Meet Clark Olofsson’s Kids: Donegal Demuynck, Dorian Demuynck, David Demuynck and Others

Clark Olofsson, later known as Daniel Demuynck, is a notorious Swedish criminal whose high-profile crimes and repeated escapes made him one of Europe’s most infamous figures.

Born on February 1, 1947, in Trollhättan, Sweden, his life has been defined by a long criminal record that includes bank robberies, drug trafficking, and prison escapes. Olofsson was directly involved in the 1973 Norrmalmstorg robbery, which led to the creation of the term “Stockholm Syndrome.”

Despite a tumultuous life of crime, Olofsson also had a family. He married Marijke Demuynck, a wealthy Belgian woman, in 1976, while he was incarcerated in Kumla Prison. They had three sons—David, Donegal, and Dorian Demuynck—before divorcing in 1999.

Olofsson also fathered two daughters from earlier relationships and had another son with a later fiancée, Angelique.

Clark Olofsson grew up in a troubled home with alcoholic parents. After his father left and his mother became ill, he and his two younger sisters were placed in foster care. Raised in a nominally Christian Swedish household, Clark began committing crimes in his teenage years, leading to multiple prison terms.

In 1976, while on the run from authorities, Clark met Marijke Demuynck, born in 1957 to a wealthy Belgian family. They married that same year inside prison.

After Clark’s release in 1991, the couple settled in a 16-room villa in Belgium, raising their three sons there. Marijke provided a stable home environment despite Clark’s continued legal troubles. The couple divorced in 1999 following his 1998 drug smuggling arrest, but they reportedly maintained a cordial relationship.

David Demuynck

• Born: May 29, 1983
• Profession: Musician and Composer

David Demuynck is the eldest son of Clark and Marijke. Unlike his father, he pursued a respectable career in music, becoming a recognized jazz pianist and composer in Belgium.

He performs with the Viking Trio and collaborates with groups like the Muze Jazz Orchestra and the Presidents of Antarctica. David has a net worth estimated to be between $50,000 and $100,000, largely derived from his music career.

He shares parts of his life and music on social media, maintaining a public but grounded presence. Despite his father’s criminal legacy, David has built a life based on creativity and discipline.

Donegal Demuynck

• Born: March 5, 1985
• Profession: Undisclosed / Private Life

The middle son, Donegal, maintains an extremely low profile, with limited public information available about his personal and professional life.

He has no known social media presence and tends to avoid the spotlight. Some confusion has arisen from Clark’s alias Daniel Demuynck, with some mistaking it for Donegal’s identity—but Donegal is one of Clark’s confirmed sons.

Like his siblings, he was raised in Belgium and likely benefited from the stable environment provided by Marijke during Clark’s prison stints. Reports suggest he stayed in touch with his father through phone calls and prison visits.

Dorian Demuynck

• Born: November 12, 1991
• Profession: Undisclosed / Private Life

Dorian, the youngest son, was born just before Clark‘s release in 1991 and spent his early years in the family’s Belgian home.

Very little is known about his professional life or current whereabouts, and like Donegal, he has maintained total privacy, avoiding media and public platforms.

Despite the disruption caused by Clark’s 1998 arrest and long prison sentence, Marijke shielded their sons from public scrutiny and helped maintain a sense of normalcy. Dorian has never been publicly linked to any controversies or criminal activity.

Other Children

In addition to his three sons with Marijke, Clark Olofsson reportedly fathered:

• Two daughters from previous relationships (names and details unknown)
• One son with his former fiancée, Angelique (unnamed publicly)

These relationships remain largely undocumented, with Clark keeping these aspects of his personal life private.
