Pat McGuckin barely recognized her 39-year-old son. Once a personal trainer and bodybuilder, Michael now was exhausted, his limbs bloated, his mood so volatile that he ripped the phone off her wall.
He told his worried mother that he was in pain from a car accident but that a doctor was helping him.
On Oct. 21, 2007, his younger brother found Michael in bed, his body cold. A few days later, their mother stared at the words on the death certificate, struggling to understand what had killed her son.
