Topic: Distance Determination Information Needed

[Kimberly James]

Hi All,
I am in need of some feedback and would appreciate any info you would be willing to share.


1.) Is your lab ACCREDITED via ANAB for distance determination? If yes...
2.) What measurement process do you use such as (laser, tape measure, or other)
3.) Did you run our own stats and complete the Uncertainty Budget in-house or did you hire someone?


If this is better posted as a Poll, happy to do so.


Many thanks,
Kim James

Yes (ANAB Accredited), we did uncertainty of measurement using a tape measure and completed the stats in-house.

[Loandra Pellot-Vazquez]

ANAB accredited, we use a laser for measurements, and the uncertainty of measurement was completed in-house.

[Justine Kreso]

ANAB accredited, laser, and in-house UM.  The stats aren't too difficult and you can use the same template that you do for barrel/overall length.

For SWIFS in Dallas County:

• Yes ANAB Accredited
• Leica Laser with a panel that the muzzle of the gun goes through to allow for measuring off to the side of the firearm
• U of M was done in-house

[Julie Knapp]

same with Richard for Colorado Bureau of Investigation.

[Russ Karsten]

Same as Julie for labs within the Michigan State Police.

[Steve Ostrowski]

We are not ANAB accredited in GSR/DD.  We chose to remove it from our scope 2 cycles ago.  However, we still perform the traditional work. 

We issue standard lab reports but on alternate letterhead without ANAB logo.  We also add this disclaimer to report verbiage:  "Please note, gunshot residue examinations are not covered under the Forensic Laboratory’s scope of accreditation."

Thank you all for the replies.  Happy to see more if others are willing.


I appreciate the speedy information.

Here in RI same as Steve

[Emily Bagwell]

[Dan Alessio]

ANAB accredited.  Laser (Leica DISTO X3).  UM in-house.

Hi Again,
If anyone would be willing to send your U of M worksheet or data sheets for the process used for determining your uncertainty for use with a laser, it would be greatly appreciated. It is a big ask[size=78%].[/size]


Before our QM signs off on our planned process she wants to see what others did. 


If you would rather not post it here, please email me.
