A 14-year-old boy falls ill, and dies after an apparent seizure. The hospital staff suspects a bacterial meningitis infection. If the hospital is correct, the boy's friends and family could also be at risk. It's up to Dr. G to find out if the hospital is correct, and if not, find the true cause of death. A 47-year-old man goes to sleep the couch after drinking heavily, and never wakes up. The man had recently had part of his leg amputated due to gangrene. Dr. G suspects that arterial narrowing in other parts of the man's body may have played a role in his death, but she will not know for sure until the autopsy is completed.
