Three more murders linked to Gunwalker

(GunAuction.com) -- Weapons linked to ATF's controversial "Fast and Furious" operation have been tied to at least eight violent crimes in Mexico including three murders, four kidnappings and an attempted homicide, CBS News reports.

According to a letter from U.S. Assistant Attorney General Ronald Weich to Rep. Darrell Issa (R-CA) and Sen. Charles Grassley (R-Iowa), the disclosed incidents may be only a partial list of violent crimes linked to Fast and Furious weapons because "ATF has not conducted a comprehensive independent investigation."

When added to the guns found at the murder scene of Border Patrol Agent Brian Terry in the U.S., the newly-revealed murders in Mexico bring the total number of deaths linked to Fast and Furious to four.
