Autopsy shows Collier had enlarged heart
DECATUR, Ga. -- Atlanta Hawks center Jason Collier died from a sudden heart rhythm disturbance caused by an abnormally enlarged heart, an autopsy showed. The state's chief medical examiner, Dr. Kris Sperry, said Tuesday his testing showed that electrocardiograms administered to Collier, who died Oct. 15 after having breathing troubles at his Georgia home, in 2003 and this year showed "some indication of electrical abnormalities."
