On the morning of Saturday, October 27, 2018, Robert Bowers, a 46-year-old truck driver from the suburb of Baldwin, entered a synagogue building in the Squirrel Hill neighborhood of Pittsburgh during Sabbath services and killed 11 worshippers. Three congregations shared the building, Tree of Life, Dor Hadash and New Light, and the dead came from among their members. Two other worshippers and five police officers who answered the call were wounded. Prosecutors would later describe it as the deadliest attack on Jews in the history of the United States, and federal agents built the case around one charge that no ordinary murder indictment carries: that he had set out to stop Jews from practicing their faith.
He was taken into custody the same morning and charged in federal court before the day was over. The case then took almost five years to reach a jury. In June 2023 a federal jury in Pittsburgh convicted him on all 63 counts of a superseding indictment, among them 11 counts of obstruction of free exercise of religious beliefs resulting in death and 11 counts of hate crimes resulting in death. The same jury found him eligible for the death penalty in July and voted unanimously for death on August 2, 2023. The trial judge imposed the sentence the next day. It was the first federal death sentence handed down during the presidency of Joe Biden.
His lawyers never disputed that he was the man responsible. Their fight from the first day of trial was over his life, and it moved on to the U.S. Court of Appeals for the Third Circuit, where a team of federal public defenders filed a brief of nearly 500 pages in December 2025 asking for a new sentencing hearing. At the end of 2025 he was held on federal death row in Indiana.
Bowers lived in Baldwin and worked as a truck driver. He was 46 when he was charged and 50 when the jury decided his sentence.
In the penalty phase his lawyers told the jury that his trouble began in childhood. They described a depressed and neglected boy, recounted a series of psychiatric hospitalizations, and told jurors about an extended stay in a residential mental health program for juveniles. They argued that he had schizophrenia, epilepsy and abnormalities of the brain, and that a delusional belief about Jews and immigration had driven him to the synagogue. The government answered that he held jobs, paid his bills and functioned as an adult, and that he had not been psychotic at all but had chosen to adopt white supremacist beliefs.
What the prosecution did place before the jury was a long record of his online life. In the months before the attack he posted, shared and endorsed antisemitic and white supremacist material on a social media platform, and he used it to signal what he intended to do shortly before he did it. Prosecutors told the jury that he spent six months planning the attack.
The 11 people killed that morning were members of the three congregations, many of them fixtures at services for decades. The jury heard each of their names read aloud in court.
Joyce Fienberg lived in the Oakland neighborhood of Pittsburgh. She had grown up in Toronto, at Holy Blossom Temple, and after she moved to Pittsburgh she joined Tree of Life. Richard Gottfried lived in Ross Township, and prosecutors told the jury that he was devoted to his faith. Rose Mallinger, of Squirrel Hill, was a regular at services and a devoted member of Tree of Life; people who knew her said she was full of energy.
Jerry Rabinowitz lived in the borough of Edgewood, and people across the city called him one of the kindest people in the community. Cecil Rosenthal of Squirrel Hill had attended Tree of Life services every Saturday since he was a boy, and he greeted the people who came through the doors and walked worshippers to their seats. David Rosenthal, also of Squirrel Hill, attended the same Saturday services and carried the Torah during ceremonies.
Bernice Simon and Sylvan Simon lived in Wilkinsburg, and neighbors remembered them as kind and generous to everyone. Daniel Stein lived in Squirrel Hill, and friends described him as a kind man. Melvin Wax, also of Squirrel Hill, was a member of New Light, the congregation that rented space on the lower level of the building, and a fixture at its services. Irving Younger lived in the Mount Washington neighborhood of Pittsburgh and was remembered as a man of strong faith.
The two surviving worshippers who were wounded were also members of the congregations. Five police officers who answered the call were wounded before he was taken into custody.
He was arrested in Pittsburgh the same morning. Federal prosecutors filed charges on October 27, the day of the killings, and on Monday, October 29, he made his initial appearance in federal court in Pittsburgh.
