Rigoberto Frias

Rigoberto Frias is a medical examiner in Santa Teresa, known to his colleagues as meticulous and skillful but presented as a solitary figure. His work and routines place him among the city’s institutions confronting repeated killings of women, while the novel sets the examiners’ restrained professional silence against the police culture surrounding them.

Identity and Background

Frias is thirty-two and originally from Irapuato. He worked in Mexico City before abruptly leaving that job for reasons the narrative does not explain. He has lived in Santa Teresa for two years, having been hired on the recommendation of a former classmate of Emilio Garibay. Alongside his work as a medical examiner, Frias serves as a teaching assistant at the medical school.

He lives alone in a small, tastefully furnished apartment in Colonia Serafin Garabito. He has many books and almost no friends; outside class, he rarely speaks with his students, and he has no social life in university circles. These details define him through a contrast: he is professionally present in the university and forensic institutions, yet personally withdrawn from their social life.

Work and Professional Routine

Frias’s colleagues regard him as careful and capable, qualities that matter in a city where determining how a woman died may be possible even when her identity, the circumstances of her death, or the larger pattern remain unresolved. The novel gives no individual investigation to Frias alone, but places him within the forensic apparatus that examines bodies and produces findings alongside the police’s statements and assumptions.

His professional routine is shared with Garibay and Juan Arredondo. On some occasions, at Garibay’s direction, the three examiners meet for breakfast in the early hours at Runaway, a twenty-four-hour American-style coffee shop. The clientele includes hospital orderlies and nurses, ambulance drivers, patients’ relatives and friends, sex workers, and students—people whose nights have brought them into the same small orbit.

At Runaway, Frias usually orders little, at most a doughnut. Arredondo has cake with ice cream, while Garibay orders steak, despite Arredondo’s warning that it is bad for his joints. Their differences emerge in sparse gestures and habits rather than conversation: Arredondo studies the backs of his hands, Frias looks at the table or the ocher ceiling, and Garibay watches the street. The examiners generally sit in silence, absorbed in what Garibay calls the knowledge of a job well done.

A City of Evidence and Uncertainty

The killings that frame Frias’s work are represented through sharply specific forensic facts, but those facts do not always yield identification or certainty. In one early case, Esperanza Gomez Saldana, thirteen, is found in a vacant lot in Colonia Las Flores. The medical examination establishes that she was strangled and subjected to sexual violence, while her identity is initially unknown. Five days later, Luisa Celina Vazquez is also found strangled; police arrest two men in connection with her death, then try to link one of them to Esperanza’s killing. The narrative’s account of these investigations distinguishes the findings of an autopsy from the police’s efforts to assign blame.

Other cases expose how incomplete the record can remain. A woman found in a school field is never identified. The medical examiner estimates her age at twenty-three to twenty-five and gives her height as five feet seven inches, but cannot settle whether chest wounds or a possible skull fracture caused her death. A skeleton found in a field belonging to the Hijos de Morelos farming cooperative is established as a woman’s remains, but the time and manner of death cannot be fixed; the police statement instead speculates that she may have been killed elsewhere and brought there. Such scenes make forensic work indispensable while showing its limits: a report can describe a body without recovering a name or a dependable account of how it came to be there.

Institutional Contrast and Narrative Role

The examiners’ silence at Runaway is set against the breakfast conversations of police officers at Trejo’s, where jokes demean women and turn violence into casual humor. The contrast is not a claim that Frias personally confronts or rebukes that culture; the evidence presents him as quiet and withdrawn. Rather, his placement within the professional routine of examination gives the novel a counterpoint to the police banter: the dead women’s bodies are objects of forensic work even as the surrounding culture makes their lives and deaths vulnerable to dismissal.

Frias remains a secondary, lightly drawn character, and the narrative does not supply a personal resolution or a later outcome for him. His significance lies in the precision of this limited portrait: a solitary examiner, a doughnut at an early breakfast, averted eyes, and a shared professional silence. Against the city’s expanding industrial landscape and its persistent killings, that routine suggests the labor of attending to evidence without pretending that evidence can answer every question.
