WFAA TV in Dallas reports that Justice Antonin Scalia’s death was due to a heart attack; there are still conflicting reports about whether an autopsy will be performed, but the Washington Post says Scalia’s family declined an autopsy.

Guevara said she asked the Marshals if there were “’any signs of foul play.’ And they said, ‘Absolutely not,’’’ she told the station. After talking with Scalia’s personal physician, she said, she pronounced him dead and declined to order an inquest.

Scalia’s body was taken to Sunset Funeral Home in El Paso, Texas, by a procession of about 20 law enforcement officers. It arrived there at about 2:30 a.m. Sunday, according to Chris Lujan, a manager for the funeral home. The funeral home is about three and a half hours from the ranch where Scalia died.

Lujan said that Scalia’s family did not request an autopsy and that the body is being prepared for the funeral and will be transported back to Washington on Monday. It is under guard by six law enforcement officials, including U.S. Marshals and Texas state troopers, Lujan said.

“An autopsy was declined at about 3:30 a.m.,” Lujan said. “The Justice of the Peace said there was no indication of foul play and that he died in his sleep from natural causes.”
