What you need to know

The Massachusetts Violent Death Reporting System (MAVDRS) collects and links data on all violent deaths within the Commonwealth. It includes detailed information on homicides, suicides, legal intervention deaths, unintentional firearm deaths and deaths of undetermined intent. MAVDRS is an incident-based system and links victims and suspects associated with a given incident in one record.
The system combines information from death certificates, medical examiner records, toxicology reports, police reports and crime laboratory reports. Individually, these sources explain violence only in a narrow context; together, they provide comprehensive answers to the questions that surround violent deaths: who, what, when, where, and, in many cases, why. No other system offers this benefit.

This standardized database is part of the National Violent Death Reporting System (NVDRS) developed and funded by the Centers for Disease Control and Prevention through Grant #U17/CE002606. Its contents are solely the responsibility of the authors and do not necessarily represent the official views of the Centers for Disease Control and Prevention.
