Dismemberment refers, in general terms, to the act of cutting, tearing, pulling, wrenching or otherwise relieving the limbs from a living thing. It has been practiced upon human beings as a form of capital punishment, especially in connection with regicide, but can occur as a result of a traumatic accident, or in connection with murder, suicide, or cannibalism. As opposed to surgical amputation of the limbs, dismemberment is often fatal. In criminology, a distinction is made between offensive dismemberment, in which dismemberment is the primary objective of the dismemberer, and defensive dismemberment, in which the motivation is to destroy evidence.
