An autopsy has been conducted on the remains of Ryan Knight, but the cause of his death has not yet been determined. The 29-year-old "The Real World: New Orleans" veteran was found dead Thursday morning at a friend's house in Wisconsin, reportedly after a night of heavy drinking. The autopsy performed on his body Friday proved inconclusive and the cause of death will be determined after toxicology and other tests are finished, TMZ reported. Police in Kenosha said no drugs were found at the scene. Knight's family told TMZ he had been complaining about stomach problems for the past few days. News of his death arrives shortly after Diem Brown -- another member of "The Real World" television franchise -- died of ovarian cancer at the age of 32.
