The suspects offered $1.5 million and “multi-ton” quantities of opium as payment. This case illustrates that we live in a world where borders and boundaries are increasingly irrelevant. According to the criminal complaint the Iranian suspect wanted to hire the Zetas because the cartel had access to military grade weaponry including explosives.  "I think the Zetas have the reputation of being the most ferocious and violent drug cartel in Mexico and so this Iranian agent may have thought the Zetas will do anything, that they’re cold blooded killers, and they’re capable of pulling something like this off." said Howard Campbell, author of the "Drug War Zone. The Zetas are behind some of the most brutal and brazen killings in Mexico including grenade attacks in public places, a casino fire in Monterrey that killed dozens of people and the murder of a U.S. federal agent working in San Luis Potosi. His partner was wounded. The suspect named in the criminal complaint traveled to Mexico on several occasions to work out the details of the terrorist attack.  A source says one meeting happened in Reynosa on the Texas border. In the end, he was not dealing with the violent Zetas but a drug trafficker who is paid informant for the US government.
