His testimony was devastating for the prosecutor's office, and is the reason for why he has now been fired. He testified:
That most likely lead prosecutor Berniede la Rionda had huge amounts of Trayvon Martin's cell phone data, probably already back in 2012, without telling the defence.
He was concerned that he might have criminal liability because the lead prosecutor appeared to be hiding from the defense exculpatory evidence.
That the lead prosecutor appeared to intentionally give Trayvon Martin's cell phone data to the defense in an unreadable format.
He was so concerned he sought legal advice and counsel.
That Zimmerman prosecutor Angela Corey's office policy regarding e-mail was not to put case names or ID information the the subject field, to intentionally make finding e-mails difficult and get around federal and state e-mail retention requirements.
Zimmerman prosecutor Angela Corey has now fired IT Director Ben Kruidbos.
