So just a couple of days ago there was this stupid bad accident down the street. Two LDS missionaries died right there. One survived. One was so dead they didn’t bother moving him 'til hours after the first fire trucks had left.
There’s orange spray paint all over the road where they died. My son asked me why yesterday.
Bad things happen, I guess.
In my area, they are big on painting crosses in the road where someone died. Once, a few years back when I was working nights, there was a wreck at the end of my long driveway in which someone was killed. When I got up in the afternoon, I saw the cross there. I slept thru the whole ordeal. Felt kinda creepy seeing it there. As far as your story goes, the paint will fade fairly quickly.
Investigatiog officers often mark locations of involved items, including tires and victims. They can use these for followup investigation.
That’s really sad, they were even wearing helmets and everything 
What makes it even more sad is that one of the missionaries who was killed was at the end of his mission. He had been scheduled to go home last week, but he chose to extend his mission for an extra 3 weeks to tie up some loose ends.
Earlier this year, an elderly man had some sort of medical event, lost control of his car and died in a one-car accident on the freeway. I got caught up in the traffic back-up, and when they opened up one lane the accident investigator was busy marking skid marks and so on with blue spray paint.
Months later, the spray paint is still clear and visible on the roadway. I keep wondering if the man’s family or friends are seeing this every day on their commutes, and how upsetting that must be.
I’ve not seen that around here yet, but I think I would be much more weirded out by paint all over the road than by the pathetic little crosses at the side, crowded with faded plastic flowers.
I understand the road-side crosses and memorials, but the official spray-painted reminder of someone’s final trajectory just seems sort of cold. He should have used water-based paint that washed away, or something, surely?
To the OP - that is indeed really sad, I hope the paint fades faster where you live.
