Eugene Carroll was a retired U.S. admiral who met with Cuban officials in Havana the day before the Cuban Air Force shot down two Hermanos al Rescate planes flying over Cuban airspace in February 1996. During the meeting, Cuban officials made comments that strongly hinted at the possibility of an attack. Carroll forwarded this information to the U.S. Defense Intelligence Agency (DIA), but the attack proceeded the next day nonetheless. When word broke that the DIA had known about and failed to prevent the attack, the revelation portrayed the U.S. government as incompetent and ineffective. The coincidence of the timeline—Carroll receiving warning of the attack a mere day before it played out—heightened DIA analyst Reg Brown’s suspicions that a DIA colleague was operating as a Cuban spy.
