My first book was dedicated to the people who afforded me the opportunity to grow into the examiner I am today. This book is dedicated to those who push me to keep learning and allow me to share my knowledge – my students. Without you, I would not have had a reason to stay ahead of the curve, find those odd artifacts, and learn ways to outsmart the tools. You give me motivation to keep charging ahead. I would also like to thank metr0 for affording me opportunities to do things in my career that stretch far outside of what the norm is in forensics. I will be forever grateful.

To my husband, thank you for being such a great dad and for picking up the slack so that I can work as hard as I do. To Jack, always remember that your mama wants to be home with you and misses you while she's away. Remember that my work is important and teaching others the right way to conduct digital examinations may make your world a safer and better place. "The students" are happy you let them borrow your mommy. I would not be where I am today or able to travel and teach as much as I do without my amazing family and students.
