Black, 71, recalled how she remained hidden even as she saw congregant Mel Wax, who had been hiding close to her, drop dead after the gunman shot him. Wax, 87, was hard of hearing and had opened the storage door, apparently believing the attack was over, she said. Black didn’t learn until later that her 65-year-old brother, Richard Gottfried, was among the 11 people killed in the attack.

The testimony came in the trial of Robert Bowers, a truck driver from the Pittsburgh suburb of Baldwin. Bowers, 50, could face the death penalty if he’s convicted of some of the 63 counts he faces in the Oct. 27, 2018, attack, which claimed the lives of worshippers from three congregations who were using the synagogue that day: New Light, Dor Hadash and the Tree of Life.

That Bowers carried out the attack, which also injured seven people, isn’t in question: His lawyer Judy Clarke acknowledged as much on the trial’s first day. But hoping to spare Bowers from the death penalty, Clarke questioned the hate crime counts he faces, suggesting instead that he attacked the synagogue out of an irrational belief that he needed to kill Jews to save others from a genocide that he claimed they were enabling by helping immigrants come to the U.S.

Prosecutors, who rejected Bowers’ offer to plead guilty in exchange for removing the possibility that he could be sentenced to death, have said Bowers made incriminating statements to investigators and left an online trail of antisemitic statements that shows the attack was motivated by religious hatred.

Bowers, who only surrendered on the day of the attack after police shot him three times, had commented on Gab, a social media site popular with the far right, that Dor Hadash had hosted a refugee-oriented Sabbath service in conjunction with HIAS, a Jewish agency whose work includes aiding refugees.

Assistant U.S. Attorney Soo Song began Wednesday’s proceedings by asking Black about her affiliation with the New Light congregation. She recalled how her brother, Gottfried, became more observant after their father’s death and how she later began attending services regularly, getting so involved that she had an adult bat mitzvah — a Jewish right of passage that she hadn’t had as a teenager.

“I was rededicating myself to Judaism,” she said.

She recalled fondly how in 2017, she and her brother carried Torah scrolls as they paraded from their old synagogue, which the small congregation had sold in a downsizing, to their new location in rented space at the Tree of Life building.

She said Gottfried, Wax and 71-year-old Dan Stein were “the three main pillars of our congregation.” On the morning of the attack, Gottfried and Stein were in a kitchen near the sanctuary planning a men’s group breakfast for the next day when Bowers killed them.

Black said she and fellow member Barry Werber hid in a darkened storage closet for what “felt like a year” before police rescued them. And she said that as she left, she quietly said goodbye to Wax as she had to step over his body to follow the officers.

Werber, 81, also testified about hiding in the closet.

“My mind was clouded with panic,” said Werber, who also saw Wax get killed.

“I heard gunshots,” Werber testified. “Mel Wax fell back into the room, and a short time later the door opened slightly. I saw a figure of a person step over the body and then step back. He couldn’t see us. It was too dark.”

Jurors also heard the recordings of 911 calls made by Werber and Gottfried.

Bowers, like on the trial’s first day, showed little emotion as he sat at the defense table.

Jurors also heard testimony from Dan Leger, who was severely wounded in the attack.

Leger, now 75, and two other members of Dor Hadash were gathered in an upstairs room about to start a Torah study when they heard gunshots. One of the participants fled. Leger, a nurse and chaplain, and Dr. Jerry Rabinowitz decided to see if they could assist anyone who might be injured.

“Jerry was a physician, I’m a nurse. ... We knew instinctively that what we needed to do was try to do something to help. So we both moved into the direction of the gunfire, which perhaps was a stupid thing to do, but that’s what we did,” Leger said.

Rabinowitz, 66, was killed. Leger was shot in the abdomen and lay on the staircase, keeping still so as not to let the shooter know he was still alive.

He heard the voice of Tree of Life member Irving Younger calling out the name of fellow member Cecil Rosenthal in horror. Younger and Rosenthal were both killed.

The pain soon became “excruciating,” Leger said.

While waiting for rescue, Leger said his breathing became labored, and he recognized the symptoms: “I felt that I was dying.”

He uttered the Shema — a Jewish prayer professing faith in one God — and he prayed a final confession of his sins.

“I reviewed my life, I thought about the wonder of it all, and the beauty of my life and the happiness I had experienced,” he said, including with his family and friends.

Although he said he was “ready to go,” Leger was rescued and underwent multiple surgeries. He still suffers from severe injuries, including a hip fracture, nerve damage and abdominal wounds that required the removal of a large section of his intestines.
