Cancer diagnosis

In August 2015, Haggerty received more devastating news: he was diagnosed with spinal cancer following the discovery of a tumor during back surgery.

The news shook him and his loved ones to the core. Despite putting up a brave fight, the cancer ultimately claimed his life on January 15, 2016, in Burbank, California. He continued working right up until his passing; his Internet Movie Database page indicates that he had three films in post-production in 2016.

Haggerty’s passing left a profound void in the hearts of many, as his legacy as Grizzly Adams and his vibrant presence in the entertainment industry will forever be cherished and remembered.

”He wasn’t a choirboy by any stretch of the imagination. He was a pirate! He would light up any room he walked into – he had infectious laughter,” his longtime friend, Terry Bomar, said.
