The black guy? Found face down in a shallow stream or something like that? I always thought delayed weirdness from a head injury, but I guess they'd have mentioned if he'd hit his head in the weeks leading up to his disappearance. My second choice would be "paraphrenia" or something else in the early-onset dementia realm. There was something weird about how fast he would have had to travel, but psychosis/mania is a hell of a drug.
nope the black guy is a different case. This one is David Glenn Lewis.
January 28, 1993: David’s wife Karen and their daughter leave Amarillo, Texas, for a shopping trip to Dallas.
David stays home, citing work obligations.
January 29–30, 1993: David is seen by friends and possibly a neighbor jogging near his home.
January 31, 1993 (Super Bowl Sunday):
David appears to have been at home:
VCR is recording the Super Bowl.
Two sandwiches are in the fridge.
Laundry is in the dryer.
His wedding ring and watch are on the counter.
February 1, 1993:
Karen and their daughter return home and find David missing.
She reports him missing.
That night (~10:30 p.m. PST), a pedestrian is hit and killed in Moxee, Washington (near Yakima) by a hit-and-run driver.
Had no ID.
Was wearing camouflage fatigues and work boots (not owned by David).
Was not wearing his glasses, which he needed to see.
Had no drugs or alcohol in his system.
David had traveled over 1,600 miles from Amarillo, TX to Moxee, WA.
Two airline tickets were purchased in his name:
Amarillo → Dallas (possibly Jan 31)
Los Angeles → Dallas (dated Feb 1)
It's unclear if either was used.
No one knows why David left home, where he went, or how he ended up in Washington.
The car was later found parked at Amarillo Airport.
The caller who found the body reported seeing a man walking, returned later, and found he had been struck — but has never been publicly identified.
