"If you know where exactly a perpetrator touched something, then yeah, you could swab something. But most of the time we don’t know so it’s better if you have something that is cloth or fabric or a rope, some sort of ligature, bricks and rocks, things like that, wooden boards, I would always recommend the M-Vac versus swabbing just because I’ve seen the results! It’s not just a theoretical thing. I know what it can do. I know you can get some pretty amazing results using M-Vac. So the more I use it the more I’m a proponent of it for sure." --Suzanna Ryan, Laboratory Director/Forensic DNA Analyst, Pure Gold Forensics
