3 Orange County, California Mexican Mafia Members & 28 Associates Indicted on Federal Racketeering, Murder and Drug Trafficking Charges

The federal indictment incorporates two cases involving reputed Orange County Mexican Mafia chief Johnny Martinez, 46, that have lingered in Orange County Superior Court and encountered legal roadblocks that jeopardized the prosecutions. One murder case against him was thrown out by a judge, and another was on the verge of dismissal based on a new state law requiring more active participation by a co-defendant in a killing.

Now the reputed gang boss faces an assortment of federal allegations detailed in the 106-page indictment that names 30 other defendants. Federal prosecutors allege the racketeering conspiracy began in 2016 and continued through this year. The indictment alleges multiple murders, extortion, robbery, and drug trafficking. Local authorities say Martinez rose to power following the 2018 death of Peter Ojeda in prison, where he was serving a 15-year sentence.

Like Ojeda, Martinez is accused of running the gang from jail and prison, ordering hits on rival gangs and drug dealers in and out of custody who fail to “pay taxes” through various means of communication such as smuggled contraband phones and using girlfriends and wives to convey messages on the outside.  During the yearslong investigation, dubbed “Operation Night Owl,” authorities conducted undercover purchases of meth and heroin from O.C. Mexican Mafia associates who were allegedly selling the drugs on behalf of Johnny Martinez and the gang.

In addition to these alleged violent acts, law enforcement investigated the OC Mexican Mafia’s methamphetamine and heroin trafficking activities on the streets, as well as in the prisons and jails. Authorities conducted multiple undercover purchases of methamphetamine and heroin from OC Mexican Mafia associates who were selling narcotics on behalf of Johnny Martinez and the OC Mexican Mafia.

Acting on behalf of Martinez, Gregory Munoz, who was in prison at the time, is accused of ordering a robbery that led to the death of 35-year-old Robert Rios in Placentia on Jan. 19, 2017, the indictment alleges. Ysrael Jacob Cordova, Ricardo Valenzuela, and Augustine Valazquez, who was convicted of murder in the case in state court, were allegedly ordered to carry out the robbery that turned deadly.

Charles Frederick Coghill, who was also charged in state court in connection with Rios’ murder, was a key witness for the prosecution in Velazquez’s trial. Coghill was not named in the federal complaint.

Coghill drove Cordova, Velazquez, and Valenzuela to Rios’ residence in the 900 block of Vista Avenue, state prosecutors said in Velazquez’s trial. Velazquez was shot in the leg as Rios fought back, and Coghill later dropped Velazquez off at his home, where he called a friend to give him a ride to a hospital in San Diego, prosecutors said in the trial last year.

Munoz had a subsequent falling out with the gang and he was stripped of his shot-caller status in March 2017, the federal complaint alleges. Sources have said that Munoz and Martinez had a personal falling out when Johnny Martinez failed to tell Munoz his girlfriend was cheating on him, and Martinez felt disrespected by Munoz’s griping about it. On March 28, 2017, Martinez directed the gang to attack Munoz in Calipatria State Prison, the federal indictment alleges.

Munoz was slashed with shivs by gang members on April 6, 2017, the complaint alleges. Meanwhile, Martinez and others named in the indictment set up methamphetamine and heroin deals, but unknown to them, two of the dealers were confidential informants, according to the complaint.

In August 2017, Martinez, Omar Mejia, and Robert Martinez — no relation to Johnny — conspired to kill Munoz, who was then out of custody, the indictment alleges. Robert Martinez and Frank Mosqueda attacked Munoz, with Mosqueda shooting Munoz multiple times in the back, according to the indictment. But Munoz somehow survived the ambush.

On Aug. 20, 2017, Martinez ordered the killing of Richard Villeda “for stealing money and drugs from defendant Martinez,” the indictment alleges. Villeda was shot to death just after midnight on Aug. 21, 2017. in the 800 block of East Culver Avenue. Defendants Kevin Trejo, James Mendez, and Mike Escobar “lured” the victim into a vehicle with Escobar behind the wheel, the indictment alleges.

