A Sacramento teen with terminal cancer who strived to help other sick children achieve their wishes has died. Samantha "Sammie" Dacong died surrounded by family in Sacramento Thursday evening. "Our hearts are heavy today. Our sister, Sammie Dacong, has gone home to God," St. Francis High School, where Sammie was a student, wrote in a message on Facebook. "She embodied what it means to be an SF Troubadour. Her leadership and service shone through even as she bravely battled cancer. As an ambassador for Make-a-Wish, she has made granting the wishes of other sick kids possible."Sammie was only 18 years old, but was battling cancer for the second time. In her final months alive she said, "I found out I have terminal cancer now and my last request is to grant another wish for a child before I pass away." As a child, Sammie beat a rare form of cancer and was a Make-A-Wish kid. She then became an ambassador for the organization, raising money and helping grant other wishes for sick children.Late last year she was diagnosed again with cancer. In May, Make-A-Wish made Sammie an official employee, which was her dream job. She used her last days alive to once again bring attention to the other kids battling cancer."I realize that I'm not the only child dealing with this, I realize there's more people that that need support," Sammie had told KCRA 3. Before her death, she helped raise $128,000 for 13 other children. Her goal was $165,000 in order to become the number one Wish family fundraiser.
