WASHINGTON (AP) — On Wednesday night, two staff members from the Israeli embassy were fatally shot while exiting a function at a Jewish museum in the capital. After authorities arrested the suspect, he reportedly shouted, “Free, free Palestine,” police reported.

The victims, a man and a woman, had just left an event at the Capital Jewish Museum when the suspect approached a group of four individuals and began shooting, according to Metropolitan Police Chief Pamela Smith during a press briefing.

The suspect, Elias Rodriguez, a 30-year-old from Chicago, was seen pacing near the museum prior to the shooting. Afterward, he entered the museum where event security detained him, Smith stated.

When he was taken into custody, the suspect began chanting, “Free, free Palestine,” Smith said. Smith said law enforcement did not believe there was an ongoing threat to the community.

Israeli Ambassador to the U.S. Yechiel Leiter said the two people killed were a young couple about to be engaged, saying the man had purchased a ring this week with the intent to propose next week in Jerusalem.

Attorney General Pam Bondi said she was at the scene with former judge Jeanine Pirro, who serves as the U.S. attorney in Washington and whose office would prosecute the case.

“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. Condolences to the families of the victims. So sad that such things as this can happen! God Bless You ALL!’

Israeli President Isaac Herzog said he was “devastated” by the scenes in Washington.

“This is a despicable act of hatred, of antisemitism, which has claimed the lives of two young employees of the Israeli embassy. Our hearts are with the loved ones of those murdered and our immediate prayers are with the injured. I send my full support to the Ambassador and all the embassy staff.”

He added: “We stand with the Jewish community in DC and across the US. America and Israel will stand united in defense of our people and our shared values. Terror and hate will not break us.”

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.

Yoni Kalin and Katie Kalisher were inside the museum when they heard gunshots and a man came inside looking distressed, they said. Kalin said people came to his aid and brought him water, thinking he needed help, without realizing he was the suspect. When police arrived, he pulled out a red keffiyeh and repeatedly yelled, “Free Palestine,’” Kalin said.

“This event was about humanitarian aid,” Kalin said. “How can we actually help both the people in Gaza and the people in Israel? How can we bring together Muslims and Jews and Christians to work together to actually help innocent people? And then here he is just murdering two people in cold blood.”

Last week, the Capital Jewish Museum was one of the local nonprofits in Washington awarded funding from a $500,000 grant program to increase its security. The museum’s leaders were having concerns because it is a Jewish organization and due to its new LGBTQ exhibit, according to NBC4 Washington.

“We recognize that there are threats associated with this as well,” Executive Director Beatrice Gurwitz told the TV station. “And again, we want to ensure that our space is as welcoming and secure for everybody who comes here while we are exploring these stories.”

The Jewish Federation of Greater Washington said in a statement that they are horrified by the shooting and “mourn the loss of the two individuals killed in the attack.”

“Our hearts are with their families and loved ones, and with all of those who are impacted by this tragic act of antisemitic violence,” the federation said.
