Summary based on the NamUs case record (MP96453) and 1 other source
In the winter of 1990, a 38-year-old woman named Susan Brenda Kardas vanished from Snoqualmie, Washington. She was last seen on December 16th of that year. At the time of her disappearance, Susan was described as a Caucasian female with brown hair and blue eyes, standing at 5 feet 7 inches tall and weighing around 92 pounds. The circumstances surrounding her last known moments are connected to the powerful and scenic Snoqualmie Falls.

The official narrative provided by law enforcement suggests a deeply concerning possibility for what transpired. The prevailing belief is that Susan may have jumped from Snoqualmie Falls. This theory points to a tragic and sudden end, leaving little room for alternative explanations in the initial stages of the investigation. The Kirkland Police Department is the primary agency handling her case, which is documented under the agency case number 90K7504.

Years have passed since Susan Kardas was last seen, and her case has grown cold, yet she is not forgotten. Information about her disappearance has been entered into the National Missing and Unidentified Persons System under case number MP96453. This national database serves as a crucial tool for law enforcement and the public, keeping the memory of the missing alive and facilitating the potential for new leads. The overview of Susan's case is one of profound sadness, centered on the belief that she tragically ended her own life at a local landmark. Despite the passage of time, her case remains open, a lingering question in the history of King County.

Last Seen: Dec 16, 1990
