Detectives have now identified a suspect: 27-year-old Illias K., who denies the charges but has been detained. Judicial sources question whether this was a targeted burglary as other items too were stolen. The suspect isn't linked to the Brussels attacks or any of the victims either.
However, Illias K., is a jihadi who fought in Syria and later returned to Belgium after he was injured. At one point he admitted beheading a man in Syria. He was recruited by Jean-Louis Denis, a notorious figure who recruited numerous jihadis in Belgium, and Khalid Zerkani, who was involved in similar practices. In 2016 Illias K. received a 5 year sentence for being a member of a terrorist group. Half the sentence was suspended. He was never prosecuted on account of the alleged beheading.
