Earlier this month Dallas County District Attorney John Crezot said about 14 terabytes of data were recovered, but eight terabytes were thought to be unrecoverable. That's not including the 15 terabytes announced missing Monday.
The deleted files were believed to be data archived before July 2020. The city said they are still unsure what data exactly is gone for good. Lawyers said the lost data could jeopardize court cases.
Dallas Chief of Police Eddie Garcia said violent crime files were not affected.
