I do not know the answer to that. Maybe those witnesses were mistaken about dates. Maybe Taylor drove back clandestinely and only went to Cali to give himself an alibi and the murders took place after the 28th. 
What I know is that he was a career criminal (drug dealing, check fraud, rape), that there are no other suspects (or anybody else with motive) and that even his brother and his ex initially said Taylor did it. Moreover, even the "progressive" St. Louis DA Wesley Bell refused to reopen the case - if there was a reasonable chance of exoneration, don't you think he'd have done so?
Your last comment is more interesting. How slim a chance? And is locking up somebody for the rest of their life really that much better if "slim chance" is actually true?
We're talking about Missouri here; I doubt they'd stop the execution even if he was proven innocent beyond any possible doubt. >

Well, according to SCOTUS a state’s interest in finality of outcomes trumps a person’s interest in not being unjustly railroaded and killed by their own government. Like literally that’s current law now.

I'm painfully aware that innocence is not a legal defense or grounds for a new trial in the US, I was just pointing out that there wouldn't be any kind of gubernatorial pardon coming out of Missouri even if he was proven innocent on live, national television. >

Fair enough, a live show proving his innocence beyond a shadow of a doubt would probably cause a MAGA governor to accelerate his execution to own the libs. >

Both disgusting and accurate. What a sad fucking country we live in. >

That fuckwit Parson won't do it.  He is even more of an asshole than Greitens if that's possible.  Just way more sneaky. >

The fuckwit here is Raheem Taylor, who murdered four people, including three children. 
Why does he deserve clemency? >

Except that multiple witnesses—including relatives of the victims—have said (at least one under penalty of perjury) that they saw the victims alive after Taylor had left the state.
But, even if we discount the sworn statement of the accused’s daughter—and the statements by the victims’ relatives and neighbor—the larger question is not whether or not Taylor “deserves” clemency, but whether or not we deserve to live in a society that would be willing to kill him (particularly—but not exclusively—when there’s even a slim chance he didn’t do it).
