According to Variety , Drago died Monday in Los Angeles of complications from a stroke. The actor’s passing was confirmed to EW by his representative.

“Very saddened to hear the news of Billy Drago passing,” Ortiz wrote on Instagram. “He was such an amazing character both on and off the screen. When we were in Morocco filming he’d go off on adventures and no one knew where he was or how to reach him but he’d always show up on time for work with amazing stories of getting lost in the desert and the locals he met and stayed with. Lucky to have worked with you on my first job.”
