A former employee of Trustmark National Bank has been charged by the U.S. Attorney’s Office in Jackson with embezzling more than $1 million from the bank’s vault over the past four years.

Astrid Warnock, age unavailable, of Utica, agreed to waive indictment and plead guilty to embezzlement. An arraignment is set for June 19 before U.S. Magistrate James C. Sumner in Jackson.

Warnock’s guilty plea will be set for a later date and will be before U.S. District Judge David Bramlette, Assistant U.S. Attorney Cynthia Eldridge said.

If found guilty, Warnock faces up to 30 years in prison or a $1 million fine.

According to the bill of information released Friday by the U.S. Attorney’s Office, Warnock took from the bank vault cash in increments of up to $10,000 at a time and created bogus debit and credit tickets to cover up the theft.

The incidences of theft occurred between Jan. 1, 2002 through March 2 of this year, said the bill filed in federal court in Jackson Thursday. During part of that time, Warnock worked as the head teller at the main Trustmark branch at Washington and Clay streets.

The end of that time frame coincides with the start of the investigation, Eldridge said, when bank officials &#8220discovered some serious issues.”

&#8220The bank reported it to the FBI immediately,” Eldridge said.

Telephone calls to Warnock and officials with Trustmark National Bank in Jackson were not returned.

&#8220It’s not something I can comment on if it’s under investigation,” said Jerry Hall, president of Trustmark’s locations for the Vicksburg and Delta region.
