bbm I think that's a relatively smallish field given the vastness of the area. It tells me they're mainly searching for more bones, and / or hoping to discover identifying discards or possibly other crime scenes. I do not believe they're specifically looking for a 'killing field' but may be attempting to rule it out. There's been no mention of what was initially recovered, such as bones, clothing or shoes but we may safely assume one or more bones were located because the FBI was able to extract and confirm DNA.. I doubt usable DNA would survive on extreme-weather-exposed clothing for very long. Ls LE searching for items that might connect the crime scene to what LE found in other searches? The following article is from February 15, 2012. I had forgotten what LE discovered while executing search warrants of the 'town jeweler'... a partial list is provided in the article (bbm): The link to the article is no longer valid: I am not sure if the jeweler was able to provide explanations for those items but after all these years it's likely the items were unrelated to this case. He's proclaimed his innocence since then, and I believe him. I include this post only for reference.
