Several of us re-posted that article (because it was so amazing!), but
I believe the first to bring it to this forum was Wondergirl. It is an emotional story. Lots of parallels to this case. Heartbreaking.
In addition to re-posting that article, I re-posted a podcast by Jerri Williams, an ex FBI agent turned crime writer. It's an interview Eddie Freyer, the head FBI agent in charge of Polly Klaas abduction murder. (I'm sorry, but I don't recall who posted the reference to the podcasts.)
Polly Klaas age 12 was abducted from her California home on Oct. 1, 1993. Her assailant was not apprehended until 6 months later after an exhaustive, highly publicized investigation. He led authorities to her body after the arrest. Huge media coverage. Large reward. Massive amount of tips called in. (Sound familiar?) He was convicted of the crime and is still on death row in California, going through appeals.

This is a 2-part report, each podcast runs about 1.25 hrs. Very interesting. Very detailed info about the investigation. I think the emotions of the LEO's as described by FBI agent Freyer during this investigation probably are very similar to what LE is experiencing here now. I highly recommend giving this a listen.
