New Research on “Touch” DNA
Unfortunately this data doesn’t include any statistics of what happens when the investigators use a more efficient collection method, but it’s interesting data nonetheless. What we find significant is that by changing the collection method, particularly using wet-vacuum collection vs swabbing, the entire equation and ensuing results are dramatically affected and usually improved. Wet-vacuum forensic DNA collection is changing many outcomes and absolutely needs to be incorporated into every lab’s processes.
As the sensitivity of DNA analysis increases, scientists are able to develop profiles from ever-smaller samples of DNA. This has lead to testing of a wider array of samples collected from crime scenes, including window panes, bullets, hats and other clothing, cigarette butts, and many other items.
Attorneys sometimes ask me about the likelihood of obtaining a useful DNA profile from certain items of evidence. A study from six European forensic laboratories may give some idea of how likely it is to find a DNA profile on items commonly found at crime scenes. This article contains an interesting chart that lists the item and the likelihood of finding a full profile, usable partial profile, possibly usable partial profile, or no profile. It seems best to use this type of information as a rough guide, but it is interesting nonetheless.

Happy New Year!
M-Vac Systems would like to wish all our friends, customers and supporters a Happy New Year and hope everyone has a fantastic 2016!
This past year has been another record year for us, and we are moving into 2016 with exciting momentum. There were over 30 cases worldwide where the M-Vac was instrumental in creating a DNA profile, and we’re confident there were more that we haven’t heard of yet but will eventually be revealed.
For those labs and agencies that purchased and/or used an M-Vac System in 2015, we thank and congratulate you! You are in a forward thinking category of being an early adopter of this new forensic DNA collection method, and you should be proud of your willingness to do whatever it takes to solve crime.
Moving forward the M-Vac is clearly setting a new standard in DNA collection as it consistently outperforms traditional methods and enables investigators to swing again at solving cases. Creating another chance is all most of them want, and we are proud to be able to provide that for them.
Please know that we are always available to help and answer any question you have about the M-Vac! We pray for your success and justice for the many victims you represent.
We look forward to further working with you and making 2016 the best year ever!
M-Vac Systems staff
