New York ( CNN ) A missing eighth-grade student who was found dead near his Pennsylvania home on Sunday died from a self-inflicted gunshot wound , according to the county medical examiner . Cayman Naib , 13 , vanished Wednesday after leaving his home in Newtown Township without his wallet or his phone , according to his parents . A K-9 unit located his body Sunday afternoon some 150 yards away from his home , said Mark Hopkins , chief of Greater Philadelphia Search and Rescue . Hopkins said Naib was under snow , and in a `` sleeping position . '' Brian Razzi , chief of administration at the Delaware County Medical Examiner 's Office , determined Monday that it was a suicide . Naib 's parents confirmed the news on Facebook . `` For those who have been following the Naib family 's sad and incredibly devastating news , we have just learned from the medical examiner 's office that Cayman took his own life , '' wrote Becky and Farid Naib . `` The cause of death was a self-inflicted gunshot wound to his head . '' They said the gun had been taken from the home . `` The police have informed us that despite being fitted with a trigger lock , the gun was still able to be fired , '' they said Monday . The Naibs said Cayman 's suicide most likely occurred Wednesday evening , just hours after he walked out of his home upon receiving an upsetting email from his school . `` Cayman left within 30 minutes after he received an email from school regarding overdue homework ( we do not blame the school ) and most probably did not do any preplanning , '' read a Thursday facebook post . `` He is a good kid , and has no substance abuse or other issues , this is the first time he has ever done anything like this , '' the parents wrote . A search for the teen had drawn hundreds of volunteers , who traded messages and posted updates on a Facebook page called `` Find Cayman . '' `` The family would like to reiterate their profound gratitude and appreciation for all the thousands of friends , family , community , law enforcement , local , county , and federal , search and rescue , fire departments , the school communities ... and even perfect strangers who came out to volunteer , supported them with prayers and good wishes , and have loved them through this heartbreaking ordeal , '' read a Monday post on the site , since renamed `` Celebrating Cayman . '' `` Their only solace throughout these past few days has been the closure they have received from the community 's efforts to find Cayman . '' CNN 's Kristina Sgueglia , Dana Ford and Renee Wunderlich contributed to this report .
