My favorite answer from a previous thread:
Credit where credit is due. /u/rwbingham
It was near Halloween time when my friends and I were telling ghost stories. My friend said she was going to tell a story about her parents' first date. She said she didn't like telling the story, since it was actually true, but we prodded her on.
To cut to the chase, the parents had spent a nice, if awkward first date, and around the time that they would have said "good night," the male in the situation--my friend's dad--suggested that they go for a midnight hike up Provo Canyon. He apparently knew the place, since he had done a fair amount of rock climbing in the area. So the two drove up the mouth of the canyon, got out of their cars and started hiking under just the light of the stars, since it was a new moon.
At some point, the male starts getting a "bad feeling," since the pathway ahead, which would pass under some trees, would be dark, and because it was getting to be quite late. He ignores the feeling and presses on. In later rehearsings of the story, the female would say that she had felt the same feeling at what was probably the same time, though she didn't know the trail like he did. A minute later, the feeling came back to the male. He ignored it again, and started walking a bit of the way into the trees when his foot hit something "soft" in the middle of the path. Under the trees, it was too dark to see just what this soft thing was, and the feeling came back stronger than ever. Instead of finding out what his foot had bumped into, he and the female both agreed to hightail it out of there...
Years later, after being married for some time, they were watching an interview with the serial killer, Ted Bundy. In response to a question asking him to describe the time that he felt the closest to being caught, he explained about the night that he lured a girl into Provo Canyon, and had just killed her when he heard some people coming up the trail. He explained how he hid in the trees just in time, only to watch some guy walk right into the body, and for some reason, just turn around and walk away.
TL;DR. Friend's parents stumbled onto a fresh corpse left by Ted Bundy on their first date.
