(DEPERE)–A 19-year-old Greenleaf, Wisconsin man will spend five years in prison for causing a Brown County crash that killed two people. Devon Robley pleaded no contest in October, to felony counts of Homicide by Negligent Operation of a Vehicle and Operating a Vehicle with a Detectable Amount of a Restricted Controlled Substance in the Blood. Two other counts were dismissed but read into the record. Prosecutors say Robley admitted to smoking marijuana at a Ledgeview park prior to the July 11, 2016 crash, saying he may have been driving at speeds around 70 miles per hour. Robley reportedly “blew” a stop sign, crashing his pickup truck into an SUV. That accident killed his passenger, 16-year-old Simon Hill of Greenleaf, and a passenger in the SUV, 32-year-old Laurie Shaha of De Pere.
