A Jersey City man is expected to spend a year-and-a-half in state prison after pleading guilty to sexually abusing an underage employee he supervised. Rockland D.A. Tom Walsh says 37 year-old Jonathan Valencia admitted to one count of rape in the third degree stemming from an incident two years ago at a Jersey Mike’s Sub store. The case was investigated by the Clarkstown Police and the D.A.’s Special Victims Unit. Valencia is scheduled for sentencing in February. Valencia and a partner opened Jersey Mike’s in Nanuet in February 2018.
