AUSTIN, Minn. -- Two teens accused of searching for a marijuana dealer dialed the ultimate wrong number -- they called the Mower County Sheriff's cell phone. Sheriff Terese Amazi's cell phone rang around noon on Friday. The caller said she wanted a bag of marijuana. After Amazi said she was the sheriff, the caller said, "I'm sorry," and hung up. A few minutes later, the phone rang again. This time, Amazi let a deputy answer. The caller again asked for a bag of marijuana, and the deputy -- who called himself "Dupe" on the phone -- arranged for a meeting at a convenience store an hour later. "Apparently, they didn't know the meaning of 'Dupe' as in 'duped' either," Amazi said. "It's incredible." The girls, ages 15 and 17, were arrested at the scene. Police said they found cash for the marijuana and drug paraphernalia on both girls. One was released to her parent and the other was turned over to a probation officer. "Not only did they do something wrong, but they should have been in school," Amazi said.
