BROOKLYN - The NYPD Police Commissioner Ray Kelly says it's unlikely that Avonte Oquendo will be found alive.

Today marks three weeks since the 14-year-old autistic boy went missing from his Queens school.

Police, family, friends and community members have searched each New York borough. Oquendo's family says the boy is non-verbal and has a fascination with trains.

Anyone with information on the teenager's whereabouts is asked to call Crime Stoppers at 1-800-577-TIPS. An $85,000 reward is being offered for his safe return.
