Several Belgian news outlets have reported that Myriam Ullens de Schooten, 70, died following a confrontation with her stepson, Nicolas Ullens, a former Belgian spy, early Wednesday morning.
On Thursday, Walloon Brabant Public Prosecutor’s Office said Nicolas Ullens turned himself in and confessed to killing her over an ongoing inheritance dispute. According to the Brussels Times, he fired six shots into the car where Myriam and her husband were.
He will appear in court on April 3.
Myriam Ullens founded Maison Ullens in 2009, and the fashion label collaborated with designers Véronique Leroy and Haider Ackermann. The house has stores in New York City, Paris, and Aspen, Colorado.
A baroness, entrepreneur, art collector and philanthropist, Myriam Ullens was the second wife of Baron Guy Ullens de Schooten Whettnall, 88, also an art collector, whose leg was injured in the attack.
The Ullenes, who were friends with Belgian and British royalty, were well-known in the international art world, and co-founded the Ullens Centre for Contemporary Art in Beijing, China's first institution devoted to contemporary art.
