MBTA Chairman Barry Locke is caught with an envelope stuffed with cash.

Locke is caught in his office with an envelope containing $1,000 in cash. Law enforcement officials had been tipped off the day before by Locke’s assistant, James O’Leary, who had found the envelope – addressed to him but intended for Locke – on his desk. Locke is later tried, convicted, and sentenced to 6 to 10 years in prison. He is the first Massachusetts cabinet secretary to be convicted of a felony while in office.
