Well, I'm kinda late to the convo...
But it's true about suicidal folk putting things in order.
A friend of mine used to work for a medical examiner's office in Florida a number of years ago.
We spent the better part of a Saturday talking about his experiences and such. He dug out his old files, photos, and slides of cases he worked and showed them to me.
A great number of the suicides he investigated involved people that had planned for it and the aftermath very carefully.
One that struck me in particular...
An older gentleman living alone, a WWII veteran, shot himself. He laid out all of his important papers, bills & such, left notes on what to do with each, and finally a detailed letter of why he chose to commit suicide.
He even went so far as to detail exactly why & how he did the deed.
He committed the act in his garage; for two reasons. First, so he didn't make a mess in the living area, hoping that someone might find use of the house later on. And second, because of the way it was built. It so happened the floor of the garage was laid on a slight incline and any liquids that found their way into the garage would flow down the incline and out through the roll-up door opening.
He picked a spot close to the door, laid down with his wartime bring-back Colt Gov't 1911, and shot himself in the head.
As he'd planned, the blood from the wound slowly ran down the incline and out the doorway He had opened the roll-up door just slightly to allow the blood to flow out to the driveway where it would eventually be found...
Which it was. I don't recall exactly who found it. Was a neighbor or service worker I believe, but his plan had worked perfectly.
I don't often get emotional about much of anything but I was pretty damn choked up after hearing the story and seeing the photos.
