After a personal three-year struggle with ALS, Sandra Bullock’s longtime partner Bryan Randall passed away at the age of 57.

Bryan Randall’s family told PEOPLE, “It is with great sadness that we share that on August 5, Bryan Randall passed away peacefully after a three-year battle with ALS.”

Bryan made the decision early on to keep his ALS diagnosis a secret, and those of us who cared for him tried our best to comply.

The family statement continued, “We are incredibly grateful to the tireless doctors who navigated the terrain of this illness with us and to the amazing nurses who became our roommates, frequently sacrificing their own families to be with ours.”
