       There are numerous methods and locations for recovering firearm evi-

       dence. Guns can be found at shooting sites by crime scene investigators

       and transported to the lab. Typically, following adequate documentation

       or photography, each bullet, bullet fragment, cartridge case, shotshell
       wadding, etc., is collected separately and submitted to the lab. Obtaining

       bullet evidence in an emergency hospital setting is another option. In

       these situations, the material should be identified as a biohazard before

       being delivered to the lab. Each lab has written guidelines pertaining to

       the packing of evidence and its submission.

       Bullets and slugs that miss their target sometimes embed themselves in

       surrounding materials, such as a wall or wood.
       The easiest way to collect this evidence is to carefully cut out a bit of the

       substrate and submit it to the lab so that a weapon examiner can careful-

       ly extract it. This stops incorporating or eradicating any indications that

       might be essential for locating and matching the allegedly used firearm.

       When packing a firearm, the firearm may be recovered in the following

       conditions:

       •  Condition 1: Hammer down, safety on, empty chamber, no magazine
          in the weapon.

       •  Condition 2: Empty chamber, loaded magazine, hammer down, safety

          on.

       •  Condition 3: A chambered round, a full magazine, hammer down,

          and safety on.

       •  Condition 4: A chambered round, a loaded magazine, a cocked ham-

          mer, and safety engaged.

       The forensic experts in firearm examination study firearm features and
       ballistics to connect particular bullets or rounds to a particular firearm.
       From then, additional research aims to link the gun to a specific individ-
       ual. A serial number on a gun may frequently be erased.
