I haven't followed nearly as many cases as some of the more seasoned posters here. If others with more experience than me say that LE rarely names a POI or suspect until they make an arrest, then I defer to their knowledge. My understanding is that the term "suspect" is a legal term, and once someone is named a suspect, it sets into motion a time frame regarding charges being brought against the accused.
Whomever is responsible, LE needs solid proof.
At this point, if all LE has regarding their investigation of TH is what we've read/heard about in the media (cell phone pings, showing deception on a key answer on a poly, unsubstantiated MFH plot) that's not even enough to convene a Grand Jury, let alone bring charges & pursue a conviction.
In terms of the idea that LE may be naming TH a POI or suspect through KH & DY, here is the official stance of the MCSO:
There will be no comment from the Multnomah County Sheriff's Office regarding the information reported during the Horman/Young July 8, 2010 press conferences. The information released in during these conferences did NOT come from the Multnomah County Sheriff's Office. This is an ongoing investigation.
