PK was former FBI....and the remains were sent to Ft Worth. I'm seriously not putting anything into what has been reported so far...unless it can be backed up with other MSM. As far as The Examiner...if it's not Isabelle Z, then I take it with a great grain of salt. IMO.
JMO, it seems both articles are a way to satisfy and abate the curious...for some reason. Just like PK did. I'm not a ME by a long shot, but the authorities KNOW by now (if there were bones and teeth) more about this person. How tall he was, approx age within 10 yrs, approx weight, what previous injuries, ethnicity, how long the remains had been there, etc. The only things they would be waiting on would be toxicology and DNA. Were they able to get fingerprints...did they match anyone in system? Why is MSM not reporting anything at this point? (I'm still catching up...so..) LE's holding back for some reason...still..
IMO

PK appears to have a career as city manager in small rural towns, which makes me think that whatever he did at the FBI had little to do with investigation, and he was not too successfull at it. Otherwise you would think that he would be getting better jobs than that. He could have been a janitor for all we know.
