AUBURN, MASS. >> A certified nursing assistant at an Auburn senior living facility has been charged with stealing a 96-year-old resident's pain medications.

Police say 46-year-old Amanda Peloquin, of Oxford, is scheduled to be arraigned Monday on two counts each of larceny of drugs and larceny from a building.

Peloquin was arrested Friday following an investigation sparked by the woman's son, who said some of his mother's medications were missing. Police say the medications had been replaced by a similar looking pill that turned out to be aspirin.

Police think Peloquin was stealing drugs for two years. She had worked at Brookdale Eddy Pond East senior living facility for six years.

It was no clear if Peloquin had a lawyer.
