Kristina Joanne Ward was 20 and living with her parents in Abbotsford, British Columbia, when she left home on September 25, 2017. She lived with schizophrenia and a developmental disability with an estimated mental age of 12 to 16, and relied on medication to prevent seizures; her family says she took only one dose with her when she left.

On September 27 an RCMP officer briefly encountered Kristina and she told the officer she was alright; as a legal adult the officer respected her privacy. That same evening, between 7:50 and 8:45 p.m., surveillance footage captured her walking at 104th Avenue and 144th Street in Surrey with an unidentified man pushing a bicycle. After that point her cellphone and bank accounts went silent, and the man in the video has not been identified.

Her parents, Art and LeeAnne Ward, have organized annual walks following the route she was last seen to keep attention on the case. The investigation remains open; tips have been received but investigators say none have produced definitive answers. If anyone remembers seeing Kristina that night or recognizes the man in the footage, please come forward with information.
