(Q&A with Moscow neighbor)
(KTVB video day after the murders)
I believe the Elantra tip could be a red herring offered up by someone to sway the investigation in a different direction.
In the KTVB video a white, possible Elantra is seen driving down the street behind the reporter. In the video it is also stated, erroneously, one of the victims is from Arizona. (It was corrected later to state all victims were from Idaho.)
In the Q&A, which was conducted AFTER the KTVB segment, the subject says he saw a white Elantra and he also spotted a license plate in the parking complex from Arizona, or he said maybe it was Montana or Colorado.
In my opinion only, he is injecting himself into the investigation and repeating information that he gleaned from other sources and never personally saw.
The white vehicle lead must still be followed up though, if only for it to be eliminated, if need be.
