MA v Lindsay Clancy - Dr. Renee Stonebridge - Forensic Pathologist

Testimony of Dr. Renee Stonebridge, a forensic pathologist, regarding her autopsies of the Clancy children: Background and Professional Qualifications • Employment: Dr. Renee Stonebridge has been employed with the Commonwealth of Massachusetts Office of the Chief Medical Examiner (OCME) in Boston since July 2017. • Current Role: She serves as the Director of Cardiac and Neuropathology and is also a medical examiner, focusing primarily on the examination of brains and hearts. • Board Certifications: Board-certified in forensic pathology, anatomic pathology, clinical pathology, and neuropathology (the study of the brain, dura, eyes, spinal cord, and muscle). Education: • Undergraduate: Double major in German languages and literature and biology from SUNY at Stony Brook. • Medical Degree: Graduated magna cum laude with honors from the American University of Antigua. Post-Graduate Training & Certifications: • Completed a four-year combined anatomic and clinical pathology residency at NYU Winthrop Hospital, serving as chief resident from 2016 to 2017. • Completed a one-year forensic pathology fellowship at the Boston OCME. • Completed a two-year neuropathology fellowship through Brown University at Rhode Island Hospital. Protocol for Neuropathology Consultations • Referral Criteria: Other medical examiners refer specialized tissues (like brains or eyes) to her based on specific criteria: • Any deceased child under the age of two. • Cases with suspicion of homicidal head injury (typically blunt trauma). • unexpected findings discovered during an autopsy (e.g., tumors or rare neurodegenerative diseases) that require specialized neuropathological evaluation. Autopsy Findings: Cora Clancy • Tissues Examined: Eyes. • Pathological Findings: • Acute hemorrhage of the extraocular muscles and surrounding adipose (fat) tissue. • Punctate hemorrhage in the left optic nerve sheath. • Forensic Conclusion: These findings are consistent with an asphyxial mechanism (such as neck compression or strangulation). Autopsy Findings: Dawson Clancy • Tissues Examined: Eyes. • Pathological Findings: • Acute hemorrhages in the extraocular muscles and adipose tissue surrounding the eyes. • Small hemorrhages in the posterior retina and the connection point of the right optic nerve sheath. Autopsy Findings: Callan Clancy • Tissues Examined: Brain, dura, spinal cord, and eyes. • Pathological Findings: • Hypoxic ischemic changes: Brain injury resulting from a lack of appropriate blood and oxygen flow, which ultimately led to brain death. • Brain Edema: Severe swelling that caused the brain to press against the skull, flattening its natural bumpy surface pattern. • Ventricle Compression: Swelling of the brain tissue squashed the internal ventricles (the tunnel system carrying cerebrospinal fluid). • Diffusely Friable Tissue: The brain was extremely soft and failed to firm up properly even after being placed in a formalin fixative for the standard two weeks, because the tissue was already dead when received. Underlying Medical and Forensic Concepts • Mechanics of Eye Hemorrhage: During neck compression or other asphyxial events, blood is trapped in the head and cannot flow back down to the body. This buildup of pressure blocks and bursts the tiny blood vessels in the eyes, skin, and mouth, creating localized hemorrhages. • Timeframe for Brain Death: Brain tissue begins to die within approximately six to eight minutes of a complete loss of blood and oxygen flow. Once brain tissue dies, it is irreversible and cannot be brought back. 00:00 - MA v Lindsay Clancy - Dr. Renee Stonebridge 02:10 - Protocol for Neuropathology Consultations 03:16 - Autopsy Findings: Cora Clancy 04:53 - Forensic Mechanics of Asphyxial Eye Hemorrhages 06:13 - Autopsy Findings: Dawson Clancy 07:02 - Autopsy Findings: Callan Clancy 09:56 - Timeframe and Mechanics of Brain Death Lindsay Clancy Trial Playlist:    • MA v Lindsay Clancy
