4. which computer files does the national integrated ballistics identification system (nibin) store?

Explanation:

1.

From the text, it says "Firearms databases can be searched to match crime - scene evidence to registered weapons". So investigators use firearms databases (like NIBIS, Drug - fire, NIBIN) to search and match ballistic crime - scene evidence to registered weapons.

The text states "National Integrated Bullet Identification System (NIBIS), which has computer files of ballistic markings of firearms used in previous crimes". So we get the answer from this sentence.

According to the text "Drug - fire, an FBI database that focuses on cartridge casings", so Drug - fire stores computer files related to cartridge casings.

Answer:

Investigators can match ballistic crime - scene evidence to registered weapons by searching firearms databases (such as the National Integrated Bullet Identification System (NIBIS), Drug - fire, and the National Integrated Ballistics Information Network (NIBIN)).
