Well that was simple enough, no? Just ask the source directly when you doubt their accuracy. Whoever DID decide to contact Nate had perfect timing. If what Nate said is true and he did JUST yesterday speak to the sheriff who then set the story straight, it's hard to tell how an earlier inquiry would have been answered.
I AM now and will continue to be amazed how so-called journalists publish so much incorrect information. In this case Nate had NO source whatsoever who provided him the information he published as "fact", so he can't even say he got it wrong. He didn't misunderstand; he didn't through inadvertence mis-speak; and he didn't mis-quote anyone. He simply had NO idea and didn't care enough to find out. That's not sloppy work, it's SHODDY work.
