Ho-Henry's body was found less than a week after the funeral for Hawaii entertainer Don Ho, who died April 14 of heart failure, The Honolulu Advertiser said.
Her brother, Dwight Ho, said Ho-Henry, 51, was pronounced dead Friday morning.
"We're having a hard time," he said. "We're just trying to pull together, get everybody together. We're terribly sad and trying to cope."
Ho-Henry had been staying with a friend on the North Shore, Dwight Ho said.
