This chapter examines the multifaceted response to missing persons cases, tracing what happens from the moment a report is made to the police. It explores how police, search and rescue (SAR) volunteers, emergency personnel, community organizations, and media actors each contribute to the work of finding, revealing a collaborative and supportive system. The chapter dives into the investigative processes and search practices that underpin these efforts, including risk assessments, interagency coordination, and the use of emerging technologies such as digital forensics, geolocation, and social media tracing. Ultimately, it shifts the focus from the high-profile disappearances to the often unseen, methodical, and deeply human work that defines most missing persons responses, work carried out quietly by the many, whose efforts together impact who is found and how.
