Suspected suicide and suicide attempt with mysterious concomitant circumstances

Two cases of suicide and attempted suicide, respectively, are presented. A 15-year old boy suffering from diabetes died of hyperglycemia after continuous drinking of large amounts of sugared tea. He concealed his disease from the teachers as well as from the doctor. A 52-year old woman was found with multiple blunt force injuries and stab wounds. The suspicion of homicide attempt could be clarified, as all of the injuries were self-inflicted.
