Murdered/Unsolved: Darlene Hulse

It was mid August, 1984, when a young mother had to do the unthinkable...fend off an intruder that had the guise of a salesman. While her two young daughters bathed, Darlene fought the man who used her own fire poker against her. Panic ensued, and before long, authorities were at the home. But Darlene was not. Now, almost 40 years later, the case remains unsolved. However, can new DNA technology warm up this very cold case?
