A number of details should be made of the firearm including its state when it was received, the type, the make, its serial number and the model among other important necessary details. If the firearm was either locked or cocked, this should be noted, and the number of cartridges left in its cylinder.

In this circumstance, as the identified firearm would be the main crime weapon, it would be necessary to test-fire it probably on a gelatine block to help get the test bullets and cartridge cases so that they can be compared with the items of evidence. The distance and directions travelled by the ejected cartridges should also be noted. This kind of testing should be carried out when the other tests have been done (Heard, 2013).

The major aim of doing such an investigation would be to help establish whether or not the firearm was responsible for firing the shots in question. Other key aspects that would help prove this would be the recovery of the spent ammunitions, the cartridge cases, gunshot residues and the study of the victims’ wound characteristics. This kind of evidence recovery would help in narrowing on the possibilities of the crime weapon used (Heard, 2013).

With a strong indicator pointing to the found firearm as having been used in the crime scene, it would be important to note other factors including its trigger pressure and if it is indeed working properly and that its safety features are in order. This to a larger part would help eliminate other potential defenses that could arise in such cases as suicidal crimes. In addition to these, other evidence including the gunshot residues and powder burns should be collected to help examiners determine shooting distances so that they could easily reconstruct the incident that occurred.
