Ben and Casey Affleck’s mother, Chris Affleck, died at age 83 from cardiopulmonary arrest while visiting her eldest son’s home, her death certificate verifies. She had pancreatic adenocarcinoma for months leading up to her death. Chris had been given six months to live in December after she was diagnosed with the most common kind of pancreatic cancer. The death certificate indicated that she died “visiting son’s residence” at 10:52 a.m. on June 2. “Her greatest wish after her diagnosis, however, was to live to see her grandson graduate high school,” her Boston Globe obituary read.
