LIDAR Shown to Be a Powerful New Tool in The Hunt For Missing Murder Victims
Unmarked graves, such as those in which murder victims are often callously concealed, may soon be easier to locate, thanks to a technique demonstrated by US researchers.
They have found that LIDAR, a tool proving increasingly useful in archaeology, can also be applied to forensics.

Nice. Not sure exactly what “elevation change” means in this context. Does it mean they have to image the site before burial?
yes they did
“For the immediate study area, including human graves, the control plot, and undisturbed surfaces, we derived our final data products by subtracting a later elevation image from an earlier elevation image. Each of the post-burial elevation images was subtracted from the pre-burial image, and the same operation was performed for each logical post-burial image pair, for a total of six elevation change images”
