Deputies say Daniel Antonio Perez opened fire without known provocation before fleeing, calling 911 and hiding several blocks from the shooting.

SAN ANTONIO, Texas — A 40-year-old man faces two capital murder charges after authorities said he crossed a residential street and opened fire on two brothers outside their family’s home, killing an 11-year-old boy and his 20-year-old brother in an attack investigators have described as unprovoked.

Daniel Antonio Perez is accused in the Aug. 4 deaths of Maliki Perales, 11, and Drayvn Quiroz, 20, who were near a family vehicle at their home in the 9800 block of Acadian Drive on the far West Side of the San Antonio area. Bexar County Sheriff Javier Salazar said investigators had found no known dispute between Perez and the victims before the shooting. Perez, who lived across the street, was arrested nearby after deputies tracked his cellphone signal, authorities said. Court records cited by local news outlets show he is being held on bonds totaling $2.3 million.

The case escalated from a neighborhood shooting investigation into a double capital murder case as both brothers died from their injuries. The shooting happened at about 7:30 p.m., according to the Bexar County Sheriff’s Office. Authorities said the brothers were moving the family vehicle in the driveway when Perez came from the other side of the street and began shooting. Both were critically wounded and taken for emergency medical care. Maliki died later that evening. Quiroz remained hospitalized overnight but died the next morning, shortly before Salazar gave a news conference about the case.

Investigators say the danger did not end with the gunfire directed at the two brothers. Salazar said a 14-year-old boy and a 17-year-old girl, also members of the family, were near the front of the home when Perez allegedly fired toward them. Neither teenager was struck. The additional alleged gunfire became part of a group of aggravated assault charges filed against Perez. KSAT reported that court records list two counts of capital murder, one count of aggravated assault causing serious bodily injury and four counts of aggravated assault with a deadly weapon. The charges are allegations, and the case has not been adjudicated.

The younger victim’s death was formally ruled a homicide, according to information from the Bexar County Medical Examiner’s Office reported by KSAT. The office identified Maliki and Quiroz after the shooting. Maliki suffered fatal gunshot wounds, while the cause and manner of Quiroz’s death were still pending in the medical examiner information available immediately after the attack. The deaths turned what had begun as a rapid emergency response on Acadian Drive into a homicide investigation involving multiple victims, neighborhood video, physical evidence and accounts from relatives and witnesses.

Authorities said Perez ran from the area after the shooting while still armed. During the search, he called 911 and told a dispatcher that he had shot his neighbors, Salazar said, but did not provide officers with his location. Deputies instead used information from his cellphone to narrow the search. They located him roughly a quarter-mile from the scene, where authorities said he was hiding in the backyard of a home that did not belong to him. Deputies confronted him and took him into custody at gunpoint without a further exchange of gunfire. The arrest came about 10 minutes after the shooting, according to accounts of the sheriff’s briefing.

Investigators also recovered a handgun from a drainage culvert several houses away, Salazar said. Nearby doorbell-camera footage became another part of the investigation. According to KSAT, video showed Perez knocking at another home and making statements suggesting that he believed he was in danger. Salazar said investigators had not found evidence showing that the brothers had threatened Perez or otherwise provoked the gunfire. The sheriff characterized the shooting as an attack for which the victims had no warning, while making clear that detectives were continuing to examine Perez’s conduct and statements before and after the shots were fired.

Questions about Perez’s mental condition emerged after investigators spoke with members of his family. Salazar said relatives described past periods of depression and episodes in which Perez appeared to see things that were not there. Authorities said they were not aware of a previous law enforcement report concerning those episodes, and investigators said Perez did not appear to have a prior criminal record. The sheriff described the situation as involving an apparent mental health crisis but stopped short of treating that as an explanation that resolved the criminal investigation. No independent medical diagnosis establishing Perez’s condition at the time of the shooting has been publicly released in the reports reviewed for this story.

Salazar pointed to Perez’s alleged actions after the shooting as significant to the investigation. Authorities say Perez left the scene, discarded the handgun and concealed himself in a backyard while deputies searched for him. The sheriff said those actions showed that Perez retained the ability to take deliberate steps after the gunfire. “While clearly there’s some sort of a mental health crisis going on, he still had the presence of mind and the culpable mental state to go conceal the weapon somewhere and then go conceal himself somewhere else,” Salazar said. Whether any mental health evidence becomes part of Perez’s legal defense will be a matter for the court and has not been established by the public reporting.

The shooting left the Perales family mourning two sons while two other siblings survived what authorities say was additional gunfire directed toward the house. Their father, Andrew Perales, told News 4 San Antonio that the family had no enemies and was known for helping people. He described his sons as close to the family and recalled spending time working, barbecuing and watching movies with them. He said Quiroz had worked alongside him in the family business. Salazar also described the family as generous toward neighbors, telling reporters that they were known for feeding people in the community. Those accounts added a picture of the victims beyond the circumstances of their deaths.

Family members also described what had been an ordinary evening before the violence. Andrew Perales told local media that the family had asked for the vehicle to be adjusted in the driveway because of concern that it was blocking the sidewalk. He said he was ordering food when the gunfire began. The account helps explain why investigators have repeatedly emphasized the absence of a known confrontation leading up to the shooting. Authorities have not publicly identified a dispute between the families or announced a verified motive. Perez’s apparent statements suggesting fear or self-defense remain part of the evidence being examined, but Salazar said investigators had found nothing supporting the idea that the victims initiated an attack.

The legal process remains in its early stages. Court information reported by KSAT and Telemundo listed Perez’s next appearance for Nov. 3, 2026, with the proceeding described as a pre-indictment hearing. Prosecutors had not publicly announced in the reports reviewed whether they would ultimately seek the death penalty, and a capital murder charge does not by itself establish what punishment will be pursued. Until the case moves through indictment and later court proceedings, the sheriff’s account represents the government’s allegations rather than a finding of guilt.

For investigators, the remaining work includes completing forensic reviews, establishing a full timeline of Perez’s movements and determining whether any additional evidence sheds light on why the shooting occurred. For the victims’ family, the central facts are already irreversible: two brothers died after gunfire erupted outside the place where they lived, while two other siblings escaped being struck. Perez remained jailed on the pending charges as the case awaited its next scheduled court proceeding.
