"I did go out recently and sign [autographs] for some fans... and I do feel better about this. I do need to be careful, but I can still do this. I don't have to be afraid of the world. That's my biggest fear on top of that, to be afraid to go outside."
Christina had opened for the band Before You Exit at The Plaza Live in Orlando and stayed on afterwards to sign autographs for fans when Loibl - who was carrying two handguns, two loaded magazines and a hunting knife - approached her and opened fire.
Police believe he came to the gig with the intention of killing Christina.
The police chief added: "He came here to commit this crime and had plans to travel back to where he came from."
However, after Christina's brother tackled Loibl, the murderer killed himself.
