NEW YORK - (AP) - Human remains found last week along the East River belong to an autistic teen who walked out of his school more than three months ago and vanished, the medical examiner's office said Tuesday.
Avonte Oquendo's remains, a left arm and lower torso and legs, were identified through DNA given by his family. They were discovered Jan. 16 after a teenager shooting photos for a school project noticed the arm. Pieces of Avonte's clothing were also recovered. A part of a skull was recovered a few days later.
The cause and manner of death were pending further study, the medical examiner said.
It was a sad end to a case that sparked a massive citywide search that included hundreds of officers, marine units and volunteers. Missing person posters were plastered on lampposts and placed on car windshields throughout the city.
The teen, who did not speak, was fascinated with the subway system and Metropolitan Transportation Authority officials made announcements on trains for weeks asking for help finding him. Police checked every subway station and tunnel.
Authorities also hunted down hundreds of tips in New York City and its suburbs.
Avonte had been missing since Oct. 4, when he walked out of his school toward a park overlooking the river.
Avonte's family has filed a notice of claim saying they planned to sue the city, arguing that school officials allowed him to walk out of the building and waited too long to notify police that he was missing. City authorities had defended the school safety officer who last saw the boy, saying she told him to go back to his classroom and he left the hallway. The city's law department has said the case is "distressing."
Avonte's mother, Vanessa Fontaine, and other relatives had been holding out hope that the boy was still alive. Her lawyer, David Perecman, said last week that she was waiting for the DNA test results.
"Her initial reaction was, 'until I hear more or see more'... She's not going to be convinced it's her son unless there's enough to convince her," said Perecman.
Perecman was planning to hold a news conference later Tuesday.
