The man who shot Christina Grimmie dead following her concert performance in Orlando on Friday has been named Kevin James Loibl, 27, from St Petersburg, Florida.
The police believe he travelled to the gig with the intention of killing Christina.
The singer opened for the band Before You Exit at The Plaza Live in Orlando and stayed on afterwards to sign autographs for fans when the attacker — who was carrying two handguns, two loaded magazines and a hunting knife — approached her and opened fire.
During a press conference Orlando Police Chief, John Mina, said it was likely that the man was a deranged fan and that Christina did not know him.
He said: "That would be speculation, but that's what it's looking like. There's no indication that he knew her."
He added that police were currently searching through the Loibl's phone and computer to find a possible motive for the murder.
The police chief further said: "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 turned the gun on himself.
