62% Yes 38% No
Reasons: They are not aware of what we can do They are not familiar with collection techniques
and what to collect Collection is time consuming

“Trace requests make up less than one percent of the total cases.”
“Authorities say cases usually are not solved on trace evidence alone.”
![Page 15: The Current State of Affairs and Trends in the Crime Laboratories North Carolina State Bureau of Investigation Deputy Assistant Director of the Crime Laboratory.](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649e315503460f94b22341/html5/thumbnails/15.jpg)
“More than $500,000 in new equipment would be needed to continue the trace program.”
“Is it wise to the tax payers of the state to continue with this when we have rapes, murders, and burglaries that can be solved by DNA?”

The Curse of NumbersCases vs. Items
“All administrators want is numbers”
“Many trace analysts are notoriously slow”

City and county laboratories are often under the control of Law Enforcement. The agency head may be a sheriff or police chief who may not be fully aware of the needs of the forensic laboratory.

“Current lab management has not grown out of Trace units, and has little or no appreciation for the value of, and necessity for, well equipped and well trained Trace units.”
“I have always loved trace evidence – I have tried to convey to the lab administration the importance of hiring another Trace Analyst before I retire so that person can benefit from my experientially-gained knowledge.
Sadly, they don’t care.”

Statistics:
“The Tyranny of Numbers”
‘If statistics are to be applied to trace evidence they must be applied in a way appropriate to the discipline, unbiased in interpretations and accessible to the trier of fact.”
-- Max Houck

** 62% of labs reported that Trace Evidence has diminished in the eyes of law enforcement!
The Future of Trace Evidence:Raising Awareness – Advertising!

Trace Evidence should be viewed as a complimentary aspect of evidence analysis – it shouldn’t be regarded as “last resort evidence.”
Final Thought…
