This report presents a fatal case of a young female Type I diabetic patient who developed convulsions and loss of consciousness after taking methamphetamine and spending some time in a dance club. During the convulsions, she was given sugar and when no response occurred, her boyfriend who was not experienced in the use of insulin administered a dose of insulin to her. The woman lost consciousness and died despite the efforts of the emergency service. A biochemical analysis revealed a high level of insulin (196.67 mU/L) and low levels of glucose (2.96 mmol/L) and C-peptide (26 pmol/L). Toxicological analysis revealed a methamphetamine concentration of 389 ng/mL and an amphetamine concentration of 19 ng/mL. The forensic perspective of the difficult determination of the contribution of each of the factors to the death, i.e., the pre-existing medical condition (Type I diabetes), the use of methamphetamine, the physical exertion at the dance club, and, finally, the non-indicated administration of insulin, is discussed. The ruling of the court is also reported.
