The Douglas County Sheriff’s Office arrested three Reno teenagers early Thursday in Minden after finding about 8 pounds of marijuana, more than 1.25 pounds of concentrated THC, almost $2,000 in cash and a Glock 19. Joseph Anthony Coleman and Erin Sadzak, both 19, were arrested as well as a 17-year-old the sheriff’s office did not identify. Charges among the defendants included drug trafficking and firearms charges. Deputies were patrolling on US 395 in Minden at about 2:30 a.m. when they stopped a vehicle with the three defendants for speeding. Deputies smelled marijuana from the vehicle and did a field narcotics investigation that found the drugs.
