Friends and family of Yanfei Bao, who was killed in Christchurch in July last year, gathered today to pay tribute to their loved one. Among those who attended today's service was her father, who had travelled from China, and described his heartbreak over his daughter's death. The 44-year-old mother and real estate agent went missing last July, and her body was found a year later in farmland on the outskirts of Christchurch. Chinese national Tingjun Cao is currently on trial in the High Court at Christchurch, accused of her murder. Rachel Graham reports.
