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?

Fingerprints, manufacturer information, and make/model

Explanation:

The glass recovered can be used to identify the make and model of the car, manufacturer information, and if they're lucky, fingerprints. Different companies whom make cars use different materials. Corvette glass is very fragile and is known to completely shatter on impact whereas a Jeep Wrangler with gorilla glass is going to be a lot more different in materials, and probably not going to shatter the same way (if at all) either.
