A Brooklyn mother has been sentenced to 20 years to life in prison for causing the drownings of her three young children in the ocean near Coney Island’s famous boardwalk in a case that has shocked local residents and drawn wide attention. The sentence was handed down Wednesday in Brooklyn Supreme Court, after the woman — 34‑year‑old Erin Merdy — entered a guilty plea to three counts of first‑degree murder earlier this year.
Tragic Incident in 2022
The deaths occurred in the early hours of September 12, 2022, when Merdy took her three children — 7‑year‑old Zachary Merdy, 4‑year‑old Liliana Stephens, and 3‑month‑old Oliver Bondarev — to the shoreline near West 35th Street in Coney Island. According to prosecutors, she drowned each child in the Atlantic Ocean before leaving the scene and walking toward an apartment in Brighton Beach.
Family members became alarmed when Merdy expressed distress and concern about the children’s well‑being, and they contacted police after she became unreachable. Officers later located the children unresponsive on the beach and they were pronounced deceased at Coney Island Hospital.
Court Proceedings and Sentence
Merdy was arrested and later charged with multiple counts of murder. In March 2026, she pleaded guilty to first‑degree murder in connection with the deaths of her children. At Wednesday’s hearing, Brooklyn Supreme Court Justice Danny Chun sentenced her to 20 years to life in prison, the minimum term before parole eligibility under New York law.
Brooklyn District Attorney Eric Gonzalez said in a statement that “no sentence can fully measure the loss of a seven‑year‑old, a four‑year‑old and a three‑month‑old baby — or the grief their loved ones will carry forever.” Gonzalez added that the sentence ensures Merdy will be held responsible for taking the children’s lives.
Evidence and Investigative Details
Evidence against Merdy included video footage showing her walking toward the ocean with the children before 1 a.m. on the night of the incident. Prosecutors also noted that family members alerted authorities based on concerns about her behavior and mental state that night.
When found by relatives on Brighton Beach, Merdy was described as wet and barefoot, and told them the children were gone, according to legal filings and statements.
Medical examiners ruled the children’s deaths homicides by drowning.
Community Reaction
The heartbreaking nature of the case has resonated with local residents and advocacy groups, prompting renewed discussion around mental health support and resources for families in crisis. While some reports suggested Merdy may have faced challenges such as postpartum depression prior to the incident, officials emphasized that the legal process focused on accountability and the loss suffered by the children’s family.
