Johan Rilz

Johan Rilz is a German interior designer whose murder alongside Mitzi Elliot drives the criminal case against Walter Elliot and, later, becomes the focus of Mickey Haller’s alternative defense strategy. In life, Rilz moved between the private world of wealthy clients in Los Angeles and a concealed past as an informant for the French Judicial Police. In death, the gaps in what investigators knew about him expose how quickly a murder inquiry can narrow around one suspect—and how the victim’s own history can reshape a courtroom account.

Identity and Background

Rilz was a German national who had come to the United States from France. A page from his passport showed that he left France for the United States in March 2003; a French newspaper article about him had appeared one month earlier. By the time of the killings, he had been in the country for about four years and was thirty-five. His public occupation was interior decorating, a role that brought him into the homes and social lives of affluent clients in Los Angeles.

Mitzi Elliot hired Rilz for interior-design work in the fall of 2005, according to Detective Kinder’s testimony. Kinder could not say whether the two had known one another before that. The later revelation that they were lovers therefore changed the significance of what had initially looked like a professional connection. Walter Elliot said that Rilz had been present at dinners, parties, and premieres with him and Mitzi, while Walter believed that Mitzi had represented Rilz as gay. Those details came from Walter’s account, not from an independent record of Rilz’s private life.

The Malibu Murders

Rilz was killed with Mitzi at a secluded waterfront weekend house owned by the Elliots in Malibu. The bedroom was about twelve hundred square feet, with a glass wall facing the Pacific. The killings took place there while Walter and Mitzi’s marriage was under strain: Mitzi had said she intended to divorce him, and Walter suspected she had another partner. The murder weapon was missing, but ballistic testing identified the bullets as having been fired from a Smith & Wesson Model 29 .44 Magnum revolver.

The crime-scene summary placed Rilz near the bedroom doorway and Mitzi by the bed. Investigators proposed that the couple heard someone enter, that Rilz went to the door, and that the killer then moved into the bedroom. Their account also treated the circumstances of Mitzi’s death as possible evidence that she knew her assailant. These were elements of the official reconstruction, not established knowledge of what Rilz saw or understood in his final moments.

Walter’s account to investigators sharply differed from the prosecution’s later claim that he killed the couple in a fit of rage. He said he had gone to the house expecting to confront Mitzi and a lover, but had found her and Rilz already dead. He denied owning a .44 Magnum or any guns, and said he returned to the property after initially driving away, called 911, and waited for deputies. Prosecutors, by contrast, argued that Walter called the deputies after killing them and pointed to forensic evidence that he had recently fired a weapon. The conflicting accounts made the question of who killed Rilz central to the trial.

A Past Left Unexamined

As Haller prepared the defense, he argued that investigators’ attention had shifted almost entirely to Walter after a gunshot-residue test came back positive. In Haller’s view, that narrowed focus left significant parts of Rilz’s background unchecked. No investigator had gone to Germany to look into whether he had enemies there, and Haller argued that the inquiry into Rilz’s life in Los Angeles had also been incomplete. The possibility that he had other powerful or aggrieved acquaintances was a line of investigation Haller raised, not proof that any such person had threatened him.

A report in Le Parisien supplied a more concrete lead. It identified Rilz as a prosecution witness in a major drug case in France and described him making purchases and gathering information from inside a drug ring for the French Judicial Police. Haller linked the article to the man in the murder case with the passport page from the prosecution’s own discovery: the departure date, age, and interior-decorator occupation matched. The disclosure turned Rilz from a seemingly local victim into a former informant whose actions could have made enemies before he came to Los Angeles.

Haller later said he had a French police captain prepared to testify that Rilz had informed on seven dangerous, vindictive men. Two had been released from prison the previous year and had disappeared. Haller suggested they might have been in Malibu around the time of the killings, but the evidence presented here does not establish that they were there or that they killed Rilz. The possibility nevertheless served Haller’s larger contention: investigators had treated Walter as the answer before fully investigating the victim’s connections.

From Victim to Defense Strategy

Haller’s visit to the Malibu house made the physical arrangement of the bedroom part of his defense preparation. He photographed the room for his own reference and studied its door, bed, sight lines, and glass doors opening toward the deck. He regarded the scene as a map that could be read against the prosecution’s reconstruction. Some details remained unknown, including whether the curtains and glass doors had been open during the killings. Rather than resolving what happened, the visit showed Haller where assumptions in the official account might be challenged at trial.

The prosecution’s theory relied in part on the suggestion that Mitzi’s response indicated familiarity with her killer. Haller countered that the reconstruction depended on assumptions about what the victims had heard, seen, or thought. In court, he used the French article and passport to contest the completeness of the investigation and to direct attention toward Rilz’s concealed history. The defense did not need to establish a particular alternative killer for Rilz’s past to matter: it could also support reasonable questions about whether the authorities had pursued other leads.

Rilz’s history thus became both evidence and an argument about investigative method. His work as an informant offered a plausible source of danger, while the lack of a completed inquiry into that history gave Haller grounds to attack the investigation’s tunnel vision. At the same time, using the information risked casting suspicion on a dead man and burdening his family with a defense built around his past. Prosecutor Jeffrey Golantz told Haller that Rilz’s family had returned to Germany after being warned that the defense would portray him as a man who deceived and exploited clients. The family’s absence underscored the human cost of making the victim’s character a trial battleground.

The Family’s Revenge and Narrative Role

After Walter Elliot and Nina Albrecht were murdered, Harry Bosch told Haller that the family of Johan Rilz had taken care of it. Bosch pointed to the recovered bullets: they were nine-millimeter Parabellums with German-made brass jackets and casings, and their profile matched a German-manufactured Mauser C96. That evidence gave Bosch a basis for connecting the later killings to Rilz’s family, but it does not identify individual perpetrators in the material presented here. The revenge also reframed Rilz’s earlier murder: the investigation Haller had urged authorities to pursue became part of the story’s aftermath.

Rilz remains a character reconstructed through other people’s accounts rather than through a sustained personal viewpoint. Walter’s changing story, the prosecution’s theory, the crime-scene reconstruction, the French newspaper report, and Bosch’s later explanation each disclose a different part of his life and death. That structure makes the uncertainty around Rilz consequential: his profession first explains how he entered the Elliots’ household, his affair with Mitzi supplies the immediate context for Walter’s confrontation, and his former informant role opens a wider history that the initial investigation had missed. Even after his death, the struggle over who Rilz was—and which parts of his past deserved attention—continues to shape the case and its consequences.
