Crime Scene Forensics

Crime scene forensics is the discipline of properly collecting, documenting, preserving, and analyzing physical evidence from crime scenes. The integrity of physical evidence — and the credibility of the entire investigation — depends on following established protocols at every step, from initial scene assessment through courtroom presentation.

Proper evidence handling encompasses scene documentation, evidence identification and collection, chain-of-custody maintenance, evidence packaging and storage, and the ability to testify about these procedures under cross-examination. Failures at any stage can result in evidence being challenged or excluded from legal proceedings.

In both criminal and civil cases, the handling of physical evidence is frequently contested. Defense teams routinely challenge evidence collection methods, chain-of-custody documentation, and preservation protocols. Having investigators with certified forensic expertise can be the difference between evidence that withstands scrutiny and evidence that gets thrown out.

Evidence handling expertise is critical when you need to assess whether evidence in a case was properly collected and preserved, when your defense strategy involves challenging the prosecution’s evidence handling procedures, when your organization needs training on best practices for evidence collection and preservation, and when you need expert consultation on chain-of-custody issues for civil or criminal litigation.

Improper evidence handling doesn’t just affect individual cases — it can undermine institutional credibility and create liability. Organizations that handle evidence as part of their operations benefit from training programs that establish consistent, defensible procedures.

Members of MPM Consulting have been certified by the FBI as instructors on proper evidence collection techniques and the preservation of that evidence. This represents the highest level of forensic evidence expertise in federal law enforcement.

Mike McCall served as a member and Senior Team Leader of the FBI’s Evidence Response Team in Boston, where he was routinely responsible for the handling of evidence in high-profile investigations — ensuring chain of custody and proper preservation of exhibits. This hands-on experience gives MPM a practical understanding of evidence handling that goes far beyond textbook knowledge.

MPM offers a singular point of contact with the expertise to assist your defense litigation needs as they relate to proper evidence handling. We also provide classroom training programs covering best practices and lessons learned in evidence collection and preservation, tailored to the needs of law enforcement agencies, corporate security teams, and legal professionals.
