Jonathon Minard, Ohio teenager, missing after helping a friend on the family farm

Authorities in Ohio are looking for a teenager who has disappeared this weekend after helping a family farm, investigators said.

14-year-old Jonathon Minard spent Friday afternoon doing "housework" on a farm near New Harrisburg before leaving that night with a 29-year-old friend whose family owns the farm. Carroll County Sheriff Dale Williams told NBC News.

Minard, who lives with his parents in Dellroy, Ohio, spent the night at his friend's house before returning home on Saturday to work more, Williams said.

In the afternoon, Minard began to complain about toothache and tried to contact his mother so he could return home, Williams said. The authorities have been looking for the teenager ever since.

"Our inspectors are working diligently and are following all the reported incidents," said the sheriff's department on Facebook, claiming that Minard had been seen for the last time wearing a blue hoodie, trousers brown and brown boots.

Williams said that there was a person of interest in the case but refused to disclose a name. Wednesday morning, Minard is still missing.

Jo Hepner, the aunt of the teenager, pleaded in tears for anyone with information about Minard to show up.

"If you really know where it is and what has happened to it, tell us," she told NBC affiliate WKYC. "I mean, we beg you, I mean, it's our last hope."

Authorities have asked residents to check their garages and properties for any suspicious items.
