Police have arrested a suspect in the shooting of three young men of Palestinian descent who were attending a Thanksgiving holiday gathering near the University of Vermont campus Saturday evening.

Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives arrested Jason J Eaton, 48, while conducting a search of the shooting area in Burlington at 3:38 pm Sunday, the Burlington Police Department said in a statement.

Authorities collected evidence during a search of Eaton’s apartment in a building in front of the shooting location. He is scheduled to be arraigned Monday, police said.

The attack that injured the three men around 6:25 pm Saturday may have been a hate crime, authorities previously said.

Two of the men were in stable condition and the other suffered “much more serious injuries,” Burlington Police Chief Jon Murad said in a statement Sunday. The three, all age 20, were walking during a visit to the home of one of the victim’s relatives when they were confronted by a white man with a handgun, police said.

“Without speaking, he discharged at least four rounds from the pistol and is believed to have fled,” Murad said. “All three victims were struck, two in their torsos and one in the lower extremities.”

The victims are all of Palestinian descent. Two are US citizens and the third is a legal resident. Two of the men were wearing the black-and-white Palestinian keffiyeh scarves, Murad said.

Burlington Mayor Miro Weinberger is expected to join Murad at a press conference Monday to discuss the investigation.

Murad, who expressed sympathies for the victims and their families, said there is no additional information to suggest a motive.

“In this charged moment, no one can look at this incident and not suspect that it may have been a hate-motivated crime. And I have already been in touch with federal investigatory and prosecutorial partners to prepare for that if it’s proven,” he said.

“The fact is that we don’t yet know as much as we want to right now,” Murad added. “But I urge the public to avoid making conclusions based on statements from uninvolved parties who know even less.”

The American-Arab Anti-Discrimination Committee released a statement Sunday saying that the victims were Palestinian American college students and that there is “reason to believe this shooting occurred because the victims are Arab.”

A man shouted and harassed the victims, who were conversing in Arabic, then proceeded to shoot them, the committee’s statement said.

The FBI in Albany, New York, posted a statement late Sunday on X, formerly Twitter, saying the bureau is actively investigating the shooting with the Burlington Police Department, the ATF and other federal, state and local agencies.

The White House said President Joe Biden was briefed on the shooting and would continue to receive law enforcement updates.

The Council on American-Islamic Relations released a statement offering a $10,000 reward for information leading to an arrest or conviction of the person or people responsible for the shootings.

The Institute for Middle East Understanding posted a statement on X that the institute said was from the victims’ families.

“We are extremely concerned about the safety and well-being of our children,” the statement said. “We call on law enforcement to conduct a thorough investigation, including treating this as a hate crime. We will not be comfortable until the shooter is brought to justice.”

Ramallah Friends School posted a statement on Facebook saying the three young men were graduates of the private school in the West Bank.

“While we are relieved to know that they are alive, we remain uncertain about their condition and hold them in the light,” the school said. “We stand united in hope and support for their well-being during this challenging time.”

In response to the shooting, US House Minority Leader Hakeem Jeffries encouraged people to “unequivocally denounce the startling rise of anti-Arab hate and Islamophobia in America.”

“No one should ever be targetted for their ethnicity or religious affiliation in our country,” the New York Democrat said in the statement posted on X. “We will not let hatred win.”

Senator Bernie Sanders, the Vermont Independent, also denounced the shooting.

“It is shocking and deeply upsetting that three young Palestinians were shot here in Burlington, VT. Hate has no place here, or anywhere. I look forward to a full investigation,” Sanders said in a statement.

Governor Phil Scott called the shooting a tragedy, calling on the state’s residents to unite and “not let this incident incite more hate or divisiveness.”

The Vermont-New Hampshire chapter of Jewish Voice For Peace, which has urged an end to the Israel-Hamas war, released a statement saying it was “appalled by the shooting.”

“We are in solidarity with the students, their families and all those affected by this clear act of hate,” the organisation said Sunday. “We are in solidarity with all Palestinian people in occupied Palestine, around the world, and here in Vermont — and we are committed to creating a Vermont that is safe and welcoming for all.”

The American Jewish Committee, an advocacy organisation for Jewish people worldwide, also said via X it was “horrified” by the attack and urged “law enforcement to investigate this act as a possible hate crime.”

Last month, an Illinois landlord was charged with a hate crime after being accused of fatally stabbing a 6-year-old Muslim boy and seriously wounding his mother in Chicago. Police and relatives said he singled out the victims because of their faith.

Demonstrations have been widespread and tensions in the US have escalated as the death toll rises in the Israel-Hamas war. A fragile cease-fire between Israel and Hamas was back on track Sunday as the militants freed more hostages and Israel released 39 Palestinian prisoners. It was the third exchange under a four-day truce deal.
