Chain of Custody and Its Importance

The Chain of Custody, or Evidence Transmittal Letter, is a very important document that must accompany your evidence when submitting samples to the laboratory for analysis. This is especially true if the case goes into litigation. It is also very important for other types of regulatory

Improved Vehicle Fluid Evidence Containers

Worried about shipping fuel samples?  Now you don’t have to!  Our new and improved sample containers are one ounce plastic jars, which are perfect for shipment of vehicular fluids to the lab.  The Department of Transportation (DOT) document 49 CFR §173.4 “Small quantities for highway and rail” states that class 3 materials (fuels) may be shipped via ground shipping, and is limited to a sample size of thirty (30) mL or one (1) ounce.  The full document can be found here 49 CFR §173.4.  Each of our kits come with prepaid FedEx and UPS ground shipping labels.  As long as you use one of our kits, you never have to worry about whether your sample is in compliance with DOT regulations.  Insider tip from the lab:  write “laboratory sample” on the outside of the box before you send it in.  You are not required to do so, but it does make shipping evidence easier on both you and the shipping company.

Improved 1 oz. Sample Container

Bonus feature!  Even though they look small, the one ounce jars will still fit your vampire or vacuum pump.  No need to purchase a new one!  Does your kit still contain the larger two ounce plastic jars?  That’s ok, too!  Just be careful not to fill past the “fill range” line imprinted on the jar near the top, and your evidence is well within compliance.  Don’t have a vacuum pump?  Call to order one from us.

Improved Sample Containers Fit Vamp Pump

We will respond as quickly as possible, and may be able to ship your kit the same day!

Organization of Scientific Area Committees (OSAC)

The National Institute of Standards and Technology (NIST) was created to coordinate development of a quality infrastructure for forensic science standards development.  There are about 20 people on the Standard Development Organization (SDO).  Some time later, NIST created a multi-level organization to conduct its assigned responsibilities.  This group is called the Organization of Scientific Area Committees (OSAC) for Forensic Science.  It consists of five Scientific Area Committees (SACs) which report to a Forensic Science Standards Board (FSSB).  Each of the five SACs oversee discipline-specific subcommittees.  Three Resource Committees provide input to the FSSB, SACs, and SAC Subcommittees.

Only about 550 of the world’s greatest experts on these topics are on these committees.  We are very proud to say that Dr. Andrew Armstrong is on the Fire Debris & Explosives Subcommittee of the Chemistry/Instrumental Analysis SAC.  Currently, OSAC is working diligently to improve old American Society of Testing and Materials (ASTM) Standards, and to create new standards.  These changes and additions are voted on by ASTM E30, Committee of Forensic Science.  Any changes are sent back to OSAC to vote on whether they accept, or reject the proposed changes.  Additionally, they are working on improving Quality Assurance/Quality Control guidelines, and on improving specific report language.

For more information about OSAC, NIST, any of the five SACs and their subcommittees, you may visit https://www.nist.gov/forensics/organization-scientific-area-committees-forensic-science.  There you will find more details about the improvement of these standards and guidelines that are based on sound scientific principles.  Stay tuned for the latest in this developing area!

Questions?  Feel free to contact us at (800) 644-4165 or (817) 275-2691 DFW Metro, or simply fill out the ‘Ask An Expert’ form on our website.  Dr. Armstrong, and his entire staff at AFLab is more than happy to take your call!

“Thank you Charllotte. I thoroughly enjoyed the presentation and it was nice to meet Dr. Wouters. The food was excellent and I liked the conference area.

Paint Transfer – Hit and Run

paint transferYou’re walking to your car, which is parked on side of the street in front of your house and you notice streaks of red paint transfer and a large dent on the body of your car.  You have been a victim of a hit and run accident.  Unfortunately, this type of incident happens quite often, and it can leave you, the innocent motorist, feeling very frustrated.  You are weary of filing a claim on your insurance because you’re afraid your premium will increase.  The next week, you are driving through your neighborhood and notice a red car, within close proximity to your home, that appears to have sustained similar paint transfer damage to their car, and you suspect they might be the culprit.  What do you do?

First thing you should do, if you haven’t already, is to call your local police department and file a hit and run claim.  The officers will come to the scene, take your statement, inspect yours and the suspect’s vehicle, and will file a report for you.  They may also be able to obtain the suspect vehicle’s insurance information by conducting a search in their vehicle registry database.  Be sure to write down the officer’s name, badge number, report number, and any other relevant information if the officer hasn’t already done so for you.  This information will become vital to your insurance claim, should you choose to file.

Next, contact your insurance company.  Let them know the situation, and give them every detail you have, including the information from the officers who arrived at the scene.  An investigator will likely come to the scene, with warranted permission, and collect forensic evidence from both vehicles.  DO NOT attempt to collect paint transfer samples on your own!  The process of collecting said evidence involves physically scraping the paint transfer off the vehicle using a scalpel or razor, and should only be conducted by trained professionals.   It is illegal to intentionally damage someone else’s property, so DO NOT attempt to do this on your own, or you will find yourself in a legal dispute as well.  Let your insurance company work for you!

The special investigator will collect three samples:  one from the insured vehicle, a second from the paint transfer, and a third from the suspected source.  Armstrong Forensic Laboratory provides paint transfer sample collection kits containing certified clean, unused tools to aid in the sample collection process.  The investigator will submit the three samples, and our highly trained analysts will compare the three samples, and can prove whether or not the red car in your neighborhood is the culprit.

Armstrong Forensic Laboratory is an American Society of Crime Laboratory Directors – Laboratory Accreditation Board (ASCLD-LAB) ISO 17025 accredited laboratory for paint and fibers; among many other designations.  This, in essence, means we are certified to conduct paint transfer analysis, and our reports can be used in civil or criminal litigation.  If you have been involved in an incident similar to the one described in the beginning of this post, please do not try to remedy the situation yourself.  There are plenty of trained professionals, namely those from your insurance company, who can, and will, assist you through this not-so-pleasant experience.

If you have any further questions about the process, call us at 817-275-2691, or simply fill out the ‘Ask An Expert’ form on our website, and someone will contact you shortly afterward.  Additionally, you can view the links below for more information and advice.
