Hackman was found in the mudroom and his wife in a bathroom. Mudrooms are usually designated for a secondary entrance, maybe from a garage rather than having one at the front door. So I'd to know which door was open, the front or the back door. I'm interested to know how they were both dressed. Two weeks prior on Feb 13 the temperature in Santa Fe had a high of 15 degrees F with a low of -3. The older you are the more you feel the cold. I wonder if he was anything like my dad who at a younger age would say, "Cold? Then put on a sweater." He didn't follow his own advice when he got older, though, the heating bills were crazy. So if the Hackmans had space heaters around the house, it must have been chilly yet when he was found he was only wearing a long sleeved t-shirt and sweatpants. The fact he had sunglasses on made me think that his going out was planned rather than hastily trying to go outside to find help for his wife. Unless his sunglasses were some kind of prescription lens. In the images of him and his wife outside a year earlier he didn't have any glasses on at all.
For me there's an elephant in the room when it comes to age and dementia. I know when my mom started showing signs of dementia my dad would make excuses for us coming to see them. Too busy, too cold, not the right time, etc. so they became fairly insulated. I had to bully my way into the house for him to relent. I find it odd that a 95 year old with obvious signs of physical decline had very little contact with the outside world and I wonder if his wife did what my dad did and tried to insulate her very famous husband's decline from public scrutiny even limiting his children visiting. This is all speculation on my part based on my own experiences. Whatever happened is pretty sad since they had been dead for a significant amount of time without any visitors, caretakers, or family.
