Fifty seven previously unidentified firearms linked to Operation Fast and Furious were recovered in sites associated with murders, kidnappings, and at least two gruesome massacres.
Univision News obtained the list of Fast and Furious weapons and a list containing almost 60,000 recovered firearms compiled by Mexico's Secretaría de la Defensa Nacional (SEDENA). A cross-reference of the serial numbers of the guns resulted in 96 full matches (several partial matches were discarded).
