William Ritchie, former head of criminal investigations for the Washington, D.C., police force, wrote on Facebook: “As a former homicide commander, I am stunned that no autopsy was ordered for Justice Scalia… My gut tells me there is something fishy going on in Texas.”

"I was stunned that at this day and time with someone as important as a justice sitting on the Supreme Court, you would have a haphazard investigation," Richie told INSIDE EDITION.

Justice Scalia was found dead in his bed in a hotel suite at the 30,000 acre Cibolo Creek Ranch in west Texas on Saturday.

The ranch owner says he discovered Scalia with "a pillow over his head" but a local judge pronounced him dead of natural causes without seeing the body or performing an autopsy, which is permissible under Texas law.

Ritchie said: "I am not suggesting foul play, I am saying do a thorough investigation."

Meanwhile, we're learning new details about the 79-year-old Scalia’s health problems.

He had a history of heart trouble and high blood pressure, and was considered too weak to undergo surgery after injuring his right shoulder, a friend said.

Bryan Garner, a close friend of Scalia’s, told CNN that Scalia called him last Wednesday, after a doctor's visit.

Scalia said, "Bryan, I will have to live without playing tennis for the rest of my life," Garner recalled.

"Little did I know that the rest of his life would be 36 hours.”
