. He loved sharing his favorite books, shows, music, and memes with his friends. Liam struck up friendships with ease, and his quick wit and unique sense of humor will be sorely missed by all who knew him. Liam was preceded in death by his maternal and paternal grandparents and by his mother, Helen McLaughlin. A memorial service will be held on Saturday, October 9, 2021 at 3:00 PM at Robbinsdale Parkway United Church of Christ, 4200 Lake Rd., Robbinsdale, MN 55422. In addition, an informal (casual attire) celebration of his life will take place on Sunday, October 17, 2021 at 3:00 PM at the fellowship hall adjacent to the Spitzer-Miller Funeral Home, 1111 S. Main St., Aberdeen, SD 57401. In lieu of flowers, Liam’s family asks you to please consider a donation to NAMI – the National Alliance on Mental Health (nami.org) or to an animal rescue organization.
