Complex suicide: an unusual case with six methods applied

Area of Science:

• Forensic Pathology
• Toxicology
• Psychiatry

Background:

• Complex suicides (CSs), involving multiple methods, constitute 1.5-5% of all suicides.
• Understanding the methods and contributing factors in CSs is crucial for forensic investigation and public health.
• This case presents a unique instance of extreme self-harm behaviors.

Observation:

• A 44-year-old man was found deceased in a deserted, frozen field.
• Autopsy revealed wrist and neck cuts, gastrointestinal acid burns, hypothermia, insecticide ingestion, and multiple screwdriver stab wounds to the head.
• Police investigation ruled out homicide, and no prior mental health diagnoses were confirmed.

Findings:

• The cause of death was determined to be stab wounds to the head inflicted by a screwdriver.
• External hemorrhage and hypothermia were identified as contributing factors.
• Toxicology confirmed insecticide ingestion, adding to the six methods used in this complex suicide.

Implications:

• This case represents the first documented instance of six distinct methods being used in a complex suicide.
• The use of a screwdriver for fatal cranial stab wounds is an exceptionally rare suicidal method.
• Such extreme cases underscore the need for comprehensive forensic analysis and mental health awareness.
