As violent crime escalated in the city and its suburbs, The Atlanta Journal-Constitution sought to uncover why so many of them took place at certain apartment complexes.

Reporters embarked on a year-long effort which included collecting crime data from 15 area law enforcement agencies and code enforcement records from 19 jurisdictions. They also analyzed lawsuits, property records, corporate documents and files from local and state housing agencies. More than 250 persistently unsafe and unhealthy apartment complexes were identified.

The findings are detailed in a three-part series, Dangerous Dwellings, available free on AJC.com and the AJC ePaper.
