According to news reports, Gannon was located on 03/17/20. It appears that an autopsy was conducted within a day or two of his discovery, and concluded two things: 1) The remains were identified (with certainty) to be Gannon. 2) The manner of death was homicide.
Because CO authorities were immediately contacted, I wonder if "her" defense attorneys were notified, and LS was informed? If so; it's possible LS was aware of the discovery at least 24 hours before a public statement was released. The only thing I have to say about that: I hope LS has been pooping her pants for days. I also hope she was placed on suicide watch, had her clothes taken away, and has had severe diarrhea w/o the luxury of wearing underwear.
