Why do you say his death was mysterious? He was a 79 year old diabetic with high blood pressure and a smoker with many health problems which local authorities confirmed with the Supreme Court doctor right after his death. Sleep Apnea being one of those issue. He had a shoulder issue that required surgery, but they did not do the surgery because they felt he might not survive the surgery.

Antonin Scalia suffered from coronary artery disease, obesity and diabetes, among other ailments that probably contributed to the justice's sudden death, according to a letter from the Supreme Court's doctor.

Presidio County District Attorney Rod Ponton cited the letter Tuesday when he told The Associated Press there was nothing suspicious about the Feb. 13 death of the 79-year-old jurist. He said the long list of health problems made an autopsy unnecessary.

The letter dated Feb. 16 said Scalia's many "significant medical conditions led to his death," Ponton said.

In the letter, Monahan listed more than a half-dozen ailments, including sleep apnea, degenerative joint disease, chronic obstructive pulmonary disease and high blood pressure. Scalia also was a smoker, the letter said.

Dr. Mark Hlatky, professor of cardiovascular medicine at Stanford University, said a 79-year-old man with those conditions, especially coronary artery disease and sleep apnea, would be at risk for a potentially fatal heart arrhythmia.

"A lot of people do die in their sleep, and they're found the next day."

The conditions are also associated with pulmonary embolism and stroke, which could also "kill somebody very suddenly."
