I've been wondering the same thing about trash pickup and maybe searching landfill.
Good point.
I think we are long overdue to have improved protocols regarding landfills when someone goes missing and the possibility of them being dumped in trash bins exists.
The landfill itself normally does a good job of recording specific areas and layers of trash by date, and they make trash trucks dump in specific areas so they are doing their part to generally know where each week's trash should be located.
But the amount of work involved in searching any section of landfill is very labor intensive and there is no guarantee they can even find a body even if we knew it was in a certain section.
Ever since LE searched a landfill and could not find Kelsey Berreth's body in her case, I have been trying to think of a way to identify if a body is in the trash at its source during the initial pickup at homes and businesses.
If there was a special sensor tool or something attached to the trash trucks and could scan the trash during pickup to identify if any human blood or human tissue exists in the trash, then it could at least be red flagged and at least be separated. Maybe new rules could be established that all the Trash pickup people need to do is to deposit that truck's load at a certain spot in the landfill which is different than all the other trash that does not set off the warning bell.
The problem is I dont think we have any scanning type device like that which could identify it. The device would have to work similar to Cadaver dogs and only set off an alarm when there is real human blood or human tissue detected. And of course with homeowners putting most trash in plastic trash bags then that could impede any type of sensor device.
So I cannot think of anything we have today that could even do something like that, short of something like a cadaver dog and that would not be feasible.
Maybe some day in the future technology could do something like this. It would have to be a simple type new process that doesnt adversely affect the trash collectors job much because they have hard enough time just getting to all the places they have to collect trash from. It would have to be some sort of automatic scanning that does not cause the trash collectors any more work other than dumping that trucks load in a different spot.
Its so frustrating to think that someone could have deposited a murder victim simply by throwing the body in the trash never to be found again. We have got to figure out a better way to prevent that from happening.
