Frasier Star John Mahoney's Cause Of Death Revealed

The beloved actor's official cause of death has been revealed.

On Wednesday, Feb. 7, 2018, TMZ reported that Frasier star John Mahoney passed away from multiple health complications, including lung cancer, brain disease, and seizures. According to the gossip rag's sources, the actor, who also reportedly suffered from kidney disease and diabetes, has since been cremated.

As Nicki Swift previously reported, Mahoney's publicist confirmed that the actor died at the age of 77 following a short illness on Sunday, Feb. 4, 2018, while in hospice care in Chicago, Ill. He was best known for playing Frasier and Niles' ex-detective dad Martin Crane for 11 seasons on the hit '90s sitcom Frasier.

Since then, Mahoney's former Frasier co-stars have reacted to the sad news. "He was my father," Kelsey Grammer, who famously played the titular role, tweeted, captioning a sweet snapshot of the two embracing. "I loved him."

Peri Gilpin, who portrayed Roz Doyle on the NBC series, also took to Twitter. Sharing a photo of Mahoney singing at her wedding, she wrote, "Watch Moonstruck, Say Anything and/or Frasier or anything you can with him in it and raise a glass to John. Remember him well."

Meanwhile, Jane Leeves, who played Daphne Moon on the show, honored Mahoney in a statement to TheWrap. "John was the dearest sweetest man I have ever known," she said. "His wicked sense of humor, usually whispered in your ear or spoken just loud enough that only you could hear could bring you to tears. And his smile. Oh my god. He was lit from within. How lucky I am to have had him in my life. I loved him so much and will miss him so terribly."

At the time of this writing, David Hyde Pierce, who played Niles, has yet to publicly comment on Mahoney's passing.

With a career spanning over 30 years, Mahoney starred in a number of films, including Moonstruck and Say Anything. The British-born actor most recently had a recurring role as Betty White's love interest on Hot in Cleveland, on which he reunited with Leeves. After Frasier wrapped in 2004, he pursued a quieter life and returned to the theater, working mainly in Chicago.
