I bet all the hard drives have been destroyed.
Every single hardware recycler in the country keeps a written record of what they destroyed. Show me the lifecycle documentation showing the incoming serial number from the manufacturer, that that serials number was the same as the one in Lerner's computer, that she did not attach to email servers or POPped her email as opposed to Exchange or IMAP, and show me the recycling company's manifesto of serial numbers destroyed/recycled... then, I MIGHT believe you.
