Killing of Peter R. de Vries
The Dutch police arrested three suspects the same day of the shooting. Two suspects were in a car that was stopped on the A4 motorway near Leidschendam. The third person was released the next day, and is no longer a suspect. A 35-year-old Polish man, Kamil E., is the suspected getaway car driver, while a 21-year-old Dutchman, Delano G., is the suspected shooter. Dutch media has reported that the suspected killer is the nephew or cousin of one of the henchmen of Ridouan Taghi, known as the Netherlands' most-wanted criminal. De Vries was involved in the prosecution of Taghi.
