Epifanio Galindo and Klaus Haas’s investigative relationship

Epifanio Galindo and Klaus Haas’s investigative relationship is a prolonged contest between an investigator pursuing a suspect and a suspect who resists both questioning and the meaning assigned to the evidence. Epifanio’s inquiries connect Haas to Estrella Ruiz Sandoval’s murder and lead to a formal arrest, but the case never resolves into a definitive account: physical evidence is compromised, and Haas later names another man as the killer of women in Santa Teresa and nearby areas. Their encounters show the pressure of an investigation conducted amid recurring violence, where suspicion can gather force without becoming proof.

First Encounter and Emerging Suspicion

Epifanio first visits Haas’s computer store while Haas is speaking with a customer. The scene gives the investigator time to observe the business and its employees before he can question its owner. A photograph of Estrella Ruiz Sandoval changes the encounter: Haas studies it without taking it, makes a peculiar expression, and says he does not think he knows her, while conceding that many people pass through the store. Epifanio introduces himself as a police officer and shakes Haas’s hand, registering the man’s physical strength. The exchange leaves Epifanio suspicious, but it does not establish that Haas knew Estrella or killed her.

The investigation proceeds through further inquiry into Haas’s business and background. Epifanio learns that Haas is German-born, became an American citizen, and runs stores in Santa Teresa and Tijuana. A police record obtained through a contact in El Adobe adds earlier allegations and charges, including an accusation of attempted rape that was later dropped, as well as charges related to indecency and soliciting prostitutes. These details shape Epifanio’s suspicions, but they are not proof of the Santa Teresa murder. The distinction between a troubling history and evidence in the case remains important as the inquiry advances.

Confrontation and Arrest

On a later visit, close to midnight, Epifanio questions Haas at his home in Colonia El Cerezal. Haas pours himself whiskey while Epifanio asks whether he has an alibi for the night Estrella was killed. Epifanio says two witnesses place Haas with the victim, but does not identify them. When he asks to look around the house, Haas refuses and demands a warrant. Epifanio leaves after directly accusing him of killing Estrella and possibly other women. The exchange makes their relationship openly adversarial: Epifanio presses the accusation, while Haas insists on the limits of what the police may do without legal authorization.

A search of Haas’s downtown store reveals a basement room containing a bed, a mirror, and a candleholder; one bathroom is kept clean while another is strikingly dirty, and an unlit bulb appears to have been unscrewed. These details prompt attention but do not independently establish what occurred there. Two days later, officers arrive with warrants authorizing Haas’s arrest as a suspect in the rape, torture, and murder of Estrella Ruiz Sandoval, and searches of his home and two stores. They find him at home and take him to Precinct #1. The inquiry has moved from surveillance and confrontation to formal custody, but the arrest remains an accusation under investigation, not a verdict.

Interrogation and Fragile Evidence

The interrogation lasts four days. Epifanio participates alongside officers from the Santa Teresa police and judicial police, with the police chief, two judges, and a senior state prosecutor also present. Haas has two episodes of uncontrollable rage and must be restrained. He eventually acknowledges that Estrella visited his store three times, a disclosure that establishes contact but does not by itself explain the visits or demonstrate his responsibility for her death.

Investigators find traces of blood on a blanket and on the basement floor. Estrella’s relatives provide samples for DNA testing, but the samples are lost before reaching the laboratory in San Diego. Haas says the blood may have come from a woman with whom he had sex during menstruation; investigators have no surviving test result in this account to confirm or disprove that explanation. The search also uncovers a machete and two large hunting knives, but they are clean, with no blood or fabric traces. The physical evidence therefore raises questions without supplying a conclusive link between Haas and Estrella’s murder.

Epifanio’s investigation takes place against a broader pattern of unresolved deaths and uncertain identification. In a separate case, a murdered woman found in a field is never identified; in another, the clothing of an unidentified girl disappears before police arrive, and later efforts to identify her fail. Such episodes do not prove anything about Haas, but they show the investigative conditions surrounding his case: victims can remain nameless, evidence can be lost or compromised, and official attention can yield reprimands rather than answers. The uncertainty surrounding Haas is part of a wider failure to establish reliable conclusions about the killings.

Custody, Conflict, and Competing Accusations

In jail, Haas disturbs other prisoners with talk of a giant who will come to kill those who have wronged him. A guard reports that Haas also uses racist insults and refuses to bathe; prison officials, meanwhile, have kept him from using the showers until receiving instructions from senior authorities. When Epifanio visits, Haas at first does not recognize him, appearing thinner and exhausted. Epifanio offers the prospect of transfer to a newer prison in Hermosillo if Haas pleads guilty. Haas recognizes him and rejects the pressure. Their exchange shows that the investigation continues inside detention, where a possible confession is entangled with the conditions and leverage of imprisonment rather than presented as an established admission of guilt.

Later, Haas identifies Antonio Uribe as the killer of women in Santa Teresa and its surrounding area. He says he met Uribe once, but the account does not establish that the claim is true. The allegation shifts attention from the accused man to another named suspect without resolving the case against either. Epifanio and Haas’s investigative relationship thus remains suspended between accusation and competing claims: Epifanio has pursued Haas through interviews, searches, and arrest, while Haas’s counter-accusation leaves the larger pattern of killings—and the reliability of any single explanation—open.
