BROOKLYN - The citywide search for an autistic teenager is showing no signs of slowing down more than two weeks after he went missing.

Police, volunteers and community organizations are all pitching in to help find 14-year-old Avonte Oquendo, who is unable to communicate verbally and is supposed to be watched at all times.

The Queens resident was last seen at the Center Boulevard School in Long Island City on Oct. 4 where surveillance video shows he left the school through a side door.

Authorities released a new picture of the actual shirt Oquendo had been wearing when he disappeared. The reward for his safe return has risen to $89,000.
