DULUTH — When the only remaining Modern Orthodox Jewish synagogue in the northern Minnesota-Wisconsin region burned to collapse on Monday, Aug. 9, it struck chords around the world — appearing on nightly newscasts and gaining an outpouring of support on social media.

“Thinking of our friends in the Duluth Jewish Community today,” tweeted Sen. Amy Klobuchar in the wake of the fire that claimed the Adas Israel Congregation synagogue but spared more than half of its sacred, handwritten Torah scrolls.

For New York author Sarah Rose, the event hit her at her core. She calls Duluth her ancestral home. While growing up, she spent holidays at the synagogue around a slew of “spinster-aunties,” cousins and other relatives from the Twin Ports to the Iron Range. She took to Twitter, saying her great-great-grandfather helped build the synagogue.

“I was absolutely devastated,” Rose said. “The most terrifying image to any Jew anywhere is a synagogue on fire. It is what our nightmares look like.”

The Duluth police and fire departments along with the Bureau of Alcohol, Tobacco, Firearms and Explosives are conducting an investigation into the cause of the fire. Police Chief Mike Tusken confirmed two people of interest were interviewed Monday.

At a 4 p.m. news conference Tuesday at City Hall, authorities had little new to share but reiterated their commitment to the investigation.

"This has been certainly very difficult for our Jewish community to have lost this place of worship," Tusken said. "So, it's with that that I speak about (how) we are working in earnest to have a resolution on this. We know that this is important not just for the city of Duluth but for that community of faith."

Tusken said police "hit the ground running" on Tuesday morning with help from the ATF, which he said has technical expertise beyond the Duluth Police Department's.

Tusken also shared the ATF's tip line; anyone with information related to the fire is asked to call 1-888-283-3473.

The number of investigators working on the case has quadrupled to about 20, and Tusken said police are canvassing the neighborhood to try and connect with nearby residents who might have seen or heard something. Investigators also are reviewing hundreds of hours of surveillance video from nearby businesses and residences.

New evidence was recovered from the site of the fire on Tuesday, Tusken said, but he offered no additional details.

"I will say that there is no indication right now that there is a threat to other places of worship," Tusken said.

Cleanup efforts continue at the site, and some preliminary demolition has begun, Duluth Deputy Fire Marshal Jon Otis said Tuesday, adding that the fire department is encouraging people to avoid the area, if possible.

"We have taken steps to demolish parts of the building that were potentially unsafe, to help mitigate some of those risks," Otis said. "We also have worked to move some debris off city streets."

The Adas Israel Congregation issued a statement through a board member on Tuesday, addressing a cloudy future.

“The plan moving forward is uncertain and probably a long way off,” board member Mike Baddin said in the statement.

He warned of grassroots efforts to raise money for the synagogue amid concern for false crowdfunding pleas.

“Nobody affiliated with Adas has set up any type of GoFundMe page nor have any steps been taken to solicit contributions,” a news release said.

“The Adas board has not convened, but I have knowledge that no requests for financial donations have been solicited and I do not believe that will happen,” Baddin said. “Generosity is always appreciated, especially now.”

The surest way to send monetary support is by mail directly to the synagogue at 302 E. Third St., Duluth, MN 55805.

Even the notion of possible criminality unbalanced Rose.

“We felt very welcome in Duluth, never an unkindness towards us at all,” she said. “That’s part of why it’s so terrifying for me. I see it as a touchstone for everything good — being a Midwestern Jew.”

Rose grew up in Chicago, visiting Adas Israel Congregation synagogue with her family multiple times a year. She’s cousins with the synagogue’s president, David Sher.

Together with Rose’s 87-year-old mother, Helen Cohen Rose, the story of the Adas Israel Congregation came into view from its origins four generations ago. Helen was raised in Superior and lived in Chicago until moving to assisted living closer to her daughter in New York.

“I was happy to hear they saved the Torahs,” Helen said. “We’re Jews, we go on and we rebuild. We’re fortunate to have the Torahs to build around.”
