In 1994, Shirley Duguay of Prince Edward Island, Canada went missing and was later found dead in a shallow grave. Among the most compelling pieces of evidence in the case was a leather jacket covered in Duguay's blood and over two dozen white feline hairs. The tests revealed that the hairs did come from the cat; Beamish was subsequently convicted for the murder of his wife. The forensic science of testing cat and dog hairs has been firmly established and studied, but it was an unknown science until the Duguay case.
