Shirley Leona Sprang, 61 when last seen, vanished from contact more than two decades ago. The final confirmed sighting was on December 19, 1996, when she had contact with law enforcement in Lincoln, Nebraska. Her family’s last contact with her, however, dates back to June 16, 1990, when she left her Two Rivers, Wisconsin, home after an argument with her mother and took a taxi; there has been no word from her since.

Shirley is described as a white woman between 5 feet 0 inches and 5 feet 7 inches tall, weighing 120 to 160 pounds, with blonde or strawberry-colored hair and blue eyes. She may have had scarring on her arms from psoriasis. The Manitowoc County Sheriff’s Office continues to investigate; the case is listed in NamUs and other missing person databases but has produced no significant leads.

Did anyone in Two Rivers, Lincoln, or along likely travel routes remember seeing Shirley or her taxi around 1990 through 1996?
