One of Canada's most famous wrestlers has apparently met with a tragic end that also claimed his wife and son.

WWE superstar Chris Benoit, his wife Nancy and son Daniel were reportedly found dead Monday in their Atlanta home after the 40-year-old grappler missed a house show Saturday night and a Sunday night pay-per-view event. He had travelled home to Georgia for family reasons, but didn't elaborate on what they may have been. Benoit, born in Montreal, was also known as "Pegasus Kid" and was widely considered to be one of the stronger technical wrestlers of all time.

The WWE immediately announced plans to scrap Monday's scheduled "Raw" event and will address the tragedy on air.

"There are no further details at this time, other than the Benoit family residence is currently being investigated by local authorities," the WWE statement said on its website.

Renowned pro wrestler Chris Benoit, his wife and their 7-year-old-son, were found dead Monday afternoon in their Fayetville, Ga. home, Atlanta police said.

Police would not give any details on how Benoit, 40, his wife Nancy, and son Daniel died, other than to say they were not shot to death, the Atlanta-Journal Constitution reported Monday. Authorities are investigating the deaths and are considering the possibility of a murder-suicide, where Benoit killed his family over the weekend and himself on Monday. The three bodies were found in different rooms of the home, according to reports.

The news came just a day after Benoit mysteriously pulled out of a World Wrestling Entertainment pay per view event, during which he was expected to be crowned Extreme Championship Wrestling world champion. Various pro wrestling news sources reported that Benoit was unable to appear at the event due to a family emergency.

"There are no further details at this time, other than the Benoit family residence is currently being investigated by local authorities," the WWE said in a statement on its Web site.

Benoit was a 22-year ring veteran and perennial favorite of wrestling purists, who praised his high-intensity style and technical acumen. His aggressive wrestling technique earned him the nicknames "The Crippler" and "The Rabid Wolverine." In 2000 and 2004, he was named Oustanding Wrestler of the Year by the Wrestling Observer newsletter and in 2004 he was named Wrestler of the Year by Pro Wrestling Illustrated magazine.

The Edmonton, Canada native trained to become a wrestler in Calgary, and honed his skills in Japan before becoming a regular on U.S. national promotions in the mid-1990s. Benoit's career highlight took place in New York, when he won his first World Wrestling Entertainment world heavyweight championship in Madison Square Garden in the main event of WrestleMania XX.

Benoit cried as he celebrated in the ring with his wife and son, as well as best friend, wrestler Eddie Guerrero, who died in 2005.

"Wrestling has consumed my life," Benoit said in a 2004 WWE career retrospective video. "Wrestling is my mistress. It's my passion. It defines who I am as a person."

WWE Monday night canceled its scheduled live 3-hour "Monday Night RAW" program, which coincidentally was originally billed as a "memorial service" for WWE chairman Vince McMahon, whose character was recently killed off in a controversial scripted storyline.

McMahon opened the show from center ring in an empty arena and clarified that Benoit and his family had died "in reality." McMahon called Benoit "one of the greatest WWE superstars of all-time."
