Note - before purchasing this book, you may want to consider "Cold Cases of Stearns County, Minnesoata" instead. That book includes a condensed and updated version of "Tragedy on The Prairie" as well as "Two Sisters Missing." On May 13, 1976, a bomb exploded in the Kimball Post Office, killing assistant postmaster Ivend Holen. As of the 40th anniversary of the bomb, in 2016, the case remains an unsolved mystery. The purpose of this book is to tell the story of the bomb tragedy in the hopes that information contained herein may one day help solve the case, and also so that people remember Ivend Holen for the man that he was and all the good that he did for the town of Kimball, Minnesota. Holen was a key part of the Kimball community. He had lived in the area for the last fourteen years, after moving there in 1962 from Minneapolis where he also worked as a postal worker in Robinsdale and Minneapolis. He commuted from Kimball to the Minneapolis area for about eight years, finally transferring to a lower paying job as a post office clerk in Kimball in 1969. He was later promoted to assistant postmaster at the Kimball Post Office. Ivend was actively involved in his family's church, St. John's Lutheran Church. He had served on the local school board and was a member of the American Legion Post in Kimball and the Sons of Norway. He was also known for the significant amount of volunteer work he did for the young people in town. Everyone who knew Ivend Holen was quick to point out that he always had a smile for everyone he saw. He would give a friendly greeting to all he came across during a typical day. When children wrote letters to Santa Claus at Christmas time, it was Ivend Holen who would answer those letters, writing back to the children as if he were Santa himself. Ivend and his large family lived on a modest forty-acre hobby farm about three miles south of Kimball. He was well known for his gardening prowess and also as a beekeeper. He utilized his gardening experience and influence in town to assist the Kimball High School in building a greenhouse for its students to utilize. He wanted the younger generations to have the tools available to learn how to grow vegetables and flowers for themselves. The sudden and shocking act of violence that had befallen the town of Kimball shredded the peaceful and easy-going way of life that residents of the rural farming town had grown accustomed to for decades. Kimball was a place where practically everyone knew each other and no one seemed to have enemies. Gone was the blanket of security that had covered the town for so long, shattered in an instant by what seemed to be a random stroke of violence.
