Apparently you have NOT been paying attention. Edmunds never was a suspect to begin with. But since his car was traced to the location near the time of the crime, and given his checkered past, it seemed logical to seek him for questioning.
That's what the police did; they QUESTIONED him. In response to questioning he gave them "very valuable information" that they are following up as we speak.
Who knows what his tie-in to the crime might be? But at least he proved to be more than a dead-end as you seemed to imply.
I hope that's a bit more clear for you.
It was clear to me from the beginning, but thank you anyway, sincerely, for the explanation. I hope you're a bit calmer today so we can discuss in a more reserved manner.
