Lt. Tommy Pope of the Fayette County Sheriff's Department said the three were found at their home about 2:30 p.m., but refused to release details.

Pope said results of autopsies on Benoit, his wife Nancy, and 7-year-old son Daniel were expected Tuesday.

Benoit, 40, was a former world heavyweight champion, Intercontinental champion and held several tag-team titles over his career.

"WWE extends its sincerest thoughts and prayers to the Benoit family's relatives and loved ones in this time of tragedy," the federation said in a statement on its Web site.

Benoit was scheduled to perform at the "Vengeance" pay-per-view event Sunday night in Houston, but was replaced at the last minute because of what announcer Jim Ross called "personal reasons."

Benoit, a Canadian native, maintained a home in metro Atlanta from the time he wrestled for the defunct World Championship Wrestling.

The WWE cancelled its live "Monday Night RAW" card in Corpus Christi, Texas.
