Aoki was already sick when he checked himself out of the hospital to take care of his mom who had had a heart attack. And even though his own health wasn't good, he organized a funeral service for his mom and spoke at it upon her death. Just about a month after his mom's service, he passed.
Aoki remained politically active despite his ailments in recent years, including supporting Lt. Ehren Watada, who refused to deploy to Iraq, and attending rallies with friends like activist Yuri Kochiyama. He also supported political prisoners. He made sure to attend Black Panther Party reunions and commemorative events, as well as events for the Asian American Political Alliance and other groups he had been involved in over the years.
He would speak with revolutionary fervor at some of these events. In the last several years, these speeches would wipe him out for several days afterwards but publicly, he never showed that his body was wearing down, according to friends.
His friends have put together a blog where people can share photos and memories. I was particularly struck by this entry by Kei Fischer. Here, she talks about how when Richard was in the hospital two weeks ago, he was worried about getting a letter of recommendation that he had written for her, even though he was so sick. "That small act alone truly characterized the giving, nurturing and self-less human being Richard was," she writes.
