CDC's National Violent Death Reporting System & Coroner/Medical Examiner Partners [open pdf - 577KB]
From the Document: "The Centers for Disease Control and Prevention's National Violent Death Reporting System (NVDRS) links details of violent deaths - the who, when, where and how - and shares insights into why they occurred. NVDRS relies on information from coroner/medical examiner reports (including toxicology), law enforcement reports, and death certificates to pool anonymized data on violent deaths and their circumstances into one database. Such data are far more comprehensive than what is available elsewhere and decision-makers and program planners can use this information to develop and tailor violence prevention efforts."
