Christian singer Christina Grimmie was fatally shot without knowing who her attacker was, CNN reports.

The gunman—Kevin James Loibl, 27, of St. Petersburg, Florida—shot Grimmie, 22, who finished third in Season 6 of NBC's "The Voice," on Friday night at the Plaza Live Theater in Orlando, Florida.

After police searched Loibl's computer, phone and other belongings, they could not find any motive for his attack, police sources told CNN.

Orlando Police Chief John Mina suspects Loibl drove to Orlando to shoot the singer "then had plans to travel back to where he came from."

Grimmie was signing autographs for her fans when she was shot, reports say. She had just finished performing as the opening act for the band Before You Exit when Loibl shot her.

Loibl carried two handguns, two additional loaded magazines, and a hunting knife. He was tackled by Grimmie's brother Marcus after the attack. However, before police authorities could determine what his motive was for the attack, Loibl shot and killed himself.

Grimmie was immediately rushed to the hospital where she died from her gunshot wounds on Saturday.

The Grimmie family is grateful for the outpouring of love and support shown to the singer after her passing. "I really don't have much to say about anything and am just blown away with the prayers and support. Christina was more than my sister. She was a partner in life," her brother posted on his Facebook page. " A superstar. A goofball. Introverted. And a friend to everyone. Genuinely. But above all...she was my baby sister."

The Plaza Live also issued a statement extending its condolences to the victims, and decided to suspend upcoming activities and events "until further notice."

"Our thoughts and prayers are with the families of those lost as well as those that witnessed and aided in the recovery after this senseless act," the statement reads.