The indictment also details confrontations with a tire shop owner for dealing drugs out of the business without permission and running protection rackets for marijuana dispensaries. Defendant Robert Aguirre was accused of “greenlighting” one unnamed man for an attack in October 2017. The victim was shot as he ran from gang members on Oct. 24, 2017.

The indictment alleges that on one occasion in November 2017, defendant Luis Heriberto Vasquez handed over $1,625 in street taxes from local gang members to Martinez, who presided over the transaction from a smuggled-in cell phone. That same month, Martinez and defendant Dennis Ortiz arranged to smuggle contraband cell phones into Salinas Valley State Prison, which were sold for $1,000 apiece, the indictment alleges.

On Dec. 1, 2017, a Theo Lacy Jail inmate was slashed at the direction of the gang, the indictment alleges. That same month, Ortiz allegedly ordered another man “be killed for warning other gang members of violations that were pending against them,” the indictment alleges.

Another Mexican Mafia-directed attack was carried out on Christmas Day, 2017, the indictment alleges. On New Year’s Day, 2018, Martinez and Mejia allegedly used the Signal app to discuss killing another defendant, Michael Cooper, while in custody at Calipatria State Prison, the indictment alleges. Cooper’s sin was ordering an attack on another gang member that wasn’t authorized by Martinez and for “being suspected of causing a police raid against” the gang, according to the indictment.

Cooper was attacked with shivs on Jan. 5, 2018, but survived the assault, according to the indictment.

Robert Martinez, along with defendants Robert Amezcua and Mher Darbinyan, aka “Hollywood Mike,” attempted to kill Cooper again, “stabbing him in the face and neck area” with a shiv, the indictment alleges. Another inmate in Theo Lacy had his throat slit and was “stomped” on July 29, 2020, at the behest of Johnny Martinez for “threatening to discuss the Mexican Mafia with law enforcement,” the indictment alleges.

The attempts by Orange County District Attorney’s Office prosecutors to make cases against Johnny Martinez and the others in the Robert Rios murder and attempted murder of Munoz have been beset with problems. After charging them, prosecutors went to a grand jury for an indictment in 2018, but it was thrown out for procedural errors in the presentation of evidence.

The defendants were charged again and were ordered to stand trial following a preliminary hearing. But Orange County Superior Court Judge Patrick Donahue granted a motion preventing prosecutors from mentioning Johnny Martinez or the conspiracy to order the hit on Rios because the judge determined that a gang expert from the Orange County Sheriff’s Department lied about his training as part of a wide-ranging evidence-booking scandal in the department. Later, Donahue threw out the murder case against Martinez for lack of evidence, and defense attorneys have been seeking similar motions in the Rios case.

With those cases faltering, the first indication that the U.S. Attorney’s Office was stepping into the fray came on April 4, when county prosecutors moved to dismiss an attempted murder case against Robert Martinez — knowing he was being named in the federal indictment.

The indictment alleges that the Mexican Mafia, also known as La Eme, was comprised mostly of senior members of Latino street gangs who came together to control and profit from the activities of other Latino gangs operating in Southern California and within the California penal system. It is alleged that the Mexican Mafia members divided control of various areas in Southern California, with the member in control of a specific area controlling the criminal activities in that territory and receiving “taxes” paid by gangs to allow them to deal drugs in that area.

In addition to this widespread “tax” collection, it is alleged that the OC Mexican Mafia directly engaged in drug distribution in and out of prisons and jails. The indictment also alleges that the OC Mexican Mafia maintained authority over Latino street gangs through murder, attempted murder, and violent assaults with weapons including firearms.

“Cases targeting criminal enterprises like the Mexican Mafia require close collaboration with our local and federal partners and employ a variety of sophisticated techniques to overcome their evasive tactics,” said Kristi K. Johnson, the Assistant Director in Charge of the FBI’s Los Angeles Field Office. “The Mexican Mafia in Orange County controls the majority of local gangs and rules by threatening violence and exacting violence on their enemies or against their own members who don’t follow strict rules. This indictment is the latest in our continuing joint efforts to target gangs and drug networks that fuel the violence in our communities.”

