An accident investigator arrives at the scene of a hit-
and-run collision. The driver who remained at the scene
reports that the windshield or a side window of the car
that struck him shattered on impact. The investigator
searches the accident site and collects a large number of
fragments of tempered glass. This is the only type of
glass recovered from the scene. How can the glass evi-
dence help the investigator locate the vehicle that fled
the scene?
