Jose Miranda Jr.’s attorney cited his work and caregiving duties, while prosecutors argued the circumstances of his brother’s death made release unsafe.

FRESNO, Calif. — A judge ordered a 23-year-old Selma man to remain in custody after he pleaded not guilty to murdering his younger brother, rejecting a defense request for release that emphasized his job and his role helping care for younger siblings while his parents worked.

The Sept. 28 hearing turned an otherwise routine argument over pretrial release into a sharply contested discussion about the Miranda family itself. Jose Miranda Jr. is accused of killing his 19-year-old brother, Diego Miranda, at the family’s home near Selma on Sept. 21. Defense attorney Jason Olson argued that Miranda had been working 20 to 30 hours a week and regularly helped look after younger brothers. Deputy District Attorney Adam Christopherson responded that Diego was himself one of Miranda’s younger brothers. Superior Court Judge Stephanie Negin ultimately found that the allegations raised concerns about danger to both the public and Miranda’s family and declined to release him.

The ruling came one week after the fatal encounter at a home in the 11000 block of East Saginaw Avenue. According to the Fresno County Sheriff’s Office, dispatchers received a report of an injured person shortly before 11 a.m. Deputies found Diego Miranda suffering from stab wounds, and he was pronounced dead at the scene. Homicide detectives and crime scene technicians responded to gather evidence and statements. Jose Miranda Jr., who remained at the property, was arrested and later booked into the Fresno County Jail on a murder charge. Authorities have not publicly established a motive for the killing.

Additional details emerged in court that were not included in the sheriff’s initial announcement. Prosecutors said the brothers were at the residence while their parents were taking a younger child to school. Christopherson alleged that Miranda attacked Diego with a large knife that he described in court as a “Rambo-style knife.” The sheriff’s office had previously said only that Diego suffered stab wounds. The prosecution’s account remains an allegation and has not been tested at trial. Miranda has pleaded not guilty, and the defense has offered a different account of what preceded the violence.

Olson told the court that there had been a confrontation between the brothers and argued that the alleged violence should be viewed as an isolated event rather than evidence that Miranda poses an ongoing danger to the community. He proposed conditions that could have included pretrial supervision, GPS monitoring and anger-management programming. The request put the focus not only on the criminal allegation but also on the defendant’s ties to the household, his work history and the practical responsibilities he had before his arrest. Those factors can be raised by defense lawyers when asking a court to release a defendant while a case is pending, but the judge was not persuaded that they outweighed the safety concerns described by prosecutors.

Christopherson focused on the contradiction he saw in presenting Miranda’s history of caring for younger siblings as a reason for release. The prosecutor called that argument an “appalling representation” because the victim was Miranda’s younger brother. Prosecutors also argued that Miranda posed both a public-safety risk and a risk of fleeing. Negin agreed with the state’s safety argument, saying the facts presented by prosecutors supported concern for the community and for members of Miranda’s own family. The ruling did not determine whether Miranda committed murder. It addressed whether he should remain in custody while the charge proceeds through Fresno County Superior Court.

The hearing also brought competing versions of what happened immediately after the stabbing into the public record. According to Christopherson, when relatives returned to the residence and asked what had happened, Miranda initially referred to a rabid animal and later asserted self-defense. The defense, meanwhile, pointed to a confrontation between the brothers without publicly detailing what allegedly led to it. Authorities have not announced a motive, and the available public reports do not establish what started the dispute, whether either brother made threats before the encounter or what evidence investigators believe supports or contradicts a claim of self-defense.

The sheriff’s office said the brothers lived at the residence with their parents and were alone there when the fatal encounter occurred. A sheriff’s spokesperson said deputies had been called to the property before, but officials had not previously encountered anything there approaching the seriousness of the Sept. 21 case. Investigators have not publicly described those earlier calls in detail or said whether they involved either brother. That distinction is important as the case moves forward: prior police activity at an address does not, by itself, establish a history of violence between the people involved in a later criminal case.

The sequence of events developed over several days. Diego was found dead Sept. 21. The sheriff’s office publicly identified Jose Miranda Jr. as the arrested suspect and Diego as the victim on Sept. 23. Local reporting the following day said prosecutors had filed a murder case, while Miranda’s initial court appearance had been delayed. He entered his not-guilty plea Sept. 28, when attorneys argued over whether he should remain jailed. The defense emphasized work, family responsibilities and proposed monitoring; the prosecution emphasized the homicide allegation, the circumstances described in court and what it viewed as continuing risks.

The case remains at the accusation stage, meaning prosecutors still bear the burden of proving the murder charge beyond a reasonable doubt. The release ruling does not amount to a finding of guilt, and the prosecution’s description of the stabbing has not yet been subjected to a trial. The defense will have the opportunity to challenge the government’s evidence, question witnesses and present its own account. Among the central unresolved issues are what triggered the encounter, how prosecutors intend to address the defense’s assertion that there was a confrontation and what physical or testimonial evidence exists concerning Miranda’s reported claim of self-defense.

Authorities have disclosed only limited information about Diego Miranda beyond his age, hometown and relationship to the defendant. The sheriff’s office identified him as a 19-year-old Selma resident. Public reports have focused primarily on the investigation and the court proceedings rather than on his life outside the case. Officials have also avoided publicly announcing a motive, saying that more about the brothers’ relationship and the events before the stabbing would be expected to emerge through the court process. That leaves a substantial part of the case unresolved even as the basic timeline of the arrest and arraignment has become clearer.

The next publicly reported milestone was a Nov. 4 court appearance, but the sources reviewed for this story do not establish what occurred that day. No later plea, trial date or substantive ruling could be independently confirmed. Miranda’s last verified plea remains not guilty, and the murder charge remains unresolved as the case proceeds through Fresno County Superior Court.
