Every Detail of a Stop Matters
Independent investigation supporting a DUI defense, from field procedure review to witness identification, statewide.
DUI Defense Investigation in Tennessee
A DUI case often turns on details that never make it into the arresting officer's report — the actual conditions of a field sobriety test, whether stop procedure was followed correctly, or a witness who saw something the state's account doesn't include. Delator Group's DUI defense investigation service reviews these details independently, for Tennessee criminal defense counsel building a defense that goes beyond simply challenging the breathalyzer number.
Our investigators, many with law enforcement backgrounds, understand what proper stop and arrest procedure actually looks like — which makes it easier to identify where a specific case's procedure may have deviated from it, and to locate witnesses or evidence the initial police report didn't capture.
What a DUI Defense Investigation Can Uncover
Inconsistencies between the police report and available dashcam or bodycam footage
Field sobriety test administration that didn't follow standard procedure
Witnesses at the scene who weren't interviewed by law enforcement
Questions about the stop's initial justification or probable cause
Chain-of-custody issues with breath or blood test evidence
