“Our beloved client Jeff Conaway passed away at 10:30AM,” tweeted Phil Brock, Conaway’s manager earlier today. “We loved him as a person, respected him as an artist and he will be always remembered.”

The actor had been hospitalized in a medically induced coma since May 11, when he was found unconscious. Conaway was battling pneumonia and sepsis. “Jeff was taken off life-support [Thursday] afternoon,” Brock told People. “His family chose to take him off of life-support based on advice from physicians. They thought for several days that the situation was hopeless.”

The 60-year-old struggled with drug and alcohol addiction, appearing on 2008’s “Celebrity Rehab with Dr. Drew.” Brock said the combination of pain killers Conaway was taking for a back injury made it difficult for the actor to realize the extent of his illness.

“Jeff Conaway was a wonderful and decent man, and we will miss him,” John Travolta, who starred with Conaway in “Grease,” said to E! News. “My heartfelt thoughts are with his family and loved ones at this very difficult time.”
