Warm tributes have poured in for a much-loved former Brussels-based journalist who has died at the age of 55, in circumstances that colleagues describe as both tragic and profoundly revealing of her character.

Karen Carstens died after sustaining injuries in a house fire in the United States, having reentered the burning property in an attempt to save her cats.

Emergency services say the fire broke out in the basement of her home at around 5:45 a.m. on April 7, according to Montgomery County Fire and Rescue. Two cats were inside at the time. One died, and the other was located later that day. Carstens was rushed to a local hospital but did not survive her injuries. The only other occupant of the house, her brother, escaped.

According to reports in The Washington Times, firefighters were initially told that no one remained inside the house. Carstens and her brother had apparently evacuated, but she returned to the property to retrieve one of the cats. Authorities believe the fire was accidental. Investigators have also indicated that the home did not have functioning smoke alarms. The exact cause remains under investigation.

Carstens was born in Washington, D.C., and studied at the University of Maryland, where she earned a degree in multimedia journalism. She later moved to Brussels to work for the now-defunct European Voice, a publication that once served as a central forum for reporting on European Union affairs. In addition to her staff role, she freelanced for a range of city-based outlets, building a reputation as a thoughtful and energetic reporter.

After leaving Brussels, she returned to Washington, where she spent seven years writing and editing news and features, and producing a weekly electronic newsletter for the German Embassy. She later worked briefly as a health writer for the Military Health System’s Health.mil platform and as a communications consultant for the International Finance Corporation. From 2015 onward, she worked independently as a freelance writer, editor, and translator across North America.

Colleagues recall that she remained deeply connected to her time in Brussels. She was active on social media and recently wrote that she “missed all the anglophone writers and editors” she had worked alongside there, describing the city as a place she had been proud to “call home.”

David Cronin, a former colleague at European Voice, led the tributes. “Between 2002 and 2005, I spent many hours working and socializing with Karen in Brussels,” he said. “She was constantly smiling and seemed to have a boundless capacity for fun, cheer, and enthusiasm.

“The only time I can recall her being less than enthusiastic about anything was when she accompanied me to a gig by a band called The Cramps. The racket they kicked up wasn’t exactly to her taste.”

Cronin added that Carstens had a quiet but lasting influence on his personal life. “I owe an immense personal debt of gratitude to Karen,” he said, “as she persuaded me, gently, that I should join a gym. That was the first step I took toward properly looking after my health.”

Though they had not seen each other in person for nearly two decades, Cronin said he followed her life through her frequent posts online, many of them devoted to her cats. “It is deeply tragic that she died trying to rescue them,” he said. “At the same time, it shows that she was big-hearted right to the very end.”

James Drew, another former colleague, recalled her as “a very warm, kind, diligent, and intelligent person,” adding that she would be “very sadly missed.”

Dennis Abbott, who hired Carstens during his tenure as editor of European Voice, described his shock at the news. “Karen was a lovely person and a talented journalist,” he said. “She was a positive presence in the newsroom and someone I appreciated a great deal. It is hard to believe she is gone—I keep seeing her in my mind’s eye.”

They had remained in contact over the years via social media. “She loved her cats,” Abbott added, “and it seems she was trying to rescue one of them when she was overcome by the fire.”

Others echoed the sentiment. Peter Chapman described her as “one of the warmest humans I ever knew.” Craig Winneker recalled not only her professional contributions but also the sense of energy she brought to the newsroom. “Karen was a lively and fun person,” he said, “who brought more than just journalistic skill—she brought joy.”

After returning to the United States, Winneker said they stayed in touch online, sharing an appreciation for music and word games. “She was a fierce and highly skilled competitor in Words With Friends,” he added. “She will be greatly missed.”

Adrian Scally described her as “a great team player with a wonderful smile,” adding that “the world will be a little lonelier without her presence.”

A detailed obituary, prepared by friends and published by Carewell Cremations, paints a fuller portrait of Carstens’ life—one defined by curiosity, movement, and connection across continents.

“Karen’s life was a vibrant tapestry,” it reads, “woven from a rich array of passions, places, and profound connections.” From summers spent along the New Jersey shore to time in New York City and the landscapes of New Mexico, and later across Europe, she moved through the world with what the obituary describes as “compassion, insatiable curiosity, and zest.”

Washington, D.C., her hometown, remained central to her identity. It was there, the obituary notes, that her “spirit of political activism bloomed.” She attended protests and rallies, often documenting them through photography, and developed a lasting commitment to environmental causes.

Her German heritage also played a formative role. As a Fulbright scholar, she moved to Hamburg in 1997, later living in Frankfurt, experiences that deepened her sense of cultural and personal identity.
She was, by all accounts, a devoted participant in the arts. She frequented museums and exhibitions, attended concerts, and gravitated toward indie rock, including the music of fellow Maryland native Tori Amos. Food, too, served as a social anchor—meals and gatherings became opportunities to sustain friendships that often lasted decades.

Her relationships, the obituary suggests, were rarely fleeting. Even past romantic partners remained part of her extended circle. In her neighborhood of Brookdale, she was known for her warmth, especially with children, greeting them with enthusiasm during moments like Halloween. She cared deeply for her cats, Leo and Max, who were a constant presence in her life.

Intellectually, she was equally engaged. She shared with her father a deep interest in history and maintained what the obituary describes as a “voracious appetite for reading,” particularly long-form journalism.

Her professional life reflected that same breadth. From early studies at the German School in Washington, D.C., to a degree in politics from McGill University and multiple advanced degrees spanning journalism and European studies, she pursued storytelling in its many forms. She also taught German to American adults, extending her engagement with language beyond journalism.

Her career took her across the United States and Europe, including reporting roles in Maryland and positions in Germany and Belgium. She worked with outlets such as Der Spiegel, DPA, Frankfurter Allgemeine Zeitung, and the European Commission. Later, as a web editor for the German Embassy in Washington and then as a freelancer, she continued to produce work that ranged from healthcare reporting for U.S. military audiences to coverage of global manufacturing trends.

At the center of her life, however, were her personal relationships—particularly with her mother, Sarah. The obituary describes their bond as “uncomplicated and profound,” marked by shared routines such as watching period dramas and a shared sense of humor that extended to the entire family.

“Humor was a lifeline for Karen,” it reads, “a delight for her friends, and a light that she and her brother Karl wielded deftly even through dark times.”

The obituary concludes with a reflection that echoes many of the tributes offered by colleagues: “Today, we remember Karen not only for her remarkable achievements and passions but for the radiant spirit she shared so freely—with her family, friends, neighbors, and the wider world she chronicled with such devotion. Her life remains a testament to curiosity, compassion, and a joyous engagement with the world.”
