- Medical Conditions Bosworth was diagnosed with non-Hodgkins lymphoma, a cancer of the blood, in 2007. He underwent chemotherapy and went into remission, but the cancer returned in his eye in 2009, and he had more chemotherapy treatments as well as radiation. Bosworth had a bone marrow transplant in April 2010 and went into remission afterwards. By the time of his disappearance, he had been complaining of severe headaches and had been confused and disoriented; his oncologist believes the lymphoma had possibly metastasized in the frontal lobe of his brain. If this scenario did in fact occur and the cancer was left untreated, Bosworth would have become increasingly confused and then die in a matter of weeks or months.
- Distinguishing Characteristics Caucasian male. Gray hair, blue eyes. Bosworth may wear prescription Converse eyeglasses with black rims for reading. He is balding and may have a short gray beard. He has two small scars on the back of his head.
