Medical Detectives

In 1992, 22-year-old Dawn Bruce was brutally murdered in her Virginia apartment. The killer left very little evidence, but investigators did notice a blood smear on a pillow case that appeared to have been made by one of the killer's fingers. New technology enabled investigators to identify a fingerprint from the cloth surface of the pillow case. This gave police the means to apprehend Robert Douglas Knight, who killed Dawn Bruce in a senseless act of revenge.
