Except for hair color, the guy led away in handcuffs looks almost exactly like the guy who threatened to kill the Denver District Attorney five years ago.
Plus, he has (or had) a P.O. Box or a shelter address one mile from the shooting.
Plus, his Facebook account was completely deleted several hours AFTER people began to speculate it might be him.
Since Thomas Elliot Hayner has not publicly stepped forward to defend his good name, and since the Police refuse to identify the man in cuffs, I think speculation by the general public is understandable and necessary.
Probably to protect his name? He did not do it. It is a crazed muslim.
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.
