As has been the case with much of the timeline in the Bureau of Alcohol, Tobacco, Firearms and Explosives "Fast and Furious" operation, the details just seem to get worse.
This time, Univision claims it has linked 57 guns from Mexican crime scenes to the "Fast and Furious" operation -- 57 weapons that were not included in Congress' July report that 122 weapons from the "gunwalking" operation had been recovered in Mexico.
Additionally, according to Univision, some of those guns were recovered not just at crime scenes, but at the scenes of two massacres.
One of those massacres was on January 30, 2010 in Ciudad Juárez, in which cartel members started shooting at a birthday party being celebrated by about 60 teenagers. Fourteen were killed, and another 12 were injured.
The other massacre is described by Univision as an attack on a Juárez rehab center, which left 18 people dead in 2009.
Univision was able to find this out by comparing serial numbers in the "Fast and Furious" operation to serial numbers of guns found out crime scenes, provided by Mexico's national defense agency.
As of a year ago, 11 firearms were found at crime scenes in the United States that were linked to "Fast and Furious," and four of those were in Arizona -- five, if you include firearms found at the scene of slain U.S. Border Patrol Agent Brian Terry.
While guns from this operation are still unaccounted for, the blame-game is still going on within the federal government, as Attorney General Eric Holder just recently claimed the Justice Department's inspector general's report exonerated him from any wrongdoing.
