77-year-old Chee Tse, who was in the early stages of dementia and reported missing last week after leaving her Larkin Street home, was found dead Sunday night outside Cache Creek Casino on state Highway 16. According to CBS 5, Tse "most likely took a tour bus around 8 a.m. from near Kearny and Clay streets in San Francisco to Cache Creek Casino in Brooks, Thunder Valley Casino in Lincoln or River Rock Casino in Alexander Valley." While there were "no obvious signs of trauma," to her body, her death is currently under investigation.
