Christina Grimmie's family filed a lawsuit over her death

The 22-year-old star's family are suing concert promoter AEGLive SE and the Orlando Philharmonic, which owns the Plaza Live Theatre, where Christina was gunned down by a crazed fan in June. According to Billboard, the lawsuit states: "The death of Christina was caused by the negligent and culpable conduct of the defendants who failed to provide adequate security measures to protect Christina at the Plaza Live Theatre on June 10, 2016." The security company, who were working the event, have also been named in the lawsuit, with the plaintiffs arguing that only "superficial bag checks" were carried out on the night Christina died. The gunman Kevin James Loibl entered the venue with two handguns, two full magazines and a large hunting knife before shooting Christina in the head and chest. Christina's brother Marcus tacked Loibl and was praised for preventing further injury or loss of life. Her family are seeking damages for their mental pain and suffering, along with compensation for Marcus' emotional and physical trauma. And Marcus and his parents Albert and Tina are also asking for compensation for the loss of future earnings from Christina, who "provided financial support to her parents", along with money for medical and funeral expenses. Previously, Christina's family paid tribute to her "joyful heart and beautiful voice." In a joint statement on a GoFundMe page, they said: "The outpouring of love and generosity that has been displayed to our family throughout these last few weeks has far exceeded anything we could have ever imagined. "As we have always known, Christina's life was so very special, not only to us, but to everyone she touched with her joyful heart, beautiful voice and love for life and the Lord. "Words cannot express what the many memorials, donations and tributes shared by Christina's fans and those in the media and entertainment industry mean to us. "She will live on in our hearts forever."