On Wednesday, October 31, 2018, a federal grand jury returned a 44-count indictment. Among its counts were 11 of obstruction of free exercise of religious beliefs resulting in death, one for each of the dead, and those counts carried a possible sentence of death.
On January 29, 2019, the U.S. Attorney's Office for the Western District of Pennsylvania announced a 63-count superseding indictment. The new document added 13 counts under the Matthew Shepard and James Byrd, Jr. Hate Crimes Prevention Act, each charging that he had willfully caused bodily injury to victims because of their actual and perceived religion, together with corresponding counts of a further offense tied to those crimes of violence.
As finally framed, the case against him consisted of 11 counts of obstruction of free exercise of religious beliefs resulting in death; 11 counts of hate crimes resulting in death; two counts of obstruction involving an attempt to kill, resulting in bodily injury, and two counts of hate crimes involving an attempt to kill, covering the surviving worshippers; eight counts of obstruction involving an attempt to kill, resulting in bodily injury to public safety officers, and four further counts of obstruction resulting in bodily injury to public safety officers; and 25 counts of a further offense tied to the crimes of violence. Twenty-two of the 63 counts, the two death counts for each of the 11 victims, carried the possibility of a death sentence. The case was docketed in the U.S. District Court for the Western District of Pennsylvania as Criminal No. 18-292.
The government later gave formal notice that it would seek death. Before trial his lawyers offered a plea of guilty in return for a sentence of life in prison. The government refused and took the case to a jury.
Jury selection began on April 24, 2023, in the federal courthouse in downtown Pittsburgh, four and a half years after the killings. The jury that was seated, seven women and five men, heard opening statements on May 30.
His defense was led by a lawyer who specialized in capital cases. From the outset the defense conceded that he had carried out the attack. Its lawyers called no witnesses and presented no evidence at the guilt stage. Their only real argument went to the element that made the obstruction counts capital crimes: they contended that his purpose had been tied to a belief about immigrants and refugees rather than to stopping anyone from worshipping, and that the charge therefore did not fit. They did not contest the hate crime counts.
The prosecution spent about 11 days putting on its case. Survivors, first responders and investigators testified, and the jury saw photographs and heard recordings from that morning. Prosecutors asked each surviving worshipper a version of the same question, whether the defendant had stopped them from praying. Eight people who were in the building that morning came through it without physical injury.
The jury deliberated for about five hours over two days. At one point it asked the court to clarify what was required for the counts charging an attempt to kill eight of the survivors, counts 40 through 47, and the judge referred the jurors back to his written instructions. On Friday, June 16, 2023, at about noon, the verdicts were read: guilty on all 63 counts. Polled one by one, every juror affirmed every verdict. The 63 convictions comprised 22 capital offenses and 41 other charges.
Federal law divides a capital case into stages, and in his trial the judge separated them. The penalty phase opened on Monday, June 26, 2023, with the first question alone: whether he was legally eligible for death at all. The court had set aside about six weeks for the whole of the penalty phase.
The defense put its mental-health case at this stage, arguing that schizophrenia, epilepsy and brain abnormalities had left him unable to form the intent the law requires. The government answered that he had plotted the attack carefully and denied that mental illness played any part. On July 13, 2023, after deliberating for less than two hours, the jury found that he had formed the required intent to kill and that he was eligible for a sentence of death.
The final stage turned on whether he should die or spend the rest of his life in prison. Prosecutors relied on the vulnerability of the victims, on his careful planning, and on religious hatred as his motive. Survivors testified about what the killings had taken from them. The defense returned to his childhood and his psychiatric history and asked the jury to weigh them.
Closing arguments came on July 31. The government asked for death on the ground that religious hatred had driven the killings; the defense asked for life, pressing the jurors to give weight to his childhood and his psychiatric history.
