The 11 Jews massacred on Saturday by a white supremacist gunman at the Tree of Life synagogue in Pittsburgh have been identified.

The victims included:

– Joyce Fienberg, 75, of Oakland, City of Pittsburgh

– Richard Gottfried, 65, of Ross Township

– Rose Mallinger, 97, of Squirrel Hill, City of Pittsburgh

– Jerry Rabinowitz, 66, of Edgewood Borough

– Cecil Rosenthal, 59, of Squirrel Hill, City of Pittsburgh

– David Rosenthal, 54, (brother of Cecil), of Squirrel Hill

– Bernice Simon, 84, of Wilkinsburg

– Sylvan Simon, 86, (husband of Bernice), of Wilkinsburg

– Daniel Stein, 71, of Squirrel Hill, City of Pittsburgh

– Melvin Wax, 88, of Squirrel Hill, City of Pittsburgh

– Irving Younger, 69, of Mount Washington, City of Pittsburgh

Six other people — among them four police officers — were wounded in the attack.

Officials said on Sunday that the suspected perpetrator – 46-year-old Robert Bowers — likely acted alone.

Bowers, who was arrested at the scene of the attack, will make an initial appearance before a judge on Monday afternoon.

During the rampage, Bowers made statements about genocide and his desire to kill Jewish people, officials said.

The mass shooting prompted security alerts at houses of worship around the country and condemnation from politicians and religious leaders.

“We’ll get through this darkest day of Pittsburgh history by working together,” the city’s mayor, Bill Peduto, told reporters on Sunday.

Bowers had made many antisemitic posts online, including one early on Saturday.

The final post said a Jewish refugee organization, the Hebrew Immigrant Aid Society (HIAS), “likes to bring invaders in that kill our people. I can’t sit by and watch my people get slaughtered. Screw your optics, I’m going in.”

Bowers surrendered after a shootout with a SWAT team. Federal prosecutors charged him late on Saturday with 29 criminal counts including violence and firearms offenses, and violating US civil rights laws.

The Anti-Defamation League and Jewish Council for Public Affairs described Saturday’s incident as the deadliest attack on the Jewish community in the history of the United States.

KDKA television cited police sources as saying Bowers walked into the building and yelled, “All Jews must die.”

FBI Special Agent Robert Jones said Bowers was armed with an assault rifle and three handguns.

He said authorities believed the suspect entered the synagogue, murdered the worshippers and was leaving when he encountered a uniformed police officer. The pair exchanged gunfire, Jones said, and Bowers reentered the building before a SWAT team arrived.

Bowers was taken to a hospital where he was listed in fair condition with multiple gunshot wounds.
