What is your job?

I am the Evidence Room Manager for the Killeen Police Department in Texas. In addition to managing a team of Evidence Technicians, I ensure proper collection, analysis and storage of evidence for the department. One of the most common forms of analysis completed by the evidence lab is dusting for latent fingerprints, which can help identify suspects.

Why did you choose this field?

I think it chose me. I always knew I wanted to go into law enforcement and I served as a police officer for many years. Later I discovered a new interest while working a homicide case. While collecting and analyzing evidence from that crime scene I realized I was intrigued by the science behind all of it.

Explain what an average day at work is like for you.

I wear several hats, but evidence is always my main priority. Every time evidence is collected from a crime scene I oversee the team that ensures it is stored properly at the Killeen Police Department. A lot of evidence has to be refrigerated or even frozen to be preserved, so we have to take every precaution necessary to ensure it is not contaminated. Before the evidence can be stored, my team has to process and analyze it. Some of the analysis techniques include DNA extraction. Each day is different, but one thing remains constant - there is always evidence coming into our evidence room.

What do you like best about your job?

I definitely like the forensic science and new technology behind evidence analysis. There is nothing like finding something that has been overlooked by everyone else. Discovering the piece of the puzzle that cracks a case wide open is the ultimate high.

When you were a kid, did you like science, engineering and/or math? If so, what subject did you enjoy most and why? If not, what changed your mind?

I never thought I liked STEM subjects as a kid - instead I was more of a history buff. Looking back on itimage though, I guess I've always had an interest in engineering. I didn't realize that all the tinkering I did as a kid was engineering. I still tinker - put things together, take them apart and re-purpose them. I'm also still really interested in history - civil war in particular.

Was there a moment when you knew that you wanted to go into law enforcement? Tell us about it.

There was not a moment I can pinpoint, but as long as I can remember I thought I would become a police officer. My mom worked for a police department, and I was a Law Enforcement Explorer with Killeen department. This was a great experience for me, and it reconfirmed what I kind of already knew - that I was suited for public service.

What was the biggest challenge you faced in your journey to becoming an Evidence Room Manager?

The education requirements are the biggest challenge. I have an Associate Degree in Law Enforcement and am close to retirement at this point, but these days the evidence technicians and forensic scientists that complete analysis on crime scene evidence have at least a Bachelor's degree, but most have a Master's or even Ph. D. I transitioned from being cop to the evidence room right when the field was changing and we were starting to use more science and technology to collect and process evidence. I do a lot of training classes and feel secure with my abilities, but technology and science are always changing. If you want to move into this field, you need to be prepared for a lifetime of learning.

What inspired or convinced you to get involved in your field?

I had several inspirations throughout my life. Being around officers as a kid really inspired me to go into law enforcement, but my transition over to evidence can be attributed to Texas Ranger, John Aycock. As a cop, I worked several crime scenes with him and he seemed impressed with my abilities. He mentored me and introduced me to a lot of important people in the evidence field, which ultimately provided me with the opportunity to move into the evidence room.

Introduction to Your Field: Do you have any suggestions for how kids in high school can get practical experience in your field?

The Law Enforcement Explorer program is a great way to gain exposure to this field. Also, check out summer camps in your area that focus on science or technology.

What majors in college would you recommend for a student who is interested in a similar career?

Studying criminal justice or taking criminal lab science courses would all be helpful.

The Future of Your Field: Are there exciting things happening in your field that could involve young adults who will enter the field in 5 years?

When I first started working with evidence, we did not have DNA analysis - science has changed so much since then, and it is difficult to predict where we will be in 10-15 years. We are relying a lot more on computer scientists when processing the evidence because technology is everywhere and used by everyone now - even criminals. Our tech guys analyze computers collected during crime scene searches and smart phone activity is being scrutinized more than ever before.

Fast Facts:

 

  • Fingerprints are classified into 3 main categories - Loop, Arch and Whorl. There is also the 4th Accidental category.
  • Fingerprints are more unique than DNA because not even identical twins have the same print.
  • Science has become so sophisticated that DNA can be extracted from many fibers found at a crime scene, not just blood.
  • DNA is a fairly recent tool used in Crime Scene Investigations. In fact, the first time DNA evidence was used to get a conviction in the US was 1987.

Lab Lingo:

 

DNA - (deoxyribonucleic acid) and it provides genetic instructions for all living things.
Latent Fingerprints - term used in forensics to describe fingerprint marks left at a crime scene. A latent finger print may not be visible to the naked eye
Fingerprint Dusting - Method used to collect latent fingerprints that involves applying an ink colored dust to the area until it highlights fingerprints
DNA Extraction - the process of removing deoxyribonucleic acid (DNA) from the body cells
