Suspect in 1983 homicide identified through genealogy

Wednesday, February 22, 2023 – In early 2022, Season of Justice funded advanced DNA analysis and Forensic Genetic Genealogy for Livingston Co. Sheriff’s Department (Howell, MI) in the 1983 unsolved homicide of 19-year-old Christina Castiglione. Thanks to the dedicated work of Livingston Co. investigators and analysts at Othram Labs, Christina’s killer has been identified as Charles David Shaw. Shaw passed away nearly 8 months after Christina’s murder, but with the use of Forensic Genetic Genealogy and cooperation from Shaw’s living relatives, investigators were able to confirm Shaw’s involvement. We want to extend our gratitude to the Livingston Co. Sheriff’s Department, their volunteer cold case unit, and Othram Labs for their hard work bringing this nearly 40-year-old case to a close. We hope this brings peace to the Castiglione family.
