Study Notes

Criminalistics and Forensic Science

Criminalistics: The scientific study and application of various disciplines to assist in criminal investigations.
Primary Purpose of Physical Evidence: To serve as factual evidence that can link suspects to crimes or exonerate innocent individuals in judicial proceedings.

Forensic Professionals

Forensic Chemist: A scientist who analyzes materials related to crime, using chemistry to identify substances and find evidential insights.
Forensic Anthropologist: Specializes in the identification and examination of human skeletal remains; assists in determining age, sex, ancestry, and trauma.
Forensic Odontologist: Focuses on dental records to identify human remains and analyze bite marks.

Legal Responsibilities

Witness Responsibilities (Dr. Broudel's Advice): A person made a witness by law should cooperate with legal processes and provide accurate testimony.

Functions and Focus Areas

Primary Function of Forensic Science: To apply scientific methods and principles to investigations, providing objective analysis that aids legal proceedings.
Focus of Forensic Chemistry: Concentrates on the chemical analysis of substances found at crime scenes, including illegal drugs, toxins, and trace evidence.

Evidence Handling and Communication

Role of Forensic Chemist in Evidence Collection: Ensures proper collection, preservation, and documentation of specimens for reliable examination.
Golden Rule "Go Slowly": Encourages meticulous attention to detail and patience in analyzing evidence to avoid errors.
Scope of Forensic Chemistry and Toxicology: Encompasses the analysis of poisons, drugs, and other toxic substances in relation to criminal cases.

Communication and Reporting

Forensic Chemist in Communication of Results: Must clearly present findings to law enforcement and legal parties, ensuring understanding and clarity in how results relate to the case.
Toxicology Focus: Primarily studies the effects of substances on biological systems and determines their role in causing harm or death.

Emphasis and Procedures

Forensic Chemistry's Legal Emphasis: Aims to address and resolve legal questions using scientific findings related to chemical substances.
Significance of Individuality in Evidence Collection: Maintaining the distinct characteristics of evidence is crucial for forensic analysis to ensure its integrity and validity.

Court Presence and Documentation

Forensic Chemist during Court Appearances: Provides expert testimony, explaining analyses and findings to the court and validating their methodologies.
Golden Rule "Take Note": Implies documenting each step of the analytical process for accuracy and reproducibility in forensic work.
