<s>[INST] Murphy, a detective, is assigned to investigate a narcotics ring. After looking at the ring's criminal history and its pattern of engaging in violent activities, Murphy develops a profile of the ring's trends and casual nexus connections between the relevant groups and their associations.

Murphy then analyzes the group's financial status by monitoring the money flow through suspicious transactions that appear unwarranted. Murphy is able to determine that the money flow is coming from a suspected local organized crime group. He believes that the money is laundered or used for illicit purposes. Murphy then plots the geospatial mapping of the group's key players and relevant organizations to visually depict trends, which helps him identify clusters, modus operandi, and group associations.

Murphy uses this investigation method to not only focus on apprehending the ringleaders but also to disrupt the organized crime group laundered money flow. What investigation method is Murphy using?[/INST]
