–
On March 20, 2014, in the Western District
of Texas, Oliver Bres-Carranza was sentenced to 51 months in federal prison after pleading
guilty in October 2013 for his role in a scheme to smuggle defense articles into the Republic of
Mexico. On January 15, 2014, Erik Alan Garza was sentenced to 44 months in federal prison and
fined $3,000 for his role in the smuggling scheme. Garza, Bres-Carranza and Rolando Tamayo
were charged in a June 2012 indictment with multiple counts of aiding and abetting the
smuggling of goods from the United States. According to the indictment, between June 19, 2010
and February 17, 2012, Garza and his accomplice, Tamayo, illegally attempted to smuggle defense articles into the Republic of Mexico from the United States.
Those items included night vision monocular goggles, a thermal goggle, 400 sets of AR-15 front and rear flip-up tactical sights,
approximately 5,000 high-capacity assault rifle magazines and approximately 6,000 rounds of ammunition, including 100 rounds of .50 caliber ammunition.
Tamayo remains a fugitive.
This case was investigated by ICE and ATF
