ORLANDO, Fla. (AP) A singer who rose to fame on "The Voice" was shot to death after giving a concert in Orlando on Friday night. Christina Grimmie, 22, died early Saturday.
Orlando Police Chief John Mina says that the suspect who shot and killed Grimmie apparently traveled from another city in Florida to Orlando to confront her.
Mina says the suspect didn't appear to know Grimmie personally and may have been a deranged fan, although the motive was still unknown.
Mina says the suspect had on him two handguns, two loaded magazines and a hunting knife when he confronted the singer.
There were unarmed security guards at The Plaza concert venue and they checked bags and purses for contraband, Mina says.
But Mina says there were no metal detectors or pat-downs of people as they entered The Plaza, a converted Space Age movie house.
Mina says the 21-year-old man fatally shot himself after he was tackled by Grimmie's brother.
The 22-year-old singer from New Jersey finished third during season six of NBC's "The Voice" in 2014, competing on the team of Maroon 5 star Adam Levine.
Grimmie's last Facebook post a few hours before she was fatally shot showed a smiling upbeat young woman asking people to attend her concert.
"Hey guys, what's up?" she said into the camera. She was bubbly and urged fans to stop by the show at The Plaza in Orlando. She closed with an excited "byee!"
The video was posted around 7 p.m. and according to authorities, the concert ended around 10 p.m. Grimmie was shot as she signed autographs for fans at a merchandise table.
Grimmie began amassing a following on YouTube as a teenager, gripping online viewers with her powerful renditions of hit songs. Her videos on YouTube have garnered millions of views.
