Pennsylvania authorities have named the eight men and three women who were killed at a synagogue on Saturday.
Suspect Robert Bowers, 46, is in custody and faces 29 criminal counts for what is thought to be the worst anti-Semitic attack in recent US history.
Allegheny County chief medical examiner Dr Karl Williams said two brothers and a husband and wife are among the dead.
The victims ranged in age from 54 to 97 years old.
Who are the victims?
Dr Williams named the 11 at a press conference on Sunday:
- Joyce Fienberg, 75
- Richard Gottfried, 65
- Rose Mallinger, 97
- Jerry Rabinowitz, 66
- Cecil Rosenthal, 59
- David Rosenthal, 54, brother of Cecil
- Bernice Simon, 84
- Sylvan Simon, 86, husband of Bernice
- Daniel Stein, 71
- Melvin Wax, 88
- Irving Younger, 69
Ms Fienberg was the widow of Stephen Fienberg, a statistics professor at Carnegie Mellon University.
According to his obituary on the university’s website, Professor Fienberg died in 2016 and his funeral service was held at the Tree of Life synagogue that December.
He and his wife had two sons, Anthony and Howard, and six grandchildren.
Ms Fienberg reportedly lived in Oakland, a district west of the university where her husband worked.
Dr Rabinowitz ran a family medical practice in Bloomfield, a short drive north-west from the Tree of Life synagogue.
An article written by a patient, Ben Schmitt, has appeared on the Pittsburgh Tribune website, praising Dr Rabinowitz for his kindness and his care.
“Kind and funny, Dr. Rabinowitz completely personified the term ‘bedside manner’,” the article reads.
Other patients also took to social media to tell stories about their doctor.
Cecil and David Rosenthal
The brothers, 59 and 54 respectively, were both reportedly from Squirrel Hill.
According to the Washington Post, both had learning disabilities and had been attending the synagogue since they were young children.
Cecil and David served as honorary chairs when Tree of Life held special services for adults with disabilities, the piece says.
Tributes have appeared on Twitter to the siblings.
Bernice and Sylvan Simon
The married couple reportedly lived in Wilkinsburg, a Pittsburgh district east of the synagogue.
According to a Pittsburgh Tribune article, Mr Stein served as president of the New Light Congregation, a conservative Jewish synagogue in Squirrel Hill which holds services at the Tree of Life.
“He was very active and he did everything,” nephew Steven Halle told the paper. “He was there every Saturday for services.”
Mr Stein was reportedly a new grandfather.
Mr Wax was also reportedly an active and well-known New Light congregant.
A friend, Myron Snider, described the retired accountant as a “sweet, sweet guy” and unfailingly generous.
“When my daughters were younger, they would go to him, and he would help them with their federal income tax every year,” Mr Snider was quoted by the Associated Press as saying. “Never charged them.”
