A 21-year-old man wielding two handguns shot former "The Voice" contestant Christina Grimmie after a Friday night concert in Florida, and then fatally shot himself, police said Saturday.

Grimmie, 22, died from her injuries from the shooting, which happened around 10:30 p.m. ET at The Plaza Live in Orlando. The singer had opened for the band Before You Exit and was meeting fans and signing autographs a half hour after the concert ended when she was shot.

Police hailed Grimmie's brother as a hero, and said he tackled the suspect, whom they described as a white male with two loaded magazines and a large hunting knife in addition to the two handguns he was carrying.

"Almost immediately, her brother Marcus Grimmie tackled the suspect," Orlando Police Chief John Mina told reporters Saturday. "Shortly after that, the suspect killed himself."

Police did not release the attacker's identity, but said he had traveled to Orlando from his home somewhere else in Florida.

"The suspect traveled to Orlando apparently to commit this crime and then had plans to travel back to where he came from," Mina said.

Detectives were scouring his cellphone and computer to find a motive for the killing. Mina said there was "no indication" so far that he knew Grimmie.

The shooting happened inside the venue as about 120 concertgoers crowded around Grimmie for a chance to meet her and buy merchandise. Fans' purses and backpacks are typically checked when they enter The Plaza Live, but there are no metal detectors there, Mina said.

"This isn't a crowd that you would suspect would be carrying guns into a venue like this," he said of fans of Before You Exit, an Orlando pop/rock band.

The Plaza Live said in a statement that it was "deeply saddened by the tragic events," and would be suspending all events there until further notice, including a Kidz Bop concert that was scheduled for Saturday night.

Detectives planned to meet with Grimmie's family later Saturday.

The name of her killer could be released as early as Saturday afternoon, Mina said. It wasn't clear whether the man had a prior criminal record.

It's "unknown what his plans were for after killing Christina, but very heroic actions by Marcus Grimmie to jump in definitely could have prevented future loss of life there," Mina said.

A witness said multiple shots were fired.

Josh Call, who was working at a vegan hot dog stand outside the venue, told the Orlando Sentinel he heard four or five shots.

"It was quick like pow, pow, pow," he told the paper. After a few minutes, he said he went inside and saw a man and a woman on the floor bleeding heavily.

"It was horrifying," he told the Sentinel.

Grimmie, a native of Marlton, New Jersey, came in third place on Season 6 of "The Voice," NBC's singing competition, which aired in 2014. She was just 19 when she auditioned with Miley Cyrus' "Wrecking Ball" and chose Maroon 5 lead singer Adam Levine as her coach.

Levine posted a photo of himself with Grimmie on Instagram, commenting before her death was confirmed: "I'm sad, shocked and confused. We love you so much Grimmie. We are all praying hard that you can pull through this ... this just isn't fair."


Before You Exit called the singer "such a loving, caring, beautiful person with the biggest heart" in a statement posted to Twitter hours after her death was announced.

"She was an absolutely incredible musician and an even better friend," it added. "We are so so saddened by her passing and are completely heartbroken."

Tonight we lost a singer, friend, daughter, sister, etc in the beautiful Christina Grimmie. Praying for all those who are hurting tonight

Mark Grimmie told The Philadelphia Inquirer in 2014 that he was in awe of his sister's talent.

"I'm done being surprised by cool things she does. She's very talented and she's worked incredibly hard — it's a dangerous combination," he said.

She's pretty low on the celebrity scale. Given that her brother tackled the gun man security could well have been non-existant. Which could explain why she was shot.
Famous enough for people to vaguely pay attention, unknown enough to be easy to get to.

Horrible. No closure for anyone here. I can't imagine being her brother right now.

Tragic news. Have to ask, a bit confused on the details. The brother tackled gunman, who fatally shot himself? During the struggle or did he tackle the gunman after he shot himself?

While I do not know the full details, I assume during the struggle the gunman shot himself in an attempt to not be taken in.
