Someone in the earlier thread was asking about the mattress and box springs.
From what I recall the mattress was advertised to be given away for free on the Letgo site on either the 23rd or 24th of June. The box spring was advertised to be given away for free on a different site - the Facebook Salt Lake County Marketplace - on the 27th or so.
So both items were given away for free on two separate websites, several days apart. And yet when you look at the pictures in the listings, you can tell they were most likely taken at the same time.

Found Deceased - UT - MacKenzie "Kenzie" Lueck, 23, Salt Lake City, 17 June 2019 #7
JMO, but it seems clearly an attempt to get rid of evidence.
There was a tweet later on which said that SLCPD was no longer looking for those items, that they'd been located. Maybe someone else can track that down?
