The Inquirer reconstructed details of the shooting death of Thomas Hennelly 3d through dozens of interviews and examination of Philadelphia Police Department and District Attorney's Office records that typically remain secret, but that were made public in a federal civil rights lawsuit filed by his estate.

Those documents included transcripts of depositions from police officers and supervisors, Internal Affairs reports, personnel records, and performance reviews.

In addition, reporters listened to 911 calls and police radio conversations among officers and a dispatcher during the incident. They obtained footage from surveillance cameras at the shooting scene and reviewed toxicology reports from the Medical Examiner's Office.

The police declined to make available officers and supervisors involved in the incident. Officer Saniyyah Jones did not respond to repeated requests to be interviewed.
