With ransom time passing, imo, something tragic happened to NG and this was not a kidnapping, but a coverup to conceal the tragic event. I believe NG would need more than 2 minutes to be properly dropped off at around 9:47, and I see the 9:47 or so garage time as a quick in and out to leave NG purse and phone. I think NG may have come home a different time, but not the garage open and close time. I still see this as an intimate, someone NG knew and trusted encounter. Like at 84 years of age, one would assume she did not live alone at night, especially being in constant pain, having heart condition, and requiring walker or other assistance for mobility. Someone who did this to NG was close to her imo and knew her routine, habits, and care team. I think the ransom letters were all fake and not related to the crime. 40 mins of activity starting around 1:30am also seems staged. I also think NG could have had like a nosebleed at exterior front entryway a different time than say 9:30pm to 2:30am. Like maybe she bled even on a different day and just did not clean it up. I hope she is found alive and safe but to me it's unlikely.
