Over 300 people gathered on Sunday at the Sonian forest in a show of support to the parents of missing Belgian Natacha de Crombrugghe (28).
The parents are still looking for their daughter who disappeared while backpacking in Peru in January.
The participants were wearing green in a sign of hope. Just prior to taking off, they formed the hashtag #LookingForNatacha, Belga News Agency reports.
"I came first as a parent, because my son travelled to Australia two years ago, just after a Belgian boy had disappeared in Australia," one participant told Belga. "I wanted to express my support to the parents who are going through this pain of not knowing where their child is, and I also came to support friends who know Natacha's parents very well."
Some of them are currently in Peru looking for Natacha.
The father of Théo Hayez, a Belgian backpacker who went missing in Australia in 2019, was also present at the march.
"It is also to maintain the attention on her disappearance, so that the Belgian and Peruvian authorities continue their efforts to find her," another participant close to the family said. "They are ready to accept a death, but as long as Natacha is not found alive or dead, there is always hope and a case, just as there has been for the father of Theo Hayez for three years. For Natacha, it has only been four months. The criminal track remains open, and kidnapping is examined."
