Wander00, I know what you mean.
Jaguar into a tree near Boulmer 1977. We were on site within an hour of impact, it was all still very ripe.
A truly horrible situation. I had to photograph the remains before they were bagged. We were at it for an hour before we were sure what we were dealing with. We found a rail saying "Rear Seat" & "Lossie" so we knew it was a Jaguar, then we found a second right hand, so knew both seats had been occupied.
Gathering evidence, treating the remains with dignity and staying calm. Balancing act.
Happy to never need to do that again.
