Forensics III
Students in this course will continue to learn about detecting, collecting, preserving and analyzing evidence. They will learn about DNA, fingerprinting, drug identification and toxicology, tool marks, ballistics, blood and blood spatter, and death. Students will gain hands-on experience in laboratory and practical application as necessary.
