Start up with Sylvester Stallone
Our next witness is Ron Schnell. He is a social media forensic expert. He says he's a director at Berkeley Research Group.
He tells us there was a lot of press about him as a youngster, as he was a professor when he was just 14. He says for that reason he "
skipped" an undergraduate course, and went straight on to work, describing it as being "
lured away".
He tells us he has also worked at other places including IBM and Bell, as well as several of his own start-up companies, including one called Secure Online Systems, which he set up with actor Sylvester Stallone. He says it is now shut down.
He currently consults, manages software projects at Bell, gives expert testimony at cases like this, lectures in computer science and has also published several papers.
He will first be questioned by Johnny Depp's legal team.
