A founding member of the band Chicago has died at age 81 following a prolonged health battle, according to reports from Daily Mail and Mail Online. The musician died shortly after 2 a.m. on Wednesday morning while in hospice care. The outlets say the death comes after roughly six years of illness, during which she battled Alzheimer’s disease. Both accounts attribute the information to a statement she previously shared, describing her time in hospice and the duration of her condition. The reports provide the same timing and broad medical history, including Alzheimer’s and the length of the health struggle, but they do not include further details about funeral arrangements, survivors, or confirmation from the band or medical officials. The stories therefore focus on the circumstances of death—time of death, hospice care, and the illness history—and do not add additional verified context beyond that shared information.
