Jack Froese died of heart arrhythmia in June 2011 at the age of 32 in the U.S. state of Pennsylvania. Perhaps his family and friends had not even finished mourning for his death when something unbelievable started happening with them.

Froese's family and friends claim that they started receiving emails from his account, post his death, and that has indeed brought happiness to his near and dear ones and helped them come to a closure, reports BBC.

What adds more mystery to the emails is that it addresses some really private incidents and conversations when no third person was present at the event.

Last November, five months after Froese's death, his childhood best friend Tim Hart received an email from Froese's account, says a blog in news.yahoo.com.

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 BBC. It was very quick and short but to a point that only Jack and I could relate on.

The subject of the email read: I'm Watching, and the short, to the point text read, Did you hear me? I'm at your house. Clean your f***ing attic!!!

According to Hart shortly before Froese's death, the duo had a private conversation in Hart's attic, and at this time, Froese had teased Hart for his messy attic. Just he and I up there. That's it, Hart said.

Jimmy Mcgraw, a cousin of Froese's, claims to have received a posthumous email warning McGraw 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.

Although the source of the emails is unknown as of now, Hart says that it's ok with him. Even if the mails are coming from someone who is playing a cruel joke hacking into Froese's account, Hart says he is taking things the way he wants.  

Similar instances have taken place before but those emails could be easily traced back to spam accounts which could access the deceased person's information.

Also, there are services available for people to send emails after their death, but this looks nothing like that.
