Miroslava Breach Velducea (7 August 1962 – 23 March 2017) was a Mexican investigative journalist for La Jornada and Norte de Juárez in Chihuahua City, Mexico known for her reportage of human rights violations, drug trafficking, and government corruption.

[1] Miroslava Breach Velducea was born on 7 August 1962 in Chínipas in the Sierra Tarahumara region of the Mexican state of Chihuahua.

[7] On 4 March 2016, La Jornada published a piece by Breach that exposed that cartel members had infiltrated mayoral candidate lists for the Institutional Revolutionary and National Action parties in rural, mountainous drug corridors of Chihuahua.

On 5 November 2016, she announced that in six years of government, Duarte had operated a private network of friends and family that embezzled 900 million pesos.

[9] One of Breach's most important exposures was that of the Mexican Attorney General's investigation into the existence of clandestine graves being used in El Largo Maderal.

Beginning in August 2016, she reported on the displacement of indigenous peoples in Chihuahua by organized crime, namely by a group called "Los Salazares" that she believed was also tied to illegal logging.

[1] On 23 March 2017 at 7:06 a.m. CST, Breach was shot eight times by a gunman at the intersection of Rio Aros and José María Mata as she drove her Renault Duster SUV away from her home in the Granjas neighborhood, Chihuahua City to take her 14-year-old son to school.

"El 80" was identified as Carlos Arturo Quintana,[13] son of César Raúl Gamboa Sosa (who had been killed three days before Breach's murder)[4] and leader of the crime syndicate La Línea, a division of the Juárez Cartel.

Governor Javier Corral Jurado and his private secretary Francisco Muñoz visited Breach's children to comfort them and declared a three-day mourning period for her.

[1][9] A month after Breach's murder, her sister, Rosa María, implored authorities to spare little expense to acquire justice for Miroslava.

[14] On 11 October 2017, Corral confirmed information that had leaked that day to the press by declaring that the police investigation into Breach's murder had determined that the criminal organization "Los Salazares", a division of Gente Nueva, an armed wing of the Sinaloa Cartel, had masterminded the killings.

Federal agents pored through video footage to trace the route of the vehicle and the assailant's escape in a getaway car driven by two other yet unidentified men.

Breach refused to disclose a source, alleging that she came to her own conclusions and confirmed to the spokesperson that she had not met with the PAN mayor of Chínipas at the time, Hugo Amed Schultz, about Salazar.

Chihuahuans, who believed that César Duarte Jáquez had not been sufficiently punished and were upset that Governor Corral had been on vacation in Mazatlán only two days before, began to demand justice for Breach and the many other journalists who had been killed in Chihuahua.
