“It is with a shattered heart that I share that the brilliant Josh Grisetti took his own life on Friday,” McClure wrote on social media. “I’m not ready to even attempt to understand. My heart is with his wife and family as they try to deal with the reality of this. Some of my all-time favorite memories were by this man’s side, playing his brother onstage for years, watching him inspire students while transforming the Musical Theatre program at Cal State Fullerton …and having the honor of being the Best Man at his wedding. Maggie and I are beyond heartbroken. Communities around the world will never be the same without him. We love you Josh. Just a cataclysmic loss. Memorial info to come in time.”
