Powder burn
Powder burns were types of burns cause by chemically propelled weapons that left residual combustion products on clothing or skin. Constable Odo noted the lack of powder burns on the body of Hector Ilario, despite his being killed by a bullet. Doctor Julian Bashir was unfamiliar with the term – Odo knew it from 20th century crime novels he read. The absence of these markers was eventually found to be due to the fact that the shooter, Chu'lak, used a micro-transporter attached to a TR-116 rifle to beam the bullet into the room where the victim was while he stood elsewhere.
