 In session with Dr. Kroger , Monk remembers details of the shooting . Monk and Natalie return to the roof where the shooting took place . Monk remembers that there was a walkie @-@ talkie in Kenworthy 's bag . He explains that Kenworthy contacted his ex @-@ cons to carry out a heist of the museum , with Kenworthy acting as the diversion , dropping toys to stop traffic . However , the robbery was ruined when Kenworthy was shot . That day was chosen for the heist because one of Kenworthy 's accomplices , Carl , was on duty in the museum at the time . As Carl realized his hours were not good to carry out a second heist , Kenworthy killed Dubois , so Carl could fill in for her .
