Pieter Vorstedt is the secondary antagonist in the 1989 film Lethal Weapon 2. He is the right-hand man to Arjen Rudd and the man who murdered Riggs' wife during Riggs' earlier case as a cop and thus indirectly responsible for making Riggs suicidal and dangerous in the first film and overall shaping the character of Riggs in the franchise. He is portrayed by Derrick O'Connor.
