The M-Vac System

December 17, 2014 By Alice

m-vac systemThe M-Vac System is a wet-vacuum based forensic DNA collection device that is helping investigators solve more crime. It has been used on dozens of cases and has produced DNA profiles many times when traditional methods such as swabbing and cutting have failed to produce viable results. It is ideal for touch DNA scenarios, and can capture many times more DNA material than other methods from porous surfaces like clothing or other fabrics as well as rough surfaces such as rock, brick or concrete.

As my friend Jared Bradley explained here the use of the M-Vac System, despite having a higher initial cost than a swab, can save an investigation thousands of dollars.

  1. the M-Vac System is much (usually 20-30 times) more effective at collecting DNA material off porous and/or rough surfaces such as fabrics, rocks and cement
  2. It has been shown to collect over 22 times more DNA material (saliva) off of cotton, a common material for T-shirts, even after the swab had already sampled the stain
  3. The M-Vac System can collect DNA material from a larger surface area than the swab, and an even larger percentage compared to cutting

Here is a clip that explains even more about this new method that has become THE saviour in old cold cases. If forensics interest you, follow their blog!

Author Notes

On this website, I write about old, unsolved cases. Most are from the pre-DNA era and are in need of renewed media attention. I only do research and leave the active investigation of these cases to the professionals.

My posts are about homicides, missing and unidentified people, wrongful convictions, and forensics as related to these cases.

On book reviews: I only review select works of true crime, crime fiction, and historical fiction/mysteries. The stories have to fit my website's theme and research. It remains my prerogative to not review a book.

My database has over 325 cases listed by the victim’s last name. You will find a brief description there as well. The database will always be free to the public to use. You cannot buy ad space on my website, ever.

All writing suggestions that come in by email are added to my to-do list in the order in which they were received. Please be patient. My to-do list is very long but no case gets dropped and I will get back in touch.

Defrosting Cold Cases is NOT an organization. It is my brainchild.

If you have any questions about my website please check the Frequently Asked Questions (FAQ) page, the about page, and the tabs in both menu bars. If you still cannot find the answer there, please contact me.

Thank you,

Alice de Sturler

Richard Lapointe

In March 2015, the Connecticut State Supreme Court ordered a new trial for Richard lapointe. On Oct 2, 2015, International Wrongful Conviction Day, Richard was set free. The judge ruled that he cannot be retried for the 1987 rape-murder of Mrs. Bernice Martin. Richard Lapointe died on Aug 4, 2020 of Covid19 complications.

In 1987, someone killed Bernice Martin. I hope that she will not become a forgotten file.
