There were probably two Hayners with the same name. I found a record of one in Boulder who turned out to be about 6 years older (around 38) than the man rumored to be the suspect (32). Looks like the killer was neither now.
That was correct - in 2015.
Most readers - including me the first time I read it - thought that article was written in 2021.
The only big contradictory fact that I could not explain was hair color.
Hayner's hair is brown or sandy red.
The fat guy in cuffs had black hair, black beard, and black chest hair.
It was hard to believe that Hayner would do such a massive hair dye job.
Anyway, I goofed, but I did enjoy doing the research.
