A Brooklyn mother has been sentenced to 20 years to life in prison for the drowning deaths of her three young children off Coney Island. Erin Merdy, 34, learned her fate on Wednesday after pleading guilty to first-degree murder charges earlier this year in the 2022 killings of her children: seven-year-old Zachary, four-year-old Liliana, and three-month-old Oliver, according to Brooklyn District Attorney Eric Gonzalez.
The Tragic Night
On September 12, 2022, Merdy took her children to New York's Brighton Beach around 12:30 a.m. and drowned them in the ocean. About an hour later, she began walking from the beach toward an apartment belonging to Oliver's father, calling family members in a distraught state but unclear about the children's whereabouts. The father then called 911, prompting police to search for the children. Around 4:30 a.m., they were found unresponsive and soaking wet. All three were pronounced dead at the hospital, and a medical examiner later ruled their deaths homicides by drowning.
Mother's Condition and Lawsuit
After news of the tragedy broke, Merdy's family stated she was battling severe postpartum depression when she took her children's lives. Derek Merdy, her ex-husband and Zachary's father, along with Shamir Small, Liliana's father, filed a lawsuit in the Supreme Court of New York against the City of New York, the Administration for Children's Services (ACS), and others. The suit alleges that agencies failed the children, citing Merdy's history of mental health issues and ACS involvement. The lawsuit claims Merdy was an unstable mother with severe mental health problems, physically abusive to the children, neglected them by withholding food, and disappeared leaving them unsupervised. It documents multiple instances where she violated custody agreements and displayed erratic behavior. Two reports were filed with ACS, but investigations were closed despite knowledge that Merdy was not receiving mental health treatment.
DA's Statement and Father's Tribute
Following sentencing, DA Gonzalez stated, 'Zachary, Liliana and Oliver were innocent children whose lives were taken in the most heartbreaking and unthinkable way. No sentence can fully measure the loss... We sought the strongest possible accountability.' Shamir Small, Liliana's father, laid her to rest in a Queens funeral, saying Merdy loved their daughter. 'Contrary to what happened, she was loved by her mother. What she did was monstrous, but she herself is not a monster,' he said. He asked that his daughter be remembered for how she lived, not how she died. Liliana was dressed in a pink dress in a white casket, with a Barbie doll placed inside.
Background and Community Reaction
Police had responded to six domestic incidents involving Merdy, including one on July 2, 2022, where she refused to hand over children to her husband. Court records show she faced eviction due to thousands of dollars in unpaid rent. Joseph, a maintenance worker in her building, expressed shock: 'To go and drown your children - I wonder what was on her mind... It's just a sad situation.'
