A routine traffic stop in Vincennes turned into a major drug bust resulting in two arrests.  Indiana State Police stopped a vehicle near 9th street and College Avenue, and upon search, they say they discovered 60 grams of marijuana, digital scales, and almost $700 in cash.  They arrested Cole Walls, an 18-year-old from Terre Haute, and Trevor Humes, 21 from Anderson.  The driver was not arrested, but both Walls and Humes are being held at Knox County Jail on marijuana related charges.
