PORT CLINTON, Ohio (WJW) -- Port Clinton police said they don't have many leads in their search for missing 14-year-old Harley Dilly.
"We are searching as if Harley is still alive," Chief Robert Hickman said in a press conference Thursday.
There is now a $4,000 reward for information leading to Harley's safe return.
Harley was last seen on his way to school December 20 between 6 and 7 a.m.
He was wearing glasses, grey sweatpants, a maroon puffy jacket and black tennis shoes.
According to a police report, Harley's father filed a police report at the department on December 21 just before midnight.
Port Clinton police, Ohio's Bureau of Criminal Investigation and several other agencies are combing 150 acres for any sign of Harley.
Police say they've interviewed friends. No one has seen or heard from Harley, according to their interviews.
Police say they were called to the family home about one month ago to "calm" Harley down after a disagreement with his parents.
"Harley will not warm up to anybody who will approach him all I can ask if the public sees Harley call whatever agency call 911," said Chief Hickman.
The family home was searched for any clues about Harley's whereabouts and his parents are cooperating in the investigation. Nothing suspicious was found.
Police say they spent Christmas Eve and Christmas Day reviewing more than 40 hours of video footage in order to locate Harley's last known location.
