Court documents allege that Jessica Ann Lombrana, 28, of Huntertown altered receipts and deleted files from inventory records to cover thefts from Will Jewelers, where she worked since last June.
Authorities said Fort Wayne police detectives were able to match her time cards to corresponding visits to a local pawnshop, where they estimated she sold nearly $200,000 worth of jewelry.
On Wednesday, Lombrana was arrested on a preliminary charge of theft of property valued at more than $100,000.
She was also charged with receiving stolen property of an amount greater than $100,000.
In late January, the owner of the jewelry store contacted police, saying she suspected Lombrana of stealing jewelry.
An initial check of an online pawnshop database showed that she had pawned two bracelets matching items taken from the store, according to court documents.
When detectives went back to June, when Lombrana first began working at the store, they found more than two dozen times she made a trip to the pawnshop.
In some instances, Lombrana would leave the store, go to the pawnshop and then go back to work, according to court documents.
With $146,800 in losses identified, owners of the store said they discovered an additional $40,000 of inventory missing, according to court documents.
She was held in lieu of $10,000 bail, according to court records.
