Case Studies

Strategic Expert Analysis That Strengthens Legal Cases

Explore how my expert analysis has led to favorable outcomes in West Virginia and other jurisdictions.

Case Study #1
Wrongful Arrest & Excessive Force

An individual in West Virginia filed a lawsuit claiming wrongful arrest and excessive force during a routine stop. I analyzed video footage, arrest records, and officer statements to assess procedural violations. My report highlighted critical missteps in the officer’s actions that violated standard protocols, aiding the plaintiff’s legal team in negotiating a substantial settlement.

Case Study #2
Excessive Force in a High-Profile Arrest

A civil rights attorney sought expert analysis on whether law enforcement's use of force was justified. I reviewed body cam footage, use-of-force reports, and policies to assess compliance. My expert breakdown revealed inconsistencies between policy and the officer’s actions, strengthening the attorney’s case and contributing to a favorable settlement for the client.

Case Study #3
Officer-Involved Shooting Review

A defense attorney required an expert witness to analyze an officer’s decision-making in a fatal use-of-force incident. I examined dashcam footage, training records, and threat perception. My analysis demonstrated that the officer’s actions aligned with legal standards and department policies, playing a key role in securing a dismissal of charges against the officer
