Criminal Defense Investigation
Our criminal defense investigations specialize in post-conviction case reviews and capital punishment defense. We analyze forensic evidence, interview witnesses, and reconstruct crime scenes to challenge wrongful convictions. Our work has contributed to freeing over 20 wrongfully imprisoned individuals through meticulous examination of trial records and discovery of new evidence.
DNA Testing
We facilitate advanced DNA testing including Touch DNA technology for post-conviction cases. Our experts coordinate with accredited labs to re-examine biological evidence using modern techniques that weren't available during original trials. This service has been instrumental in overturning multiple death penalty convictions through conclusive genetic evidence.

We identify inconsistencies in official reports by analyzing physical evidence placement and trajectory patterns. This service helped exonerate David Camm through demonstrating misinterpretation of blood spatter evidence in his wrongful conviction.

Nov 16, 2017 Report
Hired them to serve papers for the law firm I work for. They attempted service 6 times all in the afternoon or evening. They knew the person resided in the home per neighbors, yet didn't try to serve the papers in the morning or try other methods to get them served. On top of that the fees were almost double what we customarily pay. Very disappointed!
