Signo del cono truncado y signo de Benassi en suicidio por arma de fuego

the variability in the entrance and exit wound produced by firearms, depends on the distance, type of weapon and anatomical region, so it can present a very different morphology, which is the reason why, that although several pictures of suicide by other weapons have been published, today we provide a typical case of suicide by a short barrelled gun (pistol), concentrating on the description of the injuries that originate in the skull. here we present a case of a suicide with a 6.35 calibre gun. we intend to study the cone-like sign inside the entrance hole (incorrectly called bonnet sign) and the benassi sign.
