Judge Cinderela Guevara of Presidio County said on Monday that she spoke with Justice Scalia’s doctor on Saturday, shortly after he was found dead in his room at a remote Texas ranch. She said the doctor told her that Justice Scalia, 79, had a history of heart trouble and high blood pressure, and was considered too weak to undergo surgery for a recent shoulder injury.

Unlike presidents, the Supreme Court’s members do not provide regular health disclosures.

Judge Guevara said that she consulted with the physician and local and federal investigators, who said there were no signs of foul play, before concluding that he had died of natural causes. She said she spoke with a “Dr. Monahan” after 8 p.m. on Saturday to discuss Justice Scalia’s health history.
