This review article describes the role of the medicolegal death investigator and medical examiner or coroner (MEC) in the investigations of a sudden unexpected infant death (SUID) beginning with an introduction into the case types that should be investigated and how infant deaths fit into that legal framework. The article also provides an overview of the history of the Centers for Disease Control and Prevention SUID investigation guidelines and process. The article concludes with a description of how the MEC correlates the scene investigation with autopsy findings, as well as the role of the MEC in cause of death determinations. There is also a brief discussion on how infant mortality data are captured and subsequently used to decrease infant mortality. [Pediatr Ann. 2017;46(8):e297-e302.].
