COLLEYVILLE, Texas — A rabbi who was among four people held hostage at a Texas synagogue said Sunday that their armed captor grew “increasingly belligerent and threatening” toward the end of the 10-hour standoff, which ended with an FBI SWAT team rushing into the building and the captor’s death.
Authorities identified the hostage-taker as a 44-year-old British national, Malik Faisal Akram, who was killed Saturday night after the last hostages ran out of Congregation Beth Israel around 9 p.m. The FBI said there was no indication that anyone else was involved, but it had not provided a possible motive as of Sunday afternoon.
Rabbi Charlie Cytron-Walker credited security training that his suburban Fort Worth congregation has received over the years for getting him and the other three hostages through the ordeal, which he described as traumatic.
“In the last hour of our hostage crisis, the gunman became increasingly belligerent and threatening,” Cytron-Walker said in a statement. “Without the instruction we received, we would not have been prepared to act and flee when the situation presented itself."
President Biden called the episode an act of terror. Akram could be heard ranting on a Facebook livestream of the services and demanding the release of Aafia Siddiqui, a Boston-educated Pakistani neuroscientist suspected of having ties to Al Qaeda who was convicted of trying to kill US Army officers in Afghanistan.
Siddiqui graduated from the Massachusetts Institute of Technology in 1995 and earned a doctorate from Brandeis University in 2001. At MIT, she was known to classmates as a studious, pious woman who was devoted to Islam and part of a group of Muslim students and the school’s Muslim Student Association.
Speaking to reporters in Philadelphia on Sunday, Biden said Akram allegedly purchased a weapon on the streets.
Federal investigators believe Akram purchased the handgun used in the hostage-taking in a private sale, according to a person familiar with the matter who spoke on condition of anonymity because the investigation is ongoing. Akram arrived in the United States at John F. Kennedy International Airport in New York about two weeks ago, a law enforcement official said.
Video from Dallas TV station WFAA showed people running out a door of the synagogue, and then a man holding a gun opening the same door just seconds later before he turned around and closed it. Moments later, several shots and then an explosion could be heard.
“Rest assured, we are focused,” Biden said. “The attorney general is focused and making sure that we deal with these kinds of acts.”
Akram arrived on a tourist visa from Great Britain, according to a US official who spoke on the condition of anonymity because the information was not intended to be public. London’s Metropolitan Police said in a statement that its counter-terrorism police were liaising with US authorities about the incident.
FBI Special Agent in Charge Matt DeSarno said the hostage-taker was specifically focused on an issue not directly connected to the Jewish community. It wasn’t clear why Akram chose the synagogue, though the prison where Siddiqui is serving her sentence is in Fort Worth.
Michael Finfer, the president of the congregation, said in a statement “there was a one in a million chance that the gunman picked our congregation.”
Authorities have declined to say who shot Akram, saying it was still under investigation.
Authorities said police were first called to the synagogue around 11 a.m., and people were evacuated from the surrounding neighborhood soon afterward.
Saturday's services were being livestreamed on the synagogue's Facebook page for a time. The Fort Worth Star-Telegram reported that an angry man could be heard ranting and talking about religion at times during the livestream, which didn't show what was happening inside the synagogue.
Shortly before 2 p.m., the man said, “You got to do something. I don’t want to see this guy dead.” Moments later, the feed cut out. A spokesperson for Meta Platforms Inc., the corporate successor to Facebook Inc., later confirmed that Facebook had removed the video.
Akram used his phone during the course of negotiations to communicate with people other than law enforcement, according to a law enforcement official who was not authorized to discuss an ongoing investigation by name and spoke on condition of anonymity.
Multiple people heard the hostage-taker refer to Siddiqui as his “sister” on the livestream. But John Floyd, board chair for the Houston chapter of the Council on American-Islamic Relations — the nation’s largest Muslim advocacy group — said Siddiqui’s brother, Mohammad Siddiqui, was not involved.
“We want the assailant to know that his actions are wicked and directly undermine those of us who are seeking justice for Dr. Aafia,” said Floyd, who also is legal counsel for Mohammad Siddiqui.
Reached outside his home Sunday, Cytron-Walker declined to speak at length about the episode. “It’s a little overwhelming as you can imagine. It was not fun yesterday,” he told the AP.
Cytron-Walker spent time working at a Massachusetts food pantry about two decades ago. The Lansing, Mich., native graduated from the University of Michigan in 1998, according to an online biography. Following graduation, he worked at a human rights organization in Detroit and then became the assistant director of the Amherst Survival Center, which operates a food pantry and other services.
The Amherst organization, in a Facebook message posted during the standoff Saturday, identified Cytron-Walker as a former staff member.
Andrew Marc Paley, a Dallas rabbi who was called to the scene to help families and hostages upon their release, said Cytron-Walker acted as a calm and comforting presence. The first hostage was released shortly after 5 p.m. That was around the time food was delivered to those inside the synagogue, but Paley said he did not know if it was part of the negotiations.
“He appeared a little unfazed, actually, but I don't know if that was sort of shock or just the moment," Paley said of the first hostage who was released.
Cytron-Walker said his congregation had received training from local authorities and the Secure Community Network, which was founded in 2004 by a coalition of Jewish organizations and describes itself as “the official safety and security organization” of the Jewish community in North America. Michael Masters, the CEO of the organization, said the congregation had provided security training in August and had not been previously aware of Akram.