On Wednesday, August 2, 2023, the jury returned its verdict. It found aggravating factors, among them that he had been motivated by hatred of Jews, that he had chosen the building to maximize the devastation, and that he lacked remorse. It accepted that his difficult childhood deserved consideration, but rejected most of the defense's central claims for a life sentence, including that he had schizophrenia and that delusions about Jews had driven him. Unanimously, it found that the aggravating factors outweighed the mitigating ones and voted for death.
The formal sentencing took place on Thursday, August 3, 2023. Survivors addressed the court. He chose not to speak. He spent the hearing looking through papers and writing, and did not look at the people who spoke, even when they asked him to. The presiding U.S. district judge sentenced him to death on the 22 capital counts of the superseding indictment.
In late August 2023 he was moved to the federal death row in Indiana, the only place where federal executions are carried out. No execution date was set. Thirteen federal prisoners had been executed there in 2020 and 2021. At the time the Justice Department was observing a moratorium on federal executions, imposed by the Attorney General while the department reviewed its capital policies.
In the fall of 2023 his lawyers filed post-trial motions, about 40 pages long, asking the district court to enter a judgment of acquittal or to grant a new trial. They argued that prosecutors had excluded prospective jurors who were Black, Hispanic and Jewish, and that the evidence had not proved that his hatred was directed at the victims because they were religious or were engaged in religious practice.
The trial judge rejected the motions in a 26-page ruling released on May 17, 2024. He held that the jury had ample evidence to find that the victims had been targeted because of their religion and called the contrary argument baseless. The defense had also raised the constitutionality of the federal hate crime charges; the judge acknowledged that the issue would likely surface on appeal, but dismissed it because no argument had actually been made in support of it. The ruling cleared the way for the appeal to the Third Circuit.
On December 23, 2024, weeks before leaving office, President Biden commuted the sentences of 37 of the 40 people on federal death row to life without the possibility of parole. He was one of the three left out. The White House said the president believed the federal death penalty should end except in cases of terrorism and hate-motivated mass murder, and his sentence of death was left in place.
In December 2025, almost two and a half years after the sentence, his federal public defenders filed their opening brief in the U.S. Court of Appeals for the Third Circuit. The brief runs close to 500 pages and raises 16 issues. It does not ask the court to overturn the convictions; it asks, at the least, for a new sentencing hearing, and it accuses the government and the trial court of overreach, arguing that the trial was compromised by constitutional and statutory failures in charging, jury selection and sentencing procedure.
Several of the claims concern the jury. The brief argues that prosecutors improperly struck prospective jurors who were Black, Hispanic or Jewish, and that the defense was not given enough time to make that argument during selection. It argues that the government struck jurors who opposed the death penalty but said they could follow the law. It challenges the seating of Juror 119, who had reviewed death sentences and supervised executions in China, on the ground that the court asked only whether she could apply American law and never examined her for bias.
Another claim concerns restraints. Beginning in early July 2023, during the trial, the judge allowed his legs to be shackled at the defense table on the strength of security concerns raised by the U.S. Marshals Service. The brief argues that the restraints harmed his ability to take part in his own trial, that the defense's objections were dismissed, and that his lawyers did not receive a full explanation of the marshals' concerns until months after the trial was over. His lawyers also told the appeals court that they had needed time to work through five years of pretrial litigation and three months of trial testimony. The government had 90 days to respond.
As of the end of December 2025, he remained on federal death row in Indiana while the appeal went forward.
His guilt was never in dispute at trial; the defense conceded it in its opening statement. What remained contested was his mental state. The defense maintained that he suffered from schizophrenia and other serious disorders and that delusion, not settled hatred, explained the attack. The government disputed the diagnosis, and the jury rejected the schizophrenia claim when it chose death.
The defense also disputed, without success, that his purpose met the legal definition of obstructing religious exercise, arguing that his target was the congregations' work with refugees rather than their worship. The trial judge held the evidence sufficient, and the point is among the issues the Third Circuit has been asked to consider alongside the jury-selection and shackling claims. Until that court rules, the death sentence is not final.
