Pentobarbital overdose: A case of contract killing

Area of Science:

• Forensic Toxicology
• Neurology
• Sociology

Background:

• Suicides involving pentobarbital overdose have notably increased since approximately 2012.
• This rise is potentially linked to the dissemination of technical information regarding active euthanasia via the internet.

Observation:

• A case involving a patient diagnosed with amyotrophic lateral sclerosis (ALS) presented with pentobarbital poisoning.
• The patient was discovered unconscious by a caregiver shortly after two visitors departed.
• Despite immediate transfer to an emergency hospital, the patient was pronounced deceased.

Findings:

• Fatal concentrations of pentobarbital were confirmed in blood samples from both the emergency hospital and autopsy.
• Analysis indicated pentobarbital was likely administered through a gastrostomy tube, supported by high ratios of pentobarbital in gastric contents versus peripheral blood.
• The patient had communicated with the visitors via social media, expressing a desire for active euthanasia and to end their life, a plan that went unnoticed.

Implications:

• This case highlights the critical need for increased awareness and monitoring of online information related to euthanasia and its potential misuse.
• Healthcare providers and social networks should be vigilant in recognizing subtle or indirect expressions of suicidal intent, particularly in vulnerable patient populations.
• The findings underscore the challenges in detecting and preventing suicides facilitated by accessible information and methods, necessitating a multi-faceted approach involving medical, social, and technological interventions.
