Bob Saget, an actor and comedian, best known for portraying the cheery father on the television comedy "Full House," was discovered dead in a hotel room in Orlando, Florida, on Sunday, authorities and his family said.

Saget's cause of death was unknown. On Sunday afternoon, emergency responders discovered the actor unresponsive in a room at the Ritz-Carlton in Orlando. According to the Orange County Sheriff's Office, they pronounced him dead at the spot.

Detectives discovered no evidence of foul play or drug use, according to the department. Saget had recently begun a comedy tour and performed Saturday night near Jacksonville, Florida. He reminisced on the "really nice audience" and "lots of positivity" in his most recent Instagram post.

"I had no idea I had just completed a two-hour set," he wrote. "I'm back in comedy, just as I was at the age of 26. I suppose I'm discovering my new voice and relishing every minute of it."

Saget portrayed widower father Danny Tanner on "Full House" from 1987 to 1995 and in its 2016-2020 sequel, "Fuller House." Tanner shared his house with his three children, brother-in-law, and best buddy on the show.

From 1989 to 1997, he also presented "America's Funniest Home Videos."

Saget's stand-up show featured raunchier adult-oriented comedy, unlike his innocent television persona. He also appeared in a recurring role as a caricature of himself on the HBO series "Entourage."

"We are heartbroken to confirm Bob's death today," the Saget family said in a statement.

"He was everything to us, and we want you to understand how much he loved performing live and bringing people from all walks of life together through laughter," the family stated.

Saget's co-star on "Full House," John Stamos, described himself as "broken" and "gutted" by Saget's death.

"I am absolutely stunned," Stamos commented on Twitter. "I will never have another friend like him in my entire life. I adore you, Bobby."

In a Sunday tweet, comedian Jon Stewart described Saget as "just the funniest and nicest." Jason Alexander, star of "Seinfeld," said Saget "was kind and dear and genuinely cared about people." He embodied the phrase 'a nice egg.'"

The sheriff's department stated that the local medical examiner's office would determine Saget's death.
