Just generally depends upon what an agency's procedures are concerning this kind of situation. My best guess is that most PD's will generally help with securing someone's property in most cases. Usually it will likely be logged into the property room for safekeeping or maybe turned over to a friend or relative at the scene if it is not some form of evidence.
I don't wish to take sides on the issue but I am a little confused as to why the victim's "stuff" was left on the side of the road? But again, perhaps there is some sort of explanation that would shed light on this if we had the opportunity to ask some official that was there? The only other thing that comes to mind is maybe someone forgot to gather the victim's things and accidently left it there? Who knows at this point.....that's my thoughts on this.
