There are still many unanswered questions into the shooting death of former "Voice" star Christina Grimmie in Orlando.
Grimmie, a New Jersey native, placed third on season six of NBC's "The Voice." She is also a YouTube sensation.
Police say 27-year-old Kevin James Loible traveled from St. Petersburg Friday night to attack the pop star following a concert Grimmie was performing at.
A memorial continues to grow outside The Plaza, as many mourn the loss of the talented star.
"It was just a senseless death. It didn't need to happen," says one fan.
Officers say Grimmie was signing autographs after the concert when Loible approached her with two hand-guns and a hunting knife.
Loanmi Fortun of Kissimmee heard everything.
"I think three popping sounds," says Fortun.
Police say Grimmie's brother tackled Loibl. That's when the suspect turned the gun on himself.
Detectives say it appears Loibl did not know the pop star.
"Now they are going through the suspects cellphone and computer to see if they can find a motive," says Orlando Police Chief John Mina.
Some guests at the concert questioned security.
"If I were the owner of this establishment I would not open until measures were taken," says Fortun.
Purses and backpacks are checked when guests come in.
"Young kids. This isn't a crowd that you would suspect would be carrying guns into a venue like this," says Mina.
Staff at The Plaza Live released a statement saying they are suspending activities and events at the venue for the time being.
