Day two of Biomed Forensic Week was filled with crime scene investigations. Corporal Russell Benefield Sr. came on behalf of the Mobile County Sheriff’s Office Crime Scene Unit. He thinks that the dead cannot cry out for justice so it is his duty of the living to do so for them. Responsibilities include identifying evidence, documenting evidence, processing evidence, and collecting evidence. Observations show natural or homicide. Photography is a very large part of the scene as this may be looked back on later to find things they couldn’t see in person. Examples of photos they could be: distance photos (overall scene), mid-range photos (slightly more in depth), close up photos (specific items), photos with evidence markers (identifying), and scales. Collecting data may lead the person to the direction of swings (how much force the swing was taken), ballistic trajectory shows angles (weapons,etcs), and bloodstain pattern analysis (interprets book in order to recreate actions). Processing evidence may use cyanoacrylate fuming and super glue with ultraviolet lights, ninhydrin spray for fingerprints, latent print recovery, and blood reagent spray (luminol, blue stars). Finally, collecting the evidence is crucial as they have to package bags, consider finger patterns, and any sort of casting of a tire/shoes/etc. Thank you Corporal Russell Benefield Sr. for coming out and teaching day two!
