A New Castle man is facing a long list of charges after he allegedly sexually assaulted a 15-year-old girl he met on a dating app. 44-year-old Douglas Gilghrist allegedly traveled to Montgomery County last summer after meeting the teen on the app. State police say he sexually assaulted and had indecent contact with the victim on a number of occasions. Gilghrist was arrested last week at his workplace. He’s now being held in the Lawrence County jail.
