Often lost amid the rancor in Washington are the stories of dozens of people killed by guns that flowed south as part of the undercover operation, and later slipped out of view from U.S. officials. Univision's Investigative Unit (Univision Investiga) has identified massacres committed using guns from the ATF operation, including the killing of 16 young people attending a party in a residential area of Ciudad Juárez in January of 2010.
Additional guns, previously unreported by congressional investigators, found their way into the hands of drug traffickers across Latin America in countries such as, Honduras and Colombia, as well as the U.S. Commonwealth of Puerto Rico. A person familiar with the recent congressional hearings called Univision's findings "the holy grail" that Congress had been searching for.
