Cruz shared the devastating news in a Facebook post. The actor included a picture of himself with McCool (above), who was his mother's stepsister, according toET. He wrote,
"This was the last time I saw Brenda McCool. She was with us when our grandfather passed this passed fall. She was a fighter. A cancer survivor. A stellar mother. A proud and fierce advocate for her LGBT family. She spoke passionately about how much she loved her children. She was hilarious and loving and tore up the dance floor when salsa or anything was playing. I can't believe she's gone. I mourn with her kids and my entire family. The violence and hate has to end. The guns have to fucking GO! Our hearts are BROKEN! #Pulse #orlando"
Cruz also gave an emotional speech remembering McCool during the Logo Trailblazer Honors. Dressed in a gray John Varvatos suit, the actor spoke highly of the woman he grew to love and respect. Watch his speech here:
