Tuolumne County Sheriff's Office Vehicle Jamestown, CA – Once again, a routine traffic in Jamestown resulted in an arrest after brass knuckles, an altered bb gun and meth were found during a search. Observing a car with an obstructed rear license plate at the intersection of Jamestown and Golf Links roads around 2 a.m. Thursday, a Tuolumne Sheriff’s Deputy pulled the vehicle over. When the deputy approached the vehicle, a set of metal knuckles could be seen on the lap of passenger, 28-year-old Dylan McDonald of Oakdale. Sheriff’s spokesperson Nicco Sandelin says further questioning resulted in McDonald admitting to having a pistol BB gun under his seat. Once retrieved, it appeared to have been altered to look like a real gun, according to Sandelin.
