The former The Voice finalist was killed by 27-year-old Kevin Loibl at a post-concert meet and greet in Orlando, Florida on 11 June (16), when the deranged fan then took his own life.

An autopsy on both bodies was performed in the wake of the tragedy, and now officials at the Orange County Medical Examiner's Office have released their findings, in which they declare Grimmie's death a homicide.

The documents also revealed no drugs were found in the systems of the 22-year-old singer or her killer, who died from a self-inflicted gunshot wound to the head.

Following Christina's death, her coach on The Voice, Maroon 5 frontman Adam Levine, offered to pay for her funeral, while Selena Gomez's stepfather Brian Teefey, who had served as the young star's manager, created a GoFundMe page to raise money to support the family.

Christina's funeral took place on 16 June (16) in New Jersey, and thousands of mourners attended a public memorial the following day, when the family expressed its gratitude for the outpouring of support.

"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," her relatives stated. "She will live on in our hearts forever. We will take our time in determining the best ways to honor Christina moving forward."
