Terry's death sparked outrage when it was revealed the guns used in the shooting were supplied by the United States government.
The incident exposed the "Fast and Furious" operation, in which federal agents allowed criminals to buy weapons. The plan was to track the firearms into Mexico, but instead, the agents lost track of most of them.
Two of those weapons were found at the site of the gun battle that left Terry dead.
Fox News said U.S. and Mexican authorities found Osorio-Arellanes at a ranch near the border of Sinaloa and Chihuahua.
Authorities said a five-man rip-off crew was attempting to rob marijuana smugglers in the Arizona desert in December 2010.
The group encountered federal agents patrolling the area and Terry was killed in the ensuing gun battle.
Six men in total have been arrested in connection with the shooting and authorities are still looking for Jesus Rosario Favela-Astorga, who's wanted on murder, conspiracy, robbery, assault and firearm charges.
Along with Osorio-Arellanes and Favela-Astorga, the other three men present when Terry was killed are Ivan Soto-Barraza, Jesus Sanchez-Meza and Manuel Osorio-Arellanes. Soto-Barraza, Sanchez-Meza received life sentences for their roles while Osorio-Arellanes was sentenced to 30 years.
The other two men involved are Jaime Avila Jr. and Rosario Rafael Burboa-Alvarez. Authorities said Avila was responsible for buying the weapons and Burboa-Alvarez organized the rip-off crew. Both were not present when Terry was killed but Avila is serving a 57-month sentenced while Burboa-Alvarez was sentenced to 27 years.
