Jack Froese's sudden death last year at the age of 32 shocked his friends and family in Dunmore, Penn., but not as much as the emails mysteriously sent from his account since then.
Froese died of a heart arrhythmia in June 2011, but nearly six months later in November, some of his closest pals like childhood friend Tim Hart and cousin Jimmy McGraw received mysterious emails from his account, according to the BBC.
Even stranger: The messages were about things Froese discussed with his friends in their last conversations, such as the message Hart received with the subject heading "I'm watching."
The text of the message itself read, "Did you hear me? I'm at your house. Clean your f--ing attic!!!" YahooNews reported.
"I turned ghost white when I read it. It was very quick and short but to a point that only Jack and I could relate on," Hart told the BBC, adding that shortly before Froese's death, he privately teased Hart about the attic's messy state.
Hart later sent a reply to the account, but has yet to get a response.
McGraw also 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 told the BBC.
Froese's mother, Patty, told the men just to accept the mysterious emails as a gift, the New York Daily News reported.
"I saw they made people happy, they upset some people," she said. "But I see it as people were still talking about him."
Although the source of the emails is unknown, Hart doesn't mind, even if it turns out he was the victim of a cruel prank.
"If somebody's joking around, I don't care because I take it whatever way I want," he said.
