It's because people who knew him and were close to him didn't reveal much about the date of death, the exact cause or other details. Wikipedia [1] just states this: > Ritchie was found dead on October 12, 2011, at the age of 70 at his home in Berkeley Heights, New Jersey, where he lived alone. First news of his death came from his former colleague, Rob Pike. The cause and exact time of death have not been disclosed. He had been in frail health for several years following treatment for prostate cancer and heart disease. Even Rob Pike heard of this news and didn't have more information.
