Prosecutors said Brandon Smith turned a predawn argument inside his family’s home into a deadly attack that left his younger brother dead and their mother pleading for help.
MILWAUKEE, Wis. — A Milwaukee County jury has convicted Brandon Smith in the killing of his younger brother after prosecutors said a long night of paranoid accusations inside the family home ended in a hammer attack and a gunshot on Feb. 26, 2025.
The verdict, returned April 1, closes the trial phase of a case that drew attention because nearly every key moment happened inside one house and in front of the brothers’ mother. Smith, now 51, was found guilty of first-degree reckless homicide in the death of 41-year-old Justin Smith, a lesser conviction than the original first-degree intentional homicide charge filed after the shooting. The next major step is sentencing on June 5, when a judge will decide how much prison time Smith will serve for the killing.
According to the criminal complaint, the violence came after months of growing tension in the house on the 4900 block of North 47th Street, near 47th and Stark on Milwaukee’s northwest side. Brandon Smith had been living there since the previous September because of his divorce. Their mother told investigators she believed her older son had become more paranoid and was showing signs of mental health trouble. She said he had become convinced that Justin Smith had been in an intimate relationship with his ex-wife, even though she said that was not true. He also believed, the complaint said, that his brother was monitoring him through his cellphone and setting him up to be killed. At about 4 a.m. on Feb. 26, he accused Justin Smith of bringing another man to the house to hurt him. Their mother said Justin Smith stayed in his room and “would not engage in the argument,” but Brandon Smith was still agitated enough to call police. Officers came to the house and then left, and the argument kept going. Their mother said she had to separate the two men and send them back to their rooms, but Brandon Smith told investigators he still did not feel safe and began walking the stairs and hallways, effectively patrolling the house before sunrise.
The complaint says the mother was in the living room when Brandon Smith again started saying that people were trying to kill him. He went back upstairs, and she fell asleep. She woke to the sound of Justin Smith screaming and found the brothers fighting on the floor, with Brandon Smith on top and Justin Smith bleeding from the head. Investigators said Brandon Smith struck his younger brother twice with a hammer. Their mother rushed in, broke up the fight and got the hammer away as Justin Smith went to a bedroom. But the confrontation did not end there. Prosecutors said Brandon Smith then retrieved a handgun and shot Justin Smith in the chest. In his own statement to investigators, Brandon Smith said he believed he still had to defend himself. The complaint says he later “felt like he still needed to protect himself,” even after seeing his brother fall. Their mother tried to help Justin Smith and tried to call 911, but the complaint says Brandon Smith would not let her go at first. He went to wash up while she remained with the wounded man. When she finally got the chance to reach police, the house had become a homicide scene. Officers arrived around 6:43 a.m. and, as the mother led one officer through the home, she pointed out Brandon Smith and said, “this is the one that hurt the other one.” In a separate bedroom, officers found Justin Smith on the floor, surrounded by blood.
Investigators built the case around those statements, the physical evidence inside the home and Smith’s own account of what he thought he heard. Police recovered the hammer near the victim, and a detective wrote that it was covered in blood. Officers also recovered two firearms from the house, including the gun the mother said Brandon Smith used in the shooting and then hid in couch cushions. An autopsy later found that Justin Smith had multiple blunt-force injuries to his head and face and that his clothing was covered in blood, but his cause of death was a gunshot wound to the chest. The records described a case in which fear and suspicion, not any confirmed outside threat, drove the violence. Brandon Smith told investigators he believed his brother and another man were discussing how to ambush him outside the house, but the complaint says he admitted he never actually saw anyone else there. Their mother told detectives that no one other than the three of them had been in the home during the early-morning argument. The complaint also said Brandon Smith believed his brother’s supposed relationship with his ex-wife was part of the threat against him, though their mother rejected that claim. In another detail that underlined how the fight spiraled, Brandon Smith told police that he and his brother “had never pulled guns on each other before.”
The legal path in the case moved from a charge of first-degree intentional homicide to a jury conviction for first-degree reckless homicide, reflecting the offense jurors found the evidence proved beyond the higher original count. After the killing, Smith made his initial court appearance on March 2, 2025, and a judge set cash bond at $150,000. A preliminary hearing was scheduled for March 12 as the case moved through Milwaukee County court. By the time jurors heard the case this spring, prosecutors were arguing that Smith’s conduct inside the house showed extreme danger and disregard for human life, even if the final verdict did not match the original intent-based accusation. Under Wisconsin law, first-degree reckless homicide is a Class B felony, one of the state’s most serious criminal offenses, carrying a maximum prison term of 60 years. That means the June 5 sentencing hearing will be the next critical stage for both sides. The court is expected to hear arguments about punishment, and it may also hear victim impact statements and any sentencing recommendation from the defense. Public reporting on the verdict has not laid out the full sentencing positions yet, but the conviction ensures Smith now faces a lengthy prison exposure in a case that began with one family argument and ended in a brother’s death.
What stayed with investigators, and now defines the public record of the case, was how many of the most important details came from inside the home itself. The mother appears in the complaint as the person who first tried to calm the brothers, then took the hammer away, then tried to call for help, then directed officers to the suspect when they arrived. Her account also shaped the central conflict in the case. She told detectives her older son had grown more isolated, did not have a job, rarely left the house and had begun to see threats that she said were not real. Police said Brandon Smith later ranted about the Bible, Cain and Abel, and neighbors he believed wanted him dead. That language, paired with the earlier police visit that did not stop the dispute, gave jurors a stark timeline of a family crisis deepening over a matter of hours. By the time officers returned after daybreak, Justin Smith was dead in a bedroom, Brandon Smith was still inside the house and the woman who had tried to stop the fight was left to identify one son as the man who had killed the other.
As of Friday, the conviction stands and Brandon Smith is scheduled to return to Milwaukee County court for sentencing on June 5. The next public milestone in the case will be the judge’s decision on punishment and any statements the family, prosecutors or defense lawyers make before sentence is imposed.
