Last November, five months after Froese's death, his childhood best friend Tim Hart received an email from Froese's account.
"One night in November, I was sitting on my couch, going through my emails on my phone and it popped up, 'sender: Jack Froese.' I turned ghost white when I read it," Hart told the BBC. "It was very quick and short but to a point that only Jack and I could relate on."
The email had the subject heading, "I'm Watching." While the text of the message itself read, "Did you hear me? I'm at your house. Clean your f***ing attic!!!"
Hart says that shortly before Froese's death, the two had a private conversation in Hart's attic, during which Froese teased him over the attic's messy state. "Just he and I up there. That's it," Hart said.
Froese's cousin Jimmy McGraw also claims to have received a posthumous email from Froese, warning him about an ankle injury that occurred after his cousin's death.
"I'd like to say Jack sent it, just because I look at it as he's gone, but he's still trying to connect with me. Trying to tell me to move along, to feel better," McGraw said.
For now, the source of the emails remains a mystery. But that's OK with Hart, who says that even if the emails are coming from a cruel prankster who has hacked Froese's account, he doesn't mind. "If somebody's joking around, I don't care because I take it whatever way I want," he said.
What's interesting and unique about this case is that the emails all had a personal touch. There have been several reported cases of emails sent from a deceased person's account, but those usually can be easily traced back to spam accounts that have accessed the deceased person's information.
Facebook has had somewhat similar problems for several years, with the social networking site sending automated notifications encouraging users to "reconnect" with the accounts of users who have died. Under normal circumstance, the feature is meant to help connect users who travel in similar social circles. In an 2010 New York Times story, Facebook said it was actively addressing how best to handle accounts belonging to users who have died.
