Crimes represent complex challenges for security and justice systems, requiring rigorous scientific methods for the elucidation and accountability of those involved. Analytical Chemistry plays a crucial role in the detection and identification of chemical substances and traces, using methods such as mass spectrometry, chromatography, and DNA analysis. This work investigates the relationship between Analytical Chemistry and forensic investigation, highlighting how analytical techniques are applied in solving crimes. The study addresses, through a literature review, the main forensic methodologies, focusing on their contributions to crime scene reconstruction and the collection of precise evidence. The research aims to understand how these tools assist the justice system by improving the reliability of forensic results in criminal investigations. The results demonstrate the relevance of analytical techniques in consolidating scientific evidence. It was found that the accuracy and specificity of the methods contribute to more effective investigations. The application of these tools strengthens the connection between science and justice.
