A Spokane couple doing missionary work in Africa died over the weekend in a plane crash in northwest Zambia, leaving behind two young children. Jay and Katrina Erickson, who attended Hillyard Baptist Church, were killed Saturday when the six-seat Cessna aircraft Jay was piloting crashed into the Zambezi River. Their daughters, 2-year-old Marina and 1-year-old Coral, had stayed behind at the Chitokoloki Mission Hospital where the couple worked.
