Border Patrol Agent And State Prison Guard Sentenced To Lengthy Prison Terms For Bribery, Drug Trafficking, And Murder Scheme

For Immediate Release
U.S. Attorney's Office, District of Arizona

PHOENIX, Ariz. – On November 5, 2013, Ivhan Herrera-Chiang, 31, a former U.S. Border Patrol agent, and Michael Lopez-Garcia, 30, a former state prison guard, were sentenced by U.S. Senior District Court Judge Paul G. Rosenblatt to prison terms of 15 years and 9 years, respectively, for their involvement in a plot to provide sensitive information to drug traffickers and to arrange for the murder of an informant.  Both defendants had previously pleaded guilty to various charges arising from the scheme.

First Assistant U.S. Attorney Elizabeth A. Strange stated, “These defendants engaged in a profound betrayal of the public trust.   The U.S. Attorney’s Office, working with our law enforcement partners, will continue to strive to ensure the integrity of every officer entrusted with the safety of the public.  These sentences send a powerful message that we will not tolerate corruption within the law enforcement ranks.”

"What began as a drug smuggling investigation quickly became more complex when HSI special agents learned a federal agent was misusing his position of trust to facilitate the commission of crimes," said Matt Allen, special agent in charge of ICE Homeland Security Investigations (HSI) Arizona. "While his actions are atypical of the dedication and integrity demonstrated by the vast majority of those who serve, this sentence should nonetheless send a message about the serious consequences facing those who would exploit their positions and violate that special trust.”

FBI Special Agent in Charge Douglas G. Price, Phoenix Division stated, "When those who are entrusted to uphold the law choose to betray the trust of the America people by committing bribery and drug trafficking it tarnishes the badge of those who honorably serve and protect our country.  Today's sentencing illustrates that justice was served in this matter. The FBI will continue to work with of law enforcement partners to combat public corruption at all levels."

“The lengthy sentences given to these defendants are very appropriate given their egregious crimes.  When those entrusted to uphold the law sink to the level of criminals they pursue for financial gain, it is a sad day for those of us in the law enforcement community," stated IRS Criminal Investigation Special Agent in Charge Dawn Mertz.

As  acknowledged  in  their  plea  agreements,   the  defendants  formed  a  “criminal partnership” to earn money by helping traffickers smuggle drugs and aliens into the United States.  As part of this multi-year partnership, Lopez-Garcia personally smuggled nearly two pounds  of methamphetamine into  the country (by hiding the drugs  under his  prison  guard uniform as he crossed through the Port of Entry) and also attempted to smuggle thirty kilograms of cocaine into the country.  Herrera assisted Lopez-Garcia (in return for bribes) by providing him with sensitive information—including sensor maps, combinations to gates located near the Mexican border, computer records concerning prior drug seizures, and the location of Border Patrol units—to which Herrera had access by virtue of his employment as a Border Patrol Agent.

During the final stages of the partnership, Lopez-Garcia attempted to arrange for the murder of a government informant after becoming fearful that the informant might be able to provide incriminating information about his activities.   As part of this plan, Lopez-Garcia obtained confidential information concerning the informant’s identity from Herrera and then relayed this information to his Mexican trafficking associates.

The investigation in this case was conducted by the Department of Homeland Security- Office of Inspector General, Homeland Security Investigations, Homeland Security Investigations-OPR, the Federal Bureau of Investigation, Customs and Border Protection-Office of Internal Affairs, and the Internal Revenue Service, Criminal Investigation.  The prosecution was handled by Dominic Lanza, Assistant U.S. Attorney, District of Arizona, Phoenix.
