Shirley Leona Sprang was 61 when the last official trace of her was recorded on December 19, 1996, following an interaction with law enforcement in Lincoln, Nebraska. The circumstances of that encounter and why she was in Nebraska are not described, and no confirmed information about her whereabouts has been reported since.

Shirley’s disappearance began on June 16, 1990, in Two Rivers, Wisconsin, when she left home after a disagreement with her mother and took a taxi. She was described as a white female, between 5 feet 0 inches and 5 feet 7 inches tall, 120 to 160 pounds, with blonde or strawberry-blonde hair, blue eyes, and possible scarring on both arms from psoriasis. The Manitowoc County Sheriff’s Department is handling the investigation.

If anyone knew Shirley, saw her after June 16, 1990, or has information about her time in Nebraska in 1996, please come forward with what you remember.
