Where’s Computer #35?

Last November, legal professionals for the plaintiffs asked for the forensic pics of the 35 computers. However, Premera ought to most effectively provide pics for 34, pronouncing the 35th were destroyed, the motion says.

The movement alleges that Premera “willfully” destroyed A23567-D. According to Premera’s discovery filings as quoted inside the movement, its destruction appears to have been a mistake.

While Mandiant sequestered the opposite 34 computer systems, A23567-D was “by accident filed as the end of life,” Premera contended. It remained unused and offline for 12 months within Premera’s Client Technology Services.

The plaintiffs see that as large trouble in their case whilst going to trial.
