ROLLINGSTONE, Minn. — U.S. Postal detectives staged a sting and claimed to have caught a Rollingstone mail worker red-handed opening a package and stealing prescription pills. Miranda Diane Tesch of St. Charles faces two counts of felony theft of mail. The sting was in November, although she was charged only Thursday through a summons. Here’s what happened: Alerted to theft reports over several months, agents put together a package made to resemble a prescription delivery from a VA hospital. Inside they put a bottle with fake pills and a sensor designed to trigger upon opening. An undercover agent took the package to the Rollingstone post office, where Tesch was working alone. The agent told her that a relative had died. The agent requested the package be returned to  the VA hospital. The agent left and waited outside with a fellow agent. The sensor in the decoy package went off. They rushed in. They read Tesch a Garrity warning that advised her she was compelled as a federal employee to answer their questions. At first, they said, Tesch claimed she opened the package to find identifying information because she could not make out what was the label. Eventually, they said, she admitted to opening the pill bottle. Agents found the 28 fake pills in her own prescription bottle, which was in her purse.
