Hello, all! So happy you are joining me for my “limited series,” Forensic Fridays. I hope you’ll continue join me over the next few weeks as I share info about forensic and law enforcement procedures that have made their way into my books.
Among the many things I’ve learned about evidence is the importance of its preservation. It’s crucial that the crime scene is protected and secured. Proper protective gear must be worn (latex gloves, booties), and anyone entering the scene must be logged in and out. One thing I hadn’t thought about that surprised me — and may surprise you — is that, while much evidence is secured in plastic bags, DNA evidence must be kept in paper containers so it can breath. If the container can’t breath and moisture builds up, the DNA will be degraded or ruined.
Alex shifted his attention to the kitchen and moved carefully past the breakfast bar. He saw his sister, Georgia, dressed in a Tyvek suit and booties, her red hair tucked into a surgical cap as she leaned over the body, snapping photos. Blood pooled around the body and under Georgia’s feet. Judging by Georgia’s equipment and grim face, she had been here several hours documenting the scene. He knew this because she would never had stepped into the blood and disturbed the evidence until it was well documented . . .
Georgia stepped out of the blood pool onto a tarp, where she rolled her head from side to side. Crime scenes like this one could take days to process.
