Forensic Services for Medical Examiner and Coroner Offices Webinar Series – Webinar #2: Postmortem Testing

Facilitated by the Forensics TTA Team, this webinar features guest speakers Dr. Glenn Sandberg of Forensic Neuropathology Consultants, Dr. Emily Duncanson of Jesse E. Edwards Registry of Cardiovascular Disease, and Dr. Laura Knight of the Washoe County Regional Medical Examiner’s Office. The presenters highlight the various ways medical examiner/coroner (ME/C) offices of various sizes access postmortem testing services and specialists – including benefits and limitations of each. The presenters discuss working with neuropathologists, cardiac pathologists, and genetic testing, providing tips on how to best work with these different specialists, across their capabilities and how to get the full benefits of their services. This is the second session in a three-part series that provides a high-level overview of ancillary services that ME/C offices may interact with to investigate cases, focusing especially on more unusual cases.

DNA leads to suspect in 1998 rape and killing of nurse at Maryland hospital

Nearly three decades after the 1998 rape and murder of 50-year-old nurse, Sherry Crandell, the Prince George’s County Police Department announced the case has been solved. Crandell was found tied up, raped, and strangled in her office at the former Prince George’s County Medical Center in Cheverly, Maryland. Despite an extensive investigation, no arrests were made at the time. In December 2021, investigators revisited preserved DNA evidence and obtained a warrant to analyze it using Forensic Genetic Genealogy (FGG). With assistance from the Federal Bureau of Investigation’s Baltimore Investigative Genetic Genealogy Team, police identified Edward Watts, also known as Baari Shabazz, as the suspect in late 2025. Watts died in 2019, so no charges can be filed. The investigation was supported by Bureau of Justice Assistance Prosecuting Cold Cases Using DNA (COLD) Program grants awarded to the Prince George’s County State’s Attorney’s Office and the Prince George’s County Police Department to expand FGG testing in cold cases.

Advanced forensic analysis brings long-awaited answers in 2007 Rhode Island homicide

Eighteen years after Cynthia McKenna was found murdered in her North Providence apartment, Rhode Island authorities delivered definitive answers in a case that had long haunted her family. On February 21, 2007, McKenna was discovered unresponsive in her bed, and the state medical examiner later determined she died from asphyxiation caused by blocked airways. Despite early investigative efforts and the emergence of a prime suspect, the case stalled due to limited forensic capabilities. In 2024, using funding from BJA’s Prosecuting Cold Cases Using DNA (COLD) Program, the Rhode Island Attorney General’s Cold Case Unit reopened the investigation, applying modern forensic tools and a comprehensive re‑examination of evidence. Investigators re-evaluated confession letters written shortly after the murder and employed advanced DNA analysis, including Y‑STR testing, on biological material recovered from an envelope. The testing linked the DNA to a direct male relative of the suspect, helping to confirm authorship of the letters and corroborating witness statements and investigative findings. Based on the totality of the evidence—including forensic analysis, confirmed confessions, witness testimony, and gaps in the suspect’s alibi—the Cold Case Unit concluded beyond a reasonable doubt that Robert J. Corry, Jr. murdered Cynthia McKenna. Although Corry died in 2014 and criminal charges could not be filed, the findings brought long‑overdue clarity and resolution to McKenna’s family and formally closed the case. By combining advanced DNA technology with meticulous investigative review, the Rhode Island Attorney General’s Cold Case Unit demonstrated that even long‑dormant cases can reach meaningful resolution—affirming that the pursuit of justice does not end with time, and that answers remain possible years after a crime occurs.

Boston Police launch website seeking public assistance to reignite unsolved homicide investigations dating back to 1963

In a bold step to advance justice for victims and families impacted by decades‑old homicides, the Boston Police Department has launched a comprehensive Unsolved Homicide website spotlighting cases dating back to 1963. The initiative represents an innovative, community‑centered strategy to generate new investigative leads and breathe new life into cases that have long remained unresolved. By making case information publicly accessible, the platform leverages transparency and technology to expand the investigative reach beyond traditional methods. The site features concise case summaries, victim photographs when available, and clear, direct pathways for the public to submit tips—empowering community members to play an active role in the pursuit of justice. Several of the cases highlighted on the website are being actively worked with support from the Bureau of Justice Assistance’s Prosecuting Cold Cases Using DNA (COLD) Program, which provides critical resources to help agencies revisit cold cases using modern forensic tools and investigative strategies. By pairing public engagement with DNA‑driven cold case initiatives, the department is strengthening its ability to uncover new evidence and advance stalled investigations. This forward‑looking approach demonstrates how law enforcement agencies can maximize the impact of federal funding by combining technology, transparency, and community trust. Through this initiative, the Boston Police Department is not only revitalizing cold case investigations but also reaffirming its long‑term commitment to accountability, innovation, and bringing long‑awaited resolution to victims’ families and the broader community.
