A former worker of the California State Controller's Workplace pleaded guilty to 3 felony counts of grand theft in connection with the theft of diamonds and coins across a number of years, according to the Sacramento County District Lawyer's office.

The Controller's Office handles the state's money, audits federal government agencies that use state funds, and safeguards unclaimed residential or commercial property.

The DA stated that the California Highway Patrol began an investigation when $300,000 worth of diamonds went missing out on from a mailroom at the Controller's Office in Sacramento.

Video monitoring video footage showed the staff member take a package of diamonds to a room that had no video cameras and after that go back to the mail space, the DA said.

The employee then re-taped the bundle and returned it to the mail for shipment.

When the CHP served a search warrant at the worker's home in Sacramento, officers found the diamonds, together with other coins and jewelry.

The CHP and the Controller's Office were able to trace the coins and fashion jewelry to ten other victims, with the jewelry having actually been taken over 7 years, the DA stated.

The former worker, who operated in the mailroom of the Controller's Office for more than a decade, will be sentenced to 3 years and 4 months in early April, the DA said.
