In September 1964, 50-year-old Catherine Bik Blackburn was sexually assaulted and murdered in her home on Colonie Street in Albany, New York.

Investigators collected a significant amount of evidence, including blood samples, a footprint in the yard, and slips of paper believed to be connected to the killer. Blackburn, a foreman at the Fuller Brush Company, rented out a room in her home and was separated from her husband, who was an Air Corps veteran working in Japan.
Investigators learned that Blackburn had recently cancelled newspaper ads to rent out the room and painted the rental unit the same weekend she was killed.

In 2023, the Albany Police Department, working with the FBI, submitted forensic evidence to Othram in The Woodlands, Texas to determine if advanced DNA testing could help identify the suspect. Othram scientists successfully developed a DNA extract from the provided evidence and then used Forensic-Grade Genome Sequencing to build a comprehensive DNA profile for the suspect. Once the profile was created, it was provided to the FBI’s forensic genetic genealogy team, who worked to develop new leads in the case using forensic genetic genealogy…
