Santa Teresa’s maquiladora industry and labor

Santa Teresa’s maquiladora industry and labor form a visible boundary between the city’s promise of employment and the unequal conditions that organize daily life around its factories. The plants draw workers, most of them women, into industrial parks linked to cross-border production; yet their surrounding roads, transit, lighting, drainage, and public services lag behind the city’s growth. As the novel follows workers’ commutes and the discovery of women’s bodies in industrial or peripheral spaces, the factories become part of a larger geography of labor, vulnerability, and institutional indifference—not a single explanation for the violence.

Industry and the expanding city

The maquiladoras appear on the horizon as Santa Teresa’s industrial landscape, surrounded by neighborhoods that expand beside them. In one view of the city, industrial warehouses punctuate the distance, while the southern outskirts include rail lines, informal soccer fields, shacks, a garbage-filled gully, and districts described as having grown up impaired or incomplete. Industrial parks themselves are encircled by slums. The city seems to be growing by the second, but growth does not arrive as evenly distributed infrastructure: factories and housing press against one another, and the urban edge is made up of both employment sites and places poorly served by basic amenities.

A more focused account locates four appliance-assembly maquiladoras near a dump between Colonia Las Flores and the General Sepulveda industrial park. New silver-painted electrical towers supply the plants; nearby, shacks stretch toward train tracks and Colonia La Preciada. Workers arrive by bus from different neighborhoods, get off at a plaza, and then walk along dirt roads to factory gates, where guards check their passes. Only one of the four plants has a cafeteria. At the others, workers eat beside their machines or gather in corners until the lunch siren sends them back. Most of the workers are women. The scene makes industrial production concrete through its routines—transport, security checks, meals, and shifts—while showing how little separation there is between the production system, the dump, and nearby precarious housing.

Work, migration, and household survival

The factories are not merely backdrops to the city’s growth: they structure household schedules and the means by which families try to secure a more stable life. Penelope Mendez Becerra’s mother works at Interzone-Berny, as does Penelope’s older sister, Livia. Their father had left years earlier, after migrating north with the family from Hidalgo in search of work, and later crossed the border in the hope of earning enough to bring them to California. The family never heard from him again. His uncertain fate—whether he had started another life or died during migration—remains unresolved, while the responsibility for maintaining the household falls on the women who stay behind.

After a drunken neighbor tried to assault Livia, her mother confronted him with a knife in her apron and warned him not to harm her daughter. She did not rely on his promise to change. Instead, she worked long hours, took overtime, and sold sandwiches to coworkers until she could rent a small, solid house in Colonia Veracruz, with two rooms and a door that could be locked. The move meant a longer walk to Interzone-Berny, but a more secure home. Her labor extended beyond the factory: she sometimes worked two shifts and stayed up late preparing sandwiches for the next day’s coworkers. The novel presents this effort as resourceful and sustaining, but also as a heavy burden borne by a mother whose options are constrained by low-wage work, migration, and the need to care for her children.

The family’s work arrangements shape the children’s lives as well. Livia takes responsibility for her siblings before she, too, begins working at the factory at fifteen. Her brother leaves school at fourteen, briefly works at Interzone-Berny, and is dismissed after warnings that he is not fast enough; his mother then finds him a job at a neighborhood bakery. Penelope, the youngest, remains in school. The contrast is pointed: factory labor absorbs the older children and adults into its schedule, while Penelope’s schooling marks her as the one child whose daily life has not yet been organized by paid work.

Commuting and uneven infrastructure

For factory workers, the journey between work and home is shaped by the city’s uneven infrastructure. Margarita Lopez Santos works the third shift at K&T, in the El Progreso industrial park near the Nogales highway. She is considered dependable and is known to have arrived for work on time. On the night she disappears, she finishes at five in the morning and begins the walk home around five-thirty. The route and its timing can be roughly reconstructed, but not the moment when she vanishes: it is still dark, and the surrounding area is poorly lit.

The account details the conditions along her possible route without turning them into a proven explanation for her disappearance. Most homes in the northern part of Colonia Guadalupe Victoria have no electricity. Apart from the road leading to the Nogales highway, roads out of the industrial park lack adequate lighting, paving, and drainage. Industrial waste flows toward Colonia Las Rositas, where it forms a muddy lake that dries white in the sun. A truck selling coffee, soft drinks, and sandwiches serves workers entering or leaving the WS-Inc. maquiladora, most of them women. Margarita may have passed it; the narration cannot establish whether she did. She crosses the highway and turns into Guadalupe Victoria, a walk of less than half an hour before reaching San Bartolome, where she lives. Her disappearance interrupts an ordinary, approximately fifty-minute commute and leaves the specific circumstances unknown.

