A front office employee of the San Francisco Giants may be facing a lengthy jail sentence after her arrest on federal embezzlement charges.

KGO-TV in San Francisco reports Robin O'Connor worked as the teams payroll manager for four years, but is facing formal charges of wire fraud and fraud in connection with a computer. She faces a penalty of up to five years in federal prison per count.

O'Connor, 41, married with two small children is accused of embezzling $1,513,836.28 from the World Champions payroll between June of 2010 and June of this year.

The scheme broke down when O'Connor applied for a loan to buy a house in San Diego. The FBI affidavit says she forged a letter from the Giants' HR manager, explaining huge deposits had been placed into her account.

Despite an $80,000 salary, O'Connor and her husband each had 2011 model-year cars, a BMW sedan and SUV -- with a Giants' employee parking sticker -- and a loaded Ford F-150 truck.

KGO reports the Giants wouldn't say which players' accounts were embezzled.

O'Connor was released on a $500,000 bond. She has surrendered her passport and is scheduled to be arraigned in a month.

The San Francisco Examiner has further details on the story, reporting O'Connor was fired July 6.

Late Tuesday night, the Giants released a statement:

"Last month, the San Francisco Giants discovered evidence of possible embezzlement by our former payroll manager, Robin O’Connor, which resulted in her dismissal. We immediately notified the United States Attorney's office and are working with the federal authorities to ensure that this matter is thoroughly investigated and that any wrongdoing is prosecuted to the fullest extent of the law. The United States Attorney's Office has requested that we refrain from providing additional details at this time to protect the integrity of the ongoing investigation."
