Christina was gunned down while signing autographs following her performance with Before You Exit at The Plaza Live in Orlando on June 10, 2016. The shooter was 27-year-old Kevin James Loibl, an obsessed fan who was tackled by her brother and eventually took his own life.

Back in 2014, Christina, who was known as a YouTube star and a former "The Voice" contestant, revealed that her mother had survived breast cancer four times. "My mom has had breast cancer four times, now. And she just got put back on chemo again," she said in an interview with AXS at the time.
