A former bank manager has pleaded guilty to systematically stealing over $1.4 million from two customers in suburban New York, including a 92-year-old ex-policeman.

District Attorney Janet DiFiore says Maria Rodriguez of Mount Kisco pleaded guilty Monday to grand larceny and tax fraud.

Rodriguez was a branch manager for M&T Bank in Ossining. Several of her subordinates called the bank's whistleblower hotline. The bank contacted authorities.

The DA says the thefts began in June 2008.

The 92-year-old victim is a former Ossining Village police officer. He thought he was withdrawing only the interest out of his bank account. But the defendant was making unauthorized withdrawals.

Rodriguez faces up to 25 years in prison when she's sentenced on May 20.
