Definition
A case file is the comprehensive collection of all documents, evidence records, photographs, witness statements, forensic reports, and investigative notes related to a specific criminal investigation. In detective work, the case file serves as the central repository of information, allowing investigators to track leads, identify patterns, and build prosecutable cases. Files typically include initial incident reports, crime scene photographs, autopsy reports, interview transcripts, evidence chain-of-custody logs, suspect background checks, and investigative timelines. Detectives add to case files continuously as investigations progress, creating a chronological record of all actions taken. The organization and maintenance of case files is crucial—poorly documented files can result in lost evidence, missed connections, or cases being thrown out of court. Modern case files exist in both physical and digital formats, though many detectives still maintain paper files for quick reference. The case file becomes the foundation for trial preparation, with prosecutors relying on its documentation to build their arguments.
Historical Context
Systematic case file documentation emerged in the late 19th century as police departments professionalized and adopted bureaucratic procedures. Before standardized filing systems, investigations were often documented haphazardly, with crucial information lost or forgotten. The 1920s-30s saw the development of modern case file protocols, influenced by J. Edgar Hoover's systematization of FBI procedures. During the noir era of the 1940s-50s, case files were entirely paper-based, stored in filing cabinets in detective bureaus. The manila folder stuffed with documents, photographs, and evidence tags became an iconic image of detective work. Detectives developed personal systems for organizing files, with experienced investigators able to recall details from cases years old by reviewing their files. The introduction of photocopying in the 1950s-60s revolutionized case file management, allowing easy duplication and distribution. Modern digital case management systems have transformed file keeping, but the fundamental purpose remains unchanged—creating a complete, accurate record of investigation.
In Detective Work
Detectives spend significant time maintaining and reviewing case files. A typical homicide file might contain hundreds of pages by the time a case goes to trial. Investigators must document every interview, every piece of evidence collected, every lead pursued, creating a paper trail that can withstand legal scrutiny. Case files are reviewed during daily briefings, with detectives looking for connections between cases or patterns that might indicate serial offenses. Cold case investigations rely entirely on old case files, with detectives reviewing decades-old documentation looking for leads that original investigators missed or new forensic techniques that might apply to old evidence. File organization varies by department and individual detective preference, but all systems must allow quick retrieval of specific information. Detectives protect case files carefully—they contain sensitive information about victims, witnesses, and investigative techniques. Access is restricted and logged. The quality of case file documentation often determines whether cases can be successfully prosecuted.
In Noir Fiction
Case files appear throughout noir literature and film as physical manifestations of the detective's work and obsession. In "The Maltese Falcon," Sam Spade's office contains filing cabinets full of case records. Noir cinematography frequently features scenes of detectives reviewing files late at night, photographs and documents spread across desks under desk lamps, cigarette smoke curling through the light. The worn, overstuffed case file became a visual symbol of the detective's burden—each file representing human tragedy and moral complexity. Raymond Chandler's Philip Marlowe keeps meticulous files despite his cynical exterior, suggesting professionalism beneath the hardboiled facade. Noir narratives often feature scenes where detectives discover crucial connections by reviewing old case files, or where files are stolen or destroyed to obstruct investigations. The case file represents institutional memory and the detective's commitment to justice, even when the system itself seems corrupt. Contemporary neo-noir continues using case files as visual and narrative elements, though now they might be digital databases rather than manila folders.

Examples in Context
A detective pulls a three-inch-thick case file from the cabinet, spreading crime scene photographs, witness statements, and forensic reports across her desk, cross-referencing the current murder with a similar unsolved case from two years ago, finding the pattern that connects them and identifying a serial killer the department didn't know existed. In another scenario, a defense attorney demands to review the complete case file during discovery, forcing detectives to ensure every piece of evidence is properly documented and every interview accurately transcribed, knowing that any gap or inconsistency could result in their suspect walking free. In OnlinePuzzle's Daily 5, a player solves "CASE FILE" as a clue answer, immediately understanding its connection to the game's overall detective theme, recognizing how this term represents the organized, methodical approach to investigation that transforms scattered clues into coherent narratives and solved cases.
