The death of Manuel Noriega has prompted all kinds of stories about his reign and overthrow, and the New York Times notes that it was the fatal shooting of a US military officer that proved to be the tipping point in his downfall. In December 1989, Panamanian troops killed an unarmed Marine lieutenant, wounded another US serviceman, and beat a third one while threatening to sexually assault his wife. "That was enough," said the elder George Bush in deciding to send in his US troops. An article from the time in the Washington Post explains that the servicemen were off duty and came under fire when their driver, unfamiliar with Panama City, drove close to Noriega's headquarters. The serviceman killed was 25-year-old Marine 1st. Lt. Robert Paz. Other Noriega coverage:
