Former "The Voice" contestant Christina Grimmie has died after being shot following a concert in Orlando, Florida, the singer's representative confirmed Saturday morning. Grimmie, 22, was transported to the hospital after the shooting where she succumbed to her injuries.

Grimmie and the band "Before You Exit" were signing autographs after their show at the Plaza Live Theater when a man walked up to her and opened fire, Orlando police reportedly said. Grimmie’s brother reportedly tackled the shooter before the man turned the gun on himself. Local reports said, citing police, that the suspect, who died after the shooting, was carrying two guns.

"It is with a heavy heart that we can confirm that Christina has passed and went home to be with the Lord," her publicist told E! News. "She was shot at her show in Orlando and, unfortunately, didn't survive the gunshot wounds. We ask at this time that you respect the privacy of her family and friends in their time of mourning. If you'd like to give back to Christina's family in her memory, please consider donating to the families GoFundMe page in their time of need."

Local network WFTV9 reported that witnesses heard at least six shots inside the venue.

"The show ended at approximately 10 o'clock," Orlando Sgt. Wanda Miglio said in a news conference. "After that they were selling merchandise and signing autographs. We know that the suspect walked up and shot Christina at that point. We know that her brother tackled the suspect and that's when the suspect shot himself."

"Her brother is a hero for saving and stopping him from not hurting anyone else," she reportedly added.

Miglio reportedly said that it was unknown if Grimmie, who  finished third on season 6 of the NBC singing competition in 2014, knew the suspect, and that authorities are working to determine the motive behind the shooting.

"We don't know if they were friends, we don't know if he was just a crazy fan that followed her on Twitter, on social media, we really don't know," Miglio said. "We don't know what the motive is right now... This is a very tragic event. This should have been something that was very fun and exciting, and for something like this to happen is just a tragedy."

Several photos from the shooting site were shared on social media, while fans and several celebrities expressed their shock at the incident.

"The Voice" judge Blake Shelton took to Twitter to react to Grimmie's shooting.
