Services
The work behind the results
A defense attorney–client practice with two standards of proof. Licensed private investigation and judgment recovery on one side; court-qualified law enforcement expert witness review on the other. Because it takes one to know one.

Criminal Defense Investigation
Defense-side fact development, witness canvassing, records retrieval and exculpatory evidence review for attorney-client matters. Criminal-defense investigative work may also include discovery review, police report review, body-worn camera review, recorded interviews, CAD and dispatch records, radio traffic, investigative timelines, evidence documentation, witness follow-up, comparison of police narratives with available source evidence, and identification of investigative or documentation gaps — plus identification of additional records or evidence that may warrant further investigation. This is factual and investigative analysis for counsel’s evaluation; it does not include legal conclusions.
- 07
Judgment Recovery Services
Debtor and asset locates, bank account identification, employer discovery and garnishment support.
- 08
Cold Case Investigation
Fresh eyes on stalled family matters — missing persons, unresolved personal cases, and long-dormant civil questions. This work is for families and private clients, not law enforcement.

Law enforcement expert witness
For the questions only a cop can answer
Christine Burke is a former police sergeant, major case detective and court-qualified expert witness. She examines police policy, procedure and culture — and applies forensic genetic genealogy — for criminal defense, prosecution, personal injury and Section 1983 civil litigation across the United States.
The State brings the full weight of law enforcement to every case — the defense deserves an expert who knows that system from the inside.
