(CNN)An American tourist who is legally blind and eventually will totally lose her sight was last seen more than a week ago on a trail near a small village in Peru, her brother said Saturday.
The new witness information puts Carla Valpeoz, a 35-year-old social activist and experienced traveler from Detroit, in Pisac on December 12, Carlos Valpeoz said in an email to CNN.
He wrote that three people — a bus driver, a trail employee and an archeologist — each saw his sister, who has very low vision and uses a cane when she travels. They said she was by herself.
