Ashley<3 asked:


What is the technical term for “jigsaw” crime evidence?
I don’t mean the figurative term, I am referring to when an item found at the scene matches up with a piece from the suspect. i.e. the tip of the suspect’s knife broke off in the victim’s wound, or a shard of broken glass from a hit-and-run victim matches up with the windshield and fits where it was broken.
Thanks in advance to anyone who can help
