The mother of an autistic New York City teen found dead more than three months after he disappeared plans to file a wrongful death lawsuit against the city.
The announcement came after the city medical examiner confirmed that the human remains found along the East River were those of 14-year-old Avonte Oquendo.
Attorney David Perecman said he will file the legal claim on behalf of the family.
He said Avonte's mother, Vanessa Fontaine, is inconsolable.
The family first said in October that it would sue the city over claims he was not supervised properly.
Avonte vanished on October 4 after leaving the Center Boulevard School in Long Island City, Queens.
The autistic teen, who was unable to communicate through speaking, was the subject of massive search effort.
Avonte's remains were not intact when they were discovered on the banks of the East River over the span of a few days.
A teenage girl shooting photos in a Queens park noticed a left arm, leading to the discovery of legs and lower torso.
A part of a skull was also later recovered.
Authorities said at the time that clothing consistent with what Avonte was wearing when he went missing was also found.
The medical examiner said on Tuesday that the cause and manner of death are pending further study.
