This article reports the results of analysis of  the data borrowed from the special literature. They demonstrate the  absence of objective forensic medical evidence needed to diagnose injuries to the human body and  clothes inflicted by the darts fired from the pneumatic rifles. Meanwhile, the use of the darts differing in the design parameters has the significant influence on  the morphological features of the resulting injuries. The knowledge of the  dart characteristics creates the prerequisites for the differentiation between the injuries caused by these missile weapons and other metallic objects.
