My hearts and prayers go out to MC's acquaintances, friends, and family. No one can truly measure loss except by the hole left in one's absence.
As unique as our fingerprints, we all grieve in our own way. Let us not pass judgement on ANY of her family, immediate or extended thru relationships, in ANY way - innocent until proven guilty. More so, these people are in DEEP grief and by jabbing at them in their pain, is horrible to watch.
That being said... I am curious as to why LE has not asked if anyone saw someone walking out of NUMBER TWO canyon in the wee hours of the night or morning following the found car. It seems to me that the person(s) who committed this crime is from the local area. IF it was me not wanting to get caught - I would NOT walk out Pitcher Canyon, instead I'd walk down the road away from the car (ie footprints) and THEN hike over to Number Two Canyon Road and down into town that way, or possibly via Saddlerock.
