Lindsay Marie Clancy

OVERVIEW & LEGAL HISTORY SUMMARY

Lindsay Marie Clancy (born August 11, 1990) is a former labor and delivery nurse at Massachusetts General Hospital and resident of Duxbury, Massachusetts. She is the defendant in a capital murder prosecution involving the January 24, 2023, strangulation deaths of her three young children: Cora (age 5), Dawson (age 3), and Callan (age 8 months). Following the birth of her third child in May 2022, Clancy experienced severe, escalating psychiatric deterioration characterized by profound insomnia, anxiety, intrusive thoughts, and depersonalization. Between September 2022 and January 2023, she repeatedly sought medical intervention, undergoing multiple emergency room visits, a day treatment program, and a voluntary stay at McLean Hospital. During this four-month period, outpatient clinicians prescribed a rapidly shifting combination of 13 psychotropic medications across 32 filled prescriptions. On the evening of January 24, 2023, while experiencing command auditory hallucinations, Clancy strangled her three children in the basement of her home, slashed her neck and wrists, and jumped from a second-story window, sustaining spinal cord trauma that left her permanently paralyzed from the waist down. Authorities obtained an arrest warrant on January 25, 2023, while Clancy was hospitalized. She was arraigned via Zoom from her hospital bed and subsequently transferred under state custody to Tewksbury Hospital. On September 15, 2023, a Plymouth County grand jury formally indicted her on three counts of first-degree murder. Defense counsel Kevin Reddington pursued an insanity defense under the Massachusetts McHoul standard, asserting that severe postpartum psychosis, bipolar disorder, and drug-induced akathisia deprived Clancy of substantial capacity to appreciate the wrongfulness of her conduct or conform her actions to the law. Trial commenced in Plymouth Superior Court on July 20, 2026, before Judge William F. Sullivan. Over seven weeks, the jury heard testimony from 70 witnesses, including forensic psychiatrists, treating physicians, and police investigators. On September 4, 2026, following seven days of deliberation, Judge Sullivan declared a mistrial due to an irreconcilable 11-1 jury deadlock, with 11 jurors favoring a verdict of Not Guilty by Reason of Insanity (NGRI). Following the mistrial, Clancy's defense team filed a renewed motion for a required finding of not guilty under Mass. R. Crim. P. 25(b)(2), asserting that prosecution evidence was legally insufficient to establish sanity beyond a reasonable doubt. Status hearings were set for late 2026 to address retrial scheduling and outstanding defense motions. Concurrently, Clancy remains the lead plaintiff in a civil medical malpractice lawsuit filed in Norfolk Superior Court against 11 healthcare providers alleging negligent psychiatric care and improper medication management.
