Police in Port Clinton, Ohio, said Harley Dilly, 14, died after he climbed into the house's chimney on his own and became trapped in a space of about 9 inches by 13 inches, Chief Robert Hickman said.
The state Bureau of Criminal Investigation, part of the Ohio Attorney General's Office, issued an advisory at 7:58 a.m. on Tuesday to end the hunt for Dilly, who vanished on his way to school on December 20 in Port Clinton, about 80 miles west of downtown Cleveland. His maroon puffy coat and glasses, which he was wearing when he was last seen, were found on the floor near the chimney's flue in a fireplace on the second floor.
Police searched for Dilly for weeks, but with no success, Cleveland's Fox 8 reported.
Hickman tried not to break down in tears during a press conference on Tuesday where he announced that Dilly was dead.
Police are saying Harley Dilly's death was accidental and foul play does not appear to be a factor. Once inside, Dilly's coat and glasses were found.
The Ohio Attorney General's office canceled an Amber Alert Tuesday, stating the "child has been recovered".
No cause of death has been determined.
Authorities first thought the teen may have run away from home, because he sometimes spends a night away from home if he gets upset.
Since then, volunteers and authorities searched through nearby neighborhoods along Lake Erie with help from K-9 teams and helicopters.
An autopsy will be performed on Tuesday, but there is no evidence of foul play, according to Hickman.
¯ The owners of the house did not visit it at any time while Dilly was missing. "Since there is a lockbox and anyone can go in and out of the house, we went inside to check the house", said Hickman.
Officers who responded to the home had to calm the boy down but gave no additional information about the incident.
Authorities said 14-year-old Harley Dilly's death is now being considered an accident and they have found no signs of foul play.
