SorrowΒ clouds the Internet as YouTubeΒ star and The Voice 2014 contestant Christina Grimmie was confirmed dead after being shot by a gunman outside her Florida concert venue Friday night, local time.

The 22-year-old talent had performed at The Plaza Live with punk band Before You Exit and was signingΒ autographs to fans before the fatal moment. Orlando police confirmedΒ in a press conference on Saturday (June 11) the shooter, who shot himself afterwards, had travelled from another city specifically for the event and did not know Grimmie personally. He could have been a “deranged fan”.
