The summer spike in killings is just one of several findings unearthed in an analysis by The New York Times of multiyear homicide trends. The information — detailing homicides during the years 2003 to 2008 — was compiled mainly from open-records requests with the New York Police Department, and a searchable database of details on homicides in the city during those years is available online for readers to explore at nytimes.com/nyregion.
Each day, the New York Police Department announces major crimes, including most homicides, in the five boroughs. This data is compiled from those reports, in addition to news accounts, court records and additional reporting. The map will be updated as new information becomes available.
