An unusual case of suicide by sharp force.

A 43-year-old woman was found dead inside the bathtub in a sitting position with a knife embedded in chest. Multiple sharp force wounds were present: 4 stab wounds in the sternal region, 2 cut wounds in the neck, several longitudinal and transverse cuts in the arms. Scene circumstances and autopsy findings pointed toward a suicidal etiology. The case presented some particular aspects that allowed us to identify the mechanism of production of the lethal thoracic wound and to partially reconstruct the time-sequence of injuries.
