Not my personal story but a one of my friend's. Back before her parents got married they lived in Washington state. This would have been in the late 80s. One day they decided to go out and go skeet shooting. They drove out to a fairly deserted place and parked out the side of the road. To get to the open field where they were going to shoot, they had to hike a little ways through a wooded area. They got out to the field and started shooting, but after awhile they got the feeling someone was watching them. They looked around the area and saw a man standing in the woods behind them, alone, staring at them. My friend's dad yelled out something along the lines of "Can I help you?", to which the man did nothing but continue to stare. After a few seconds he turned and walked back into the woods. At this point, my friend's parents, thoroughly creeped out, decided to leave. When they got back to where their car was parked, they saw a truck parked on the side of the road close to them, presumably the man's. There was a tarp over the bed of the truck. My friend's mom really wanted to look under the tarp because they had gotten such a creepy vibe off the man. My friend's dad convinced her not to and they drove away, writing all of this off to just a random, creepy thing. Flash forward years later, they're married now, watching the news. On comes a news program about the Green River Killer- the serial killer in the 80s and 90s in Washington who killed prostitutes, put them under a tarp in the back of his truck, and buried them along the Green River in Washington- the exact area where this man had watched my friend's parents a decade earlier. They firmly believe the Green River Killer had stumbled upon them while burying a body, fairly early in his killings.
