Sorry to hear this Scott.

About ten years back my wife and I went to a county fair. By about noon she had a headache. We went home and she laid down for a nap. An hour or so later she got up and I took one look at her and hustled her into the car and to an ER just a mile and a half away. By the time I got her inside the building her she was so deep in shock they had to do a cut down to get a line in. With a couple doctors, me squeezing a bag of fluids in and a nurse on another bag, we got her stable. Two days in ICU and a day on the ward and I got her back. I was lucky. Sepsis can kill you so fast it's unreal, and the outcome far too often follows the route your FIL went. I've been trained. I live really close to a good ER. I still came within a blink. Don't let them beat themselves up. Just a tiny count of minutes and I'd have lost her. Just waiting for an ambulance would have killed her.
