The longtime housekeeper at a Judy Point home has been charged with stealing jewelry valued at nearly $385,000 from the residence.

Martha Lopez, 57 of Norwalk was arrested Tuesday on an outstanding warrant and charged with first-degree larceny. She had been the housekeeper for the theft victim for the last 18 years, police said.

The theft of jewelry, primarily from two safes in the Judy Point home, was reported to police last May 25, and investigated by police detectives assisted by an investigator from AIG insurance.

According to the report, 35 pieces of jewelry were stolen from the residence over the last year, with a total value of $384,330. During the investigation, police said they learned the codes to the safes were stolen from the homeowner’s day planner. The detective contacted Connecticut Gold and Silver of Wilton and learned that at least 20 items of jewelry had been pawned by the suspected thief — later identified as Lopez — between July 2012 and last December.

Photographs of the pawned jewelry were provided by Connecticut Gold and Silver of Wilton, and the victim identified 31 items as having been stolen from the residence.

Bond was set at $150,000 and Lopez is scheduled to appear Oct. 5 at state Superior Court in Norwalk.
