Advanced Latent Print Techniques
Course Description: This course provides instructional training in the advanced techniques in proper sequencing and development of latent prints. Students will process a multitude of non-traditional items, in non-traditional elements. They will also be able to utilize advanced chemical processes, and the utilization of an Alternate Light Source as development techniques. Lecture with PowerPoint presentations, classroom demonstrations, and discussions as well as student practicum exercises will be utilized.
This course is instructed by members of the Pennsylvania State Police, Bureau of Forensics Services.
Instructional Hours: 3 Days/16 hours