The indictment alleges that in or around 2016, and continuing to at least in or around April 2022, defendants Johnny Martinez, Robert Aguirre, and Dennis Ortiz were the OC Mexican Mafia members in charge of criminal activities in Orange County and within Orange County jail and prison facilities. Defendants Omar Mejia, Miguel Jose Alvarado, Luis Heriberto Vasquez, Michael Cooper, and Abraham Guajardo held positions of shot-callers or mouthpieces for Martinez, Aguirre, and Ortiz. Defendant Robert Martinez held a position of authority within the Orange County Jail as Johnny Martinez’s representative. Defendant Brenda Vanessa Campos Martinez served as a secretary for Johnny Martinez, and defendant Danielle Canales served in a similar capacity for Johnny Martinez and Cooper. 

Violent crimes alleged against the OC Mexican Mafia include:

The Jan. 19, 2017, armed robbery and shooting death of R.R.;
The Aug. 21, 2017, shooting death of R.V., who was shot seven times in the back of the head and body, and left dead on the street in Orange;
The Aug. 5, 2017, attempted murder of defendant Munoz, who had fallen out of favor with the OC Mexican Mafia and was shot seven times;
The Dec. 1, 2017, attempted murder of D.D., a representative of a Latino street gang, who was allegedly abusing his power and authority within the OC Mexican Mafia enterprise;
The Dec. 12, 2017, attempted murder of E.O., an OC Mexican Mafia associate incarcerated at Calipatria State Prison, who was believed to have violated the OC Mexican Mafia’s code by warning individuals that they were targeted for violence by the OC Mexican Mafia, and who suffered multiple injuries, including puncture wounds to his torso;
The Dec. 25, 2017, attempted murder of R.M. for showing disrespect to defendant Johnny Martinez;
The July 29, 2020, attempted murder of F.B., a member of an Orange County Latino street gang incarcerated at the Theo Lacy Facility, who was targeted because he purportedly claimed that he would speak to law enforcement about the Mexican Mafia, and whose throat was slit; and
The two murder attempts on Jan. 5, 2018, and Dec. 31, 2019, of defendant Cooper, who had fallen out of favor with defendants Johnny Martinez and Aguirre, and who in one incident was stabbed multiple times in the head and back area, and in the second was cut in the throat and face.

“The Santa Ana Police Department is committed to working alongside local, state, and federal law enforcement partners to ensure that violent, career criminals are incarcerated and are brought to justice,” said Santa Ana Police Chief David Valentin. “Today’s operation was a result of years of dedicated investigation into some of the most dangerous gang members that plague our communities.”

“Today’s arrests are the culmination of a multi-year investigation that IRS-CI is proud to be a part of”, said IRS Criminal Investigation Special Agent in Charge Ryan L. Korner. “The subjects of this investigation engaged is some of the most horrific acts imaginable, and we are glad to have done our part to help end their corrupt influence over our community.”

Out of the 31 defendants charged in the indictment, 21 were already in custody, and nine were arrested last night and this morning. Those arrested today are expected to be arraigned this afternoon in United States District Court in Santa Ana, and those already in custody will make initial appearances once each defendant is in federal custody.

The RICO statute provides for a maximum penalty of 20 years imprisonment for acts performed as part of the criminal organization. The VICAR statute provides for a mandatory sentence of life imprisonment for murder, a maximum sentence of 20 years for assault with a dangerous weapon, a maximum sentence of 10 years for attempted murder, and a maximum sentence of three years for attempted assault with a dangerous weapon. The charge of possessing, using, carrying, and discharging a firearm in furtherance of/during and in relation to a crime of violence carries a maximum sentence of life, with a mandatory sentence of at least five years and up to 10 years.
