Brooklyn Supreme Court Justice Danny Chun sentenced Erin Merdy, 34, to 20 years to life for killing her three children in the Atlantic Ocean off Coney Island on Sept. 12, 2022.
Merdy had pleaded guilty in March to three counts of first-degree murder in the deaths of Oliver, 3 months, Liliana, 4, and Zachary, 7.
Prosecutors said she drowned the children near W. 35th Street after 12:30 a.m., then walked about 2 miles toward Brighton Beach, where relatives found her alone, wet and distressed before the children were discovered.
Court records said she later described nightmares about the children in the water and told police she had argued with Oliver's father over custody before going to the boardwalk to hurt herself.
The case also drew scrutiny of child-welfare oversight: authorities said Merdy had documented mental health problems, including postpartum depression, and a source previously said city child-services workers discharged her case without a psychiatric exam.
A city agency knew she was a risk. Who is truly accountable for the deaths of her three children?
Is a life sentence justice, or society’s final failure for a mother with postpartum psychosis?
