BROOKLYN - Avonte Oquendo's older brother has written an essay thanking the people of New York City for supporting his family as they searched for him.

Avonte Oquendo, who was autistic, went missing from his Long Island City school back in October. Following a massive citywide search effort, his remains were discovered in the East River in January.

Danny Oquendo says he was moved by the thousands of people who helped search for his brother and spread the word through social media. "The community came together for a common cause in such an unparalleled way, that it renewed my faith in the kindness of humanity," he says.

Oquendo is also calling for security changes to be made in schools to help protect students, including additional funding to train staff on what to do if a student goes missing. Sen. Chuck Schumer (D-NY) has already proposed Avonte's Law, which would provide electronic tracking devices to be worn by autistic students while in school.
