Gov. Maura Healey condemned the “hate-fueled” killings of two staffers of the Israeli embassy outside a charity event in Washington D.C., Wednesday night.

“I’m horrified and outraged by the murders of Yaron Lischinsky and Sarah Milgrim outside of an American Jewish Committee event in Washington D.C. last night. This was a senseless, hate-fueled act of violence,” Healey said in a statement Thursday.

The deadly attack that has stunned the nation and the international community occurred as the couple were leaving an event at the Capital Jewish Museum when the suspect, who had been seen pacing outside the museum, approached a group of four people and opened fire, Metropolitan Police Chief Pamela Smith said at a news conference.

The gunman has been identified by police as Elias Rodriguez, 31, of Chicago. Following the deadly gunfire on the street, he walked into the museum and was detained by event security and began chanting, “Free, free Palestine,” Smith said.

Lischinsky, an Israeli citizen, and Milgrim, an American, were a young couple about to be engaged, according to Yechiel Leiter, the Israeli ambassador to the U.S.

“These horrible D.C. killings, based obviously on antisemitism, must end, NOW!” President Donald Trump posted on social media early Thursday. “Hatred and Radicalism have no place in the USA.”

Healey said state local and federal authorities are in touch “to monitor new information and ensure the safety of Massachusetts communities.”

There is no known connection or direct threat to Massachusetts, Healey said.

“There is no justification for antisemitism or violence – in our nation’s capital or anywhere else, Healey continued.

“My thoughts are with Yaron and Sarah’s families, friends and colleagues, and I’m sending love and support to the Jewish community. I’m grateful to the first responders and law enforcement who responded quickly to the scene and are working in communities across the country to keep people safe.”

Israeli Prime Minister Benjamin Netanyahu’s office said on Thursday that he was shocked.

“We are witnessing the terrible price of antisemitism and wild incitement against Israel,” he said in a statement.

The U.S. Attorney’s Office in Washington, led by former judge Jeanine Pirro, will prosecute the case. Pirro and Attorney General Pam Bondi were both also at the event at the museum.

It was not immediately clear whether Rodriguez had an attorney who could comment on his behalf. A telephone number listed in public records rang unanswered.

FBI Deputy Director Dan Bongino wrote in a post on social media that “early indicators are that this is an act of targeted violence.”

Members of Massachusetts’ congressional delegation also reacted with horror to the hate attack.

“Antisemitic terrorism has no place in the world. Yaron Lischinsky and Sarah Milgrim had their entire lives ahead of them, and they were murdered for being Jewish,” said U.S. Rep. Seth Moulton.

“This is why so many American Jews and Jews around the world live in fear with the rise of antisemitism, and they deserve our help and protection like all persecuted people.”

“I am horrified by the senseless act of violence that took place outside the Capital Jewish Museum,” said U.S. Rep. Richard Neal.

“This type of hate can never be justified and cannot be tolerated. Antisemitism has no place in our country.”
