VIENNA — A man who reported his son missing Sunday now faces marijuana possession and cultivation and endangering the welfare of a child charges, according to Kennebec County Sheriff Randall Liberty.

Jonathan Lehr, 41, reported his 3-year-old son missing Sunday afternoon. The son, Ben, was found after about a 4 1/2-hour search when a Maine Warden Service pilot spotted the tot in a field of golden rod about 700 yards from the home.

The boy was shirtless, dehydrated and disorientated when found but was treated and released by rescue workers on the scene, according to Liberty.

During the search deputies also discovered 147 marijuana plants and 1/4 pound of processed marijuana at the Lehrs’ home, Liberty said in a news release.

The elder Lehr now faces charges of marijuana cultivation, criminal possession of marijuana and endangering the welfare of a child. The Maine Department of Health and Human Services is investigating the complaint, Liberty said.
