Still No Sign Of Woman Who Went Missing At Rainbow Falls Provincial Park http://www.citynews.ca/news/news_13994.aspx Wednesday August 22, 2007 CityNews.ca Staff After two-and-a-half weeks of intense searching through heavy brush, there's still no sign of 20-year-old Christina Calayca, who vanished while camping with three others at Rainbow Falls Provincial Park near Thunder Bay. The lack of progress has weighed heavily on her family. "They've used K-9 units. They've used planes. They've used submarines. They've used all sorts of different ways in order to find Christina. And nothing, absolutely nothing works. There's no clue at all," said her distraught uncle Ken West. "I won't live without finding my daughter," she said. "I want to see her...I know from the bottom of my heart as a mother, she is alive. She is just kept by somebody. I want to find out who," she adds, referring to a possible kidnapper.
