Death investigation is the process of examining the circumstances surrounding a person's death to determine the cause and manner of death. This investigation is typically conducted by a coroner or medical examiner, who collects evidence, reviews medical history, and may perform an autopsy. The goal is to establish whether the death was due to natural causes, an accident, suicide, or homicide. In addition to forensic analysis, death investigations often involve interviewing witnesses and gathering information from law enforcement. This comprehensive approach helps ensure that all relevant factors are considered, providing clarity for families and legal authorities regarding the deceased's final moments.
