LINCOLN, Neb. (AP) — The mother of a former Nebraska prison guard has been accused of throwing away evidence against her son.

Court records say 41-year-old Jacinda Miller, of Oshkosh, is charged with felony evidence tampering. She didn’t immediately return a call Monday from The Associated Press. Court records don’t list the name of an attorney who could comment for her.

The records say her son, 25-year-old Michael Miller, is accused of trying to smuggle synthetic marijuana and other contraband into the Nebraska State Penitentiary in Lincoln, where he worked until resigning in November.

A court document says he told investigators he’d asked his mother to go to his Lincoln apartment and get rid of the drugs. He says she told him after she bonded him out of jail that she’d disposed of them.
