Suicide by loop knot strangulation. Presentation of an atypical case

Abstract

In Legal Medicine specialists find everyday dead people whose direct cause of death is mechanical asphyxia by neck constriction produced by the halter used in each case. Cervical constriction may be caused by hanging or by hand or loop knot strangulation. This time we presented the case of an elder woman aged 69 years who, according to data brought by police instruction, was found home presenting, as a violence sign, a slightly deep horizontal line in the neck, 3 cm width in its back part, with soft surface, directed from the back to the front, interrupted in the neck frontal part, in correspondence with the knot position. She had antecedents of psychiatric disturbances, justifying her behavior; she was an individual unable to adopt life norms fitting the socio-cultural environment where she used to live, frequently showing tendencies to depression.
