Initial response and investigation

Summary

This section of the College of Policing's Authorised Professional Practice outlines the critical initial steps police officers must take when responding to a missing persons case. The primary focus for the first responder is the safety of the missing individual, with immediate assessments of risk impacting the investigation's direction. Officers, designated as initial investigating officers (IIO), must begin efforts promptly by identifying possible locations for the individual and corroborating information collected. They should conduct appropriate searches and intelligence checks using systems like PNC and ViSOR. Continuous reassessment of risk and provision of support to the missing person's family or caretakers are also emphasized. Should any serious crime be suspected or if the missing person is under significant threat, the IIO is advised to notify a supervising officer without delay, ensuring systematic information gathering and engagement of necessary resources is prioritized.
