In legal matters we work at the direction of counsel and operate as an agent of counsel for the duration of the engagement. All work product is attorney-client privileged and attorney work product.

If your matter requires experienced investigative support, this is where to start.

Experience That Knows Which Side It Is On

In criminal and post-conviction matters, we work on behalf of the accused, including pretrial criminal defense, post-conviction appeals, habeas corpus proceedings, and capital litigation. We locate and interview witnesses, develop records that were not part of the original case file, and investigate what was missed the first time around.

We also work civil rights and civil liberties cases, including constitutional claims. Those cases call for locating witnesses no one else found, obtaining records that were never produced, and developing patterns of conduct across other incidents and other cases.

For civil and family law matters we provide fact investigation and litigation support to attorneys on both sides of the caption, on a selective basis.

The work is conducted at the direction of counsel and documented as attorney work product.
