Medical Examiner: Cause Of Avonte Oquendo's Death Impossible To Determine

NEW YORK (CBSNewYork/AP) -- The cause of Avonte Oquendo's death cannot be determined, the New York City's medical examiner's office says.

The 14-year-old autistic boy disappeared from his Queens school on Oct. 4, setting off a massive search that included subway tunnels and regular announcements over the PA system at subway stations.

His remains were found on the shore in College Point, Queens, several miles from where he vanished.

Avonte was severely autistic and unable to speak.

The boy's family has demanded an explanation from the city as to how Avonte was able to walk out of school unnoticed. They have said they plan to file a wrongful death lawsuit against the city.
