Muhammad Ali, the former world heavyweight boxing champion, died at age 74 of septic shock due to unspecified natural causes, a family spokesman said on Saturday (June 4).

“Shortly after I arrived it became clear in discussions with Lonnie Ali and with his doctors that his condition wasn’t going to improve and they were able to bring all family members in the last 24 hours when we knew things weren’t going to improve they were given time to say goodbye,” family spokesman Bob Gunnell said at a press conference in Scottsdale, Arizona. “His official cause of death was septic shock due to unspecified natural causes.”

Ali, who had long suffered from Parkinson’s syndrome, died at 9:10 p.m. MST on Friday, June 4 Gunnell said of the boxing legend, who had recently been hospitalized at the Scottsdale Healthcare Hospital for a respiratory issue.
