Depending on the CSI unit's division of duties, it may or may not analyze evidence in the laboratory. The following article explores a homicide scene at a convenience store/gas station at 3 a.m. The survey material is represented by a number of visible elements. evidence, the body with an apparent gunshot wound to the chest and the testimony of the first officer at the scene.