Another case shows that work-related vulnerability is not confined to the route home. Guadalupe Rojas, an employee at the recently built File-Sis maquiladora on the road to Nogales, is killed at the entrance to her building rather than on the journey from the factory. Her boyfriend is arrested after trying to flee, and the stated motive is jealousy. By locating this killing at home and identifying a suspect, the novel distinguishes it from cases in which women remain unidentified or their deaths unexplained. The factory setting is part of the social world in which the cases unfold, but it does not make every crime the same or establish a single cause.

Production, waste, and cross-border commerce

The industrial economy is connected to the border through the movement of goods as well as people. On the American side, Adobe is described as a former adobe factory that has become a stretch of houses and appliance stores along a main street, ending at the border post. At the Mexican crossing, travelers face document checks and forms, while the high fence between the countries remains in view. The border procedure gives a physical and administrative form to a nearby system in which factories assemble products for wider markets.

Santa Teresa’s industrial economy also appears alongside other sources of money and movement. Chucho Flores describes a city with factories and maquiladoras, a low unemployment rate, a cocaine cartel, a constant influx of workers from other cities, and Central American immigrants. He also identifies an urban infrastructure unable to support the pace of demographic growth. His account places employment and poverty, official systems and illicit economies, side by side; the industrial city is neither simply prosperous nor simply destitute. The contrast is sharpened by the question of time: the city is growing faster than its infrastructure and institutions can keep pace with it.

A factory executive’s response to a body found in the dump exposes another, more direct crossing between industrial authority and policing. The dump contains both refuse from nearby shacks and waste from the maquiladoras. When a woman’s body is found there, a plant manager alerts the authorities, and three company executives meet the police at the site. One executive asks that the body be removed promptly; after a policeman assures him that matters will be handled, money is passed to him. The incident does not establish that the factory caused the killing. It does show how industrial representatives, police, and the treatment of an unidentified dead woman occupy the same scene, with the transaction suggesting that routine accountability can be displaced by private payment.

Labor and the femicide crisis

The novel repeatedly places factory work close to women’s disappearances and deaths, but it preserves distinctions among what is known, what officials claim, and what remains unanswered. In one case, a worker at a Santa Teresa radio station is murdered after leaving a restaurant. Her station and newspaper explain the killing as a failed robbery, a possible crime by a drug user, or perhaps an attack by a Central American veteran trying to raise money to travel north. There is no autopsy, at the family’s request, and the ballistic analysis is never made public before being lost in transit between the courts of Santa Teresa and Hermosillo. These explanations remain competing theories, not settled findings; the loss of evidence leaves the death harder to investigate.

A different institutional pattern appears when Emilia Mena Mena’s boyfriend becomes the main suspect. He has already left when police search his family’s home. His father and brothers are detained briefly, officers pursue an address in Ciudad Guzman, and the investigation finds no trace of him. The case stays open but is soon forgotten. Elsewhere, Juan de Dios Martinez is taken off the Penitent case and assigned to a series of armed robberies. He is told that the earlier case is not formally closed, but that the suspect appears to have vanished, the investigation has stalled, and a limited number of investigators must prioritize other matters. The episode reveals how scarce police resources can redirect attention even when a case is nominally still active.

Organized responses to the killings develop alongside these investigative failures. In January 1996, Women of Sonora for Democracy and Peace holds a press conference in Santa Teresa about the degrading treatment of victims’ families and presents letters intended for the state governor and the attorney general. Neither letter receives a reply. The local branch grows from three members to twenty activists and supporters, but that increase does not yield a response from the officials addressed. The contrast between the organization’s efforts and official silence makes the crisis a matter not only of violence but also of whose accounts and demands receive institutional attention.

Significance

Santa Teresa’s maquiladora system is presented through specific working arrangements and landscapes: women assembling products, commuting before dawn, eating near machinery, and supporting families through factory shifts and additional informal labor. Its geography brings industrial parks into contact with shacks, unpaved roads, dumps, and neighborhoods with inadequate public services. These are not interchangeable conditions, nor does the novel claim that factory employment alone produces the killings. Rather, industrial expansion supplies the setting in which the unequal distribution of safety and infrastructure becomes legible.

Cross-border commerce and local precarity coexist throughout this portrait. Finished goods move through an economy that reaches beyond the border, while workers’ daily journeys depend on poorly lit streets and limited transport. In this environment, a missing worker’s route can be reconstructed down to shift times and likely streets without revealing where she disappeared; an unidentified woman can be found amid industrial and household refuse while the institutions responsible for her care and investigation remain compromised. The factories thus connect the city to wider circuits of production, but they do not resolve the local failures surrounding labor, public safety, and recognition.
