From OS's ... unsure of the spelling of his name though. Boles said in his testimony that 'an engineer would be able to answer that' to some questions from McGee, so hopefully he can.
We have a Vlad Jovanovic, who is our cell tower expert. We wanted somebody that knew cells, who knew cell networks. He has a Bachelor's of Science, Masters of Science, PhD in Electrical Engineering. He spent 35 years working in communication networks, 25 of that in cellular networks, where he optimized them. Checked them to see if they were working properly, developed them, tested them. He knows the towers and how they work and what they can tell you.
Elluma Discovery is for the computers.
Elluma doens't just handle computer discovery. They also work with cellular phone evidence. But they may only be working with the computer aspect of this case. I thought they might be involved with more, simply because their billing was for over a year.
