This keeps being asked by myself as well as others, yet I've not seen it answered (or even simply discussed) in media, by LE, or by Kenzie's friends in their interviews or by our VI.
What made alarm bells not go off Monday, Tuesday, Wednesday or Thursday morning when MacKenzie was not around and not heard from?
There is a lot of overlapping not only in relation to the ways that people know MacKenzie but in relation to one another as well.
This isn't a case of "people at school noticed she wasn't in class and her social friends noticed she was unreachable by phone but neither parties overlap, so social friends didn't know she also wasnt in class and classmates didn't know her friends were unable to reach her by phone as well.
Some people know MacKenzie via at LEAST 3 different realms of life: School, Sorority AND friendship. I imagine there is also some additional possible overlapping with colleagues and/or roommates.
But no one local reported to Campus Police or SLC PD. There has to be a reason for this. Had she had a 3 day unexpected "off the radar" break in the past. Were friends she reportedly had daily contact with unaware of what day she was supposed to fly back? Were friends afraid a missing persons report may be overreacting or jumping the gun for some reason? Did she have set or loose posdible plans to go away after the funeral but was supposed to be back Wed night/Thurs morning?
Was there something about MacKenzie's life or actions the days/weeks prior that lead people to the conclusion that this wasn't actually surprising or as out of character for her as claimed?
ETA: In one interview, (I believe it was her BFF and sorority sister?) She commented that she reached out to MacKenzie offering support or to see if she needed anything over the weekend, while she was still out of state for the funeral. She received no reply. Yet MacKenzie was active on social media during that time? Is that odd: she already wasn't responding to her BFF prior to her disappearance, but was active on social media?
