The two suspects arrested Monday on suspicion of supplying weapons to Richard K. in Weiteveen will remain in custody for two weeks longer. This was determined by the District Court of the Northern Netherlands. The 50-year-old Richard K. killed a couple in the village in Drenthe in January after an escalating conflict over a property. One of the suspects arrested Monday is a 41-year-old man from the municipality of Eemsdelta.
