I highly recommend Chrystal Waltz of Berry-Waltz Investigations (BWI) and Kyne Marshall of Digital Forensics Expertise and Technology (d/FEAT) for their help on my recent federal bank robbery case. Kyne analyzed spy tech devices and pinpointed cell phone locations. Chrystal did the fact investigation and helped me during trial, pinpointing issues that helped our defense. BWI and d/FEAT’s work is excellent.
