The cause of Pat Finn's death has been determined more than two weeks after his untimely passing at the age of 60. According to his official death certificate obtained by PEOPLE, the actor's demise was a result of malignant neoplasm of the bladder, more commonly known as bladder cancer. The document further indicates that Finn had been living with the diagnosis for "years" and no autopsy was performed. It also confirms that he died at his home in Los Angeles.
Last month, a representative for the Friends actor shared in a statement to PEOPLE that he passed away on December 22. "Confirming the very sad news that Pat passed away on December 22," the statement read. "He was the kindest, most joyful person in any room and was surrounded by his incredibly close and loving family and friends. We will all miss his big smile and even bigger heart."

His family also shared their own statement, remembering Finn — who is survived by his wife of 35 years, Donna, and their three children, Cassidy, Caitlin, and Ryan — for his laughter and love for his favorite sports team. "After a beautiful life filled with laughter, love, family, and friends, we share the heartbreaking news of the death of Pat Finn," the late actor's family said. "Pat bravely battled cancer over the past few years. We know heaven is going to have quite the party with Pat Finn’s arrival. In Pat’s final days, he often showed the biggest signs when the Bears scored a touchdown. No pressure Bears - just saying - do it for Pat."
The statement concluded, "His life and legacy will be carried on through his beautiful family, including his wife Donna and three children, Cassidy, Caitlin, and Ryan, and the thousands of friends and family that he impacted."
Finn was best known for playing Bill Norwood on the ABC sitcom The Middle from 2011 until its conclusion in 2018. He also appeared in hit '90s sitcoms such as Seinfeld, where he played Joe Mayo, and Friends, portraying Monica (Courteney Cox)'s boyfriend Dr. Roger. Among his many other credits were his main role on The George Wendt Show as Dan Coleman in 1995 and a part in Murphy Brown as Phil Jr. from 1995 to 1997.
Following the news of his death, Finn's daughter, Cassidy, was one of several who paid tribute to her late father. "Dad… you were and are a role model and an inspiration to everyone you met," she wrote in a heartwarming Instagram post on December 24. "I tried to think of a word to describe you, but no word could ever do it justice. You are Pat Finn," she wrote alongside a series of photos from her childhood.
"The least shocking thing was hearing the nurses say they have never seen so many people show up at a hospital for someone. That was my dad," she continued. "My life is forever changed because of him. He taught me to be funny, positive, humble, to listen, to always try my best, to love, and to surround myself with the best people. But most importantly—you taught me kindness."
"I've never met a single person who had a bad thing to say about my dad," Cassidy concluded. "I feel like the luckiest person in the world that I got to call you my dad. Can't wait to drink an Old Style with you again one day. I love you 10, Dad. Ok. :)"
