A chilling romance

I met a guy online. We emailed and messaged (this was before texting was a thing) and went out a few times. I liked him but wasn’t sure about it. He called me pretty regularly (again, this was pre-texting). One day, no calls. That night I called and left him a message. No return call. I called his work the next day, and he hadn’t shown up. I called the police, who did a well-person check at his house but he wasn’t there. I wasn’t there. The next day the police called me back — they’d found his body. He’d been murdered by one of his neighbors and I had to testify at the trial.
