ORLANDO, FL - Singer Christina Grimmie, who starred in NBC's "The Voice," died early Saturday after a gunman shot her following a performance in Florida, authorities said.
A man armed with two guns walked up to the 22-year-old singer as she was signing autographs late Friday night and opened fire, Orlando Police spokeswoman Wanda Ford said.
The gunman fatally shot himself after Grimmie's brother tackled him, according to authorities.
Orlando Police Chief John Mina says that the suspect who shot and killed a singer who rose to fame on "The Voice" apparently traveled from another city in Florida to Orlando to confront her.
Mina says the suspect didn't appear to know Christina Grimmie personally and may have been a deranged fan, although the motive was still unknown.
"Her brother is a hero for saving and stopping him from not hurting anyone else," Ford said.
The singer had performed at The Plaza Live theater Friday night, along with the band Before You Exit, when the shooting broke out. She was rushed to a hospital in critical condition and died a few hours later.
"It is with a heavy heart that we can confirm that Christina has passed and went home to be with the Lord," her publicist Heather Weiss said in a statement.
"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."
Grimmie finished third on Season 6 of "The Voice." She was discovered on YouTube, where she has a massive following.
Before the shooting, the singer posted video on social media encouraging fans to come out to the theater.
It's unclear how the gunman got a gun into the venue or whether attendees were checked for weapons.
Police have not named the suspect or given a motive for the shooting.
