How We Can Help You

We prepare attorneys to thoroughly understand the science (or lack of science) at issue in forensic evidence. We empower them to be able to competently interview and cross-examine prosecution experts.

We assist you in deciding what the proper direction may be regarding the evidence, both in your duty to investigate and to develop a strong theory of your case. We help craft a comprehensive approach to discovery, so that you are not left with trying to defend a case based on a one or two-page conclusory report. 

We also provide extensive support on pre-trial litigation strategies – from motions drafting to identifying outside defense experts to crafting the strongest arguments to persuade judges and juries of the value or lack of value of forensic evidence.

DNA & Serology

In the area of DNA evidence, FDS can provide a comprehensive independent review of the prosecution’s testing results using not only our understanding and experience, but also using the same types of software used by government laboratories to analyze DNA evidence. In every case with DNA evidence, FDS provides the following review and assessment:

Discovery Review

A full DNA discovery should adhere to standard operating and quality assurance procedures. FDS can provide support in drafting arguments, cross-examination chapters and preparing exhibits for trial.

Understandable Analysis and Report

We outline the meaning of the evidence and identifying defense strategies to attack and/or use the DNA evidence.

Expert Proficiency Performance Review

Laboratory audits should validate processes and evaluate irregularities such as contamination incidents within laboratories. FDS can provide recommendations for independent testing and retesting of evidence.

Pattern Matching & Other Forensics

In the areas of Pattern Matching and Other Forensics, FDS provides a comprehensive independent review of the prosecution’s reports and expert disclosures. FDS has been at the forefront of assisting in admissibility challenges and advocating for forensic reform efforts to address the shortcomings of many “forensic science” disciplines. In each case, FDS provides an assessment of the strength and weaknesses of forensic evidence and lays out possible strategic paths to dealing with this evidence.

Discovery Review

Forensic discovery should be complete with testing documentation, bench notes and underlying bases of opinions. With the proper discovery in hand, FDS can provide support in drafting arguments, cross-examination chapters and preparing exhibits for trial.

Admissibility Challenges

FDS has assisted with cases where admissibility challenges have been brought in Federal and State courts to exclude opinions regarding fingerprints, firearm toolmarks, “aged canine scent detection,” and arson pattern evidence.

Trial Strategies

FDS works with trial teams to develop the most comprehensive defense theory, well-crafted arguments and cross-examination chapters when Pattern Matching and Other Forensic evidence may be coming in at trial.


Chris McKee has been a valuable resource for me in preparing complex cases for trial. With his help, patience and explanations, two clients- one accused of murder and one accused of six counts of sex assault on a child- were found not guilty and got to go home to their families. He has assisted me in cases involving DNA mixtures, pattern matching, and crime lab policies and procedures. His ability to quickly spot issues and provide guidance is a fantastic resource, but he is also able to consult with attorneys and experts across the country to assist in litigating emerging issues in different jurisdictions.
Steve and I worked together on a federal bank robbery case where he was appointed as a DNA expert. He analyzed the Government's DNA results and quickly determined the quality of that evidence and the likelihood of challenging the DNA tests at trial. His advice was crucial in understanding the strength of the prosecution case. His combination of scientific knowledge and trial lawyer expertise is amazing. I can't imagine doing a DNA case without someone of his ability.
