Forensic Technology: Advances and Challenges in Criminal Investigation

Definition and Contextualization of Forensic Technology

Forensic technology is an interdisciplinary field that integrates scientific tools, techniques, and methodologies for the collection, analysis, and interpretation of evidence, both in the physical and digital realms. This discipline is fundamental for reconstructing events, identifying suspects, and consolidating evidence in judicial proceedings.

Within this area, two specialties stand out:

• Digital Forensics: Focuses on the analysis of electronic devices, allowing the extraction and analysis of crucial data.
• Cyberforensics: Specialized in digital environment crimes, such as intrusions, fraud, and malware attacks.

Those interested in specializing can explore the Master’s in Cybersecurity and Cyberforensics, which provides advanced training in this field.

Forensic Technological Advances

In recent decades, the field of forensic technology has undergone radical transformations. Advances have not only streamlined investigative processes but have also elevated the value of evidence in trials.

• Modern DNA Analysis:

  Techniques such as next-generation DNA analysis (NGS) and touch DNA allow profiles to be obtained from minimal samples, facilitating the identification of victims and perpetrators.

• Computerized Forensic Ballistics:

  The use of algorithms and integrated databases allows for precise comparison of projectiles and casings, connecting weapons to crime scenes.

• Photogrammetry and 3D Scanning:

  These technologies document crime scenes in great detail, generating virtual models for accurate reconstructions during trials.
