Testimonials

 "I recently had the privilege of utilizing Mark Johnson in a homicide
trial.  His cell phone analysis was crucial for securing a conviction
for murder.  Mr. Johnson has not only a tremendous command of all the
technical subject matter used in his analysis, but the unique ability
to convey complex subjects to jurors.  His analysis not only placed
the defendant in the exact parking space the murder occurred in at the
time of the murder, but he was also able to perform further last-
minute analysis which showed the defendant accessing social media
photos of the victim and witness days after the homicide.  Mr. Johnson
eagerly and readily handled all last minute requests in a highly
professional matter and provided the raw data we needed to create
trial exhibits.  One could not ask for a better expert witness than
Mark Johnson."
