I don't think anyone is describing the situation correctly. When she was reported missing, MPD likely went to her apartment to investigate and collect anything that could have information about her disappearance. Once they officially clear the area ie. determine it is not a crime scene, it goes back to being a regular residence. At that point, if her landlord isn't receiving rent, they start a civil eviction proceeding for non-payment. Once the eviction is granted, the sheriff's office does what's called a "put out" and they remove the person's belongings from the house and literally put them out on the curb. LE will warn you beforehand and ask you to move your stuff out, but if you are missing, you obviously can't do that.
I am just surprised and sad that no one thought to pay the few hundred dollars for her rent to preserve her home for evidence when a suspect is eventually caught and charged. Think of how much potential evidence has been spoiled. No PI is going to get back a suspect's hair or clothes on Danniella's bed to disprove the suspect saying he "wasn't friends with her" or didn't know her. What a shame. I can't imagine anyone associated professionally with missing persons cases would recommend this course of action.
