The mother of 2-year-old Montrell Williams, who was found dead earlier this year in the water at Ferry Point Park, is taking the city and the NYPD to court over the death of her child.

The claim comes from what is described as the "wrongful death, negligence, and negligent failure to act" from New York City and its agencies, namely the NYPD, for its response to repeated reports of Montrell Williams being missing weeks before he was found dead.

Funeral service remembers 2-year-old Montrell Williams as father faces murder charges

His father, Arius Williams, has been charged with murder in the death of the child. He was arrested after failing to return his son to the boy's mother after a scheduled visitation on May 11.

The claim states that Montrell was in the care of his father on May 10 and that Arius Williams failed to return Montrell to his mother, Cierra Carroll. Carroll filed a missing report the following day, and the NYPD officers allegedly classified the call as a custody dispute, failing to start the missing child investigation or an Ambert Alert.

The document states that Carroll and her mother repeatedly urged the NYPD to take action until May 28, when a family court arrest warrant was issued for Arius Williams. Montrell's body was recovered in the East River near Ferry Point park on June 11.

This lawsuit claims that the city and NYPD failed to take "timely and reasonable action" to locate and protect the child, despite knowledge of the father's history of domestic violence, involvement of police in domestic disputes, the father's public social media statements of guilt, and the immediate danger to the child's life.
