ORLANDO - Florida authorities say "The Voice" star Christina Grimmie died after being shot at a concert venue in Orlando by a suspect who fatally shot himself after being tackled by the singer-songwriter's brother.

Orlando Police Department officials said during a news conference that Grimmie was shot about 10:45 p.m. Friday at The Plaza Live, where she had performed earlier. They say the suspect 27-year-old Kevin James Loibl "walked up and shot" Grimmie after the performance, while merchandise was being sold and autographs were being given. Grimmie's brother tackled the shooter, who shot himself.

Orlando Police Chief John Mina says Loibl apparently traveled from another city in Florida to Orlando to confront her.

Mina says Loibl didn't appear to know Christina Grimmie personally and may have been a deranged fan, although the motive was still unknown.

Grimmie, a 22-year-old New Jersey native, finished third during season six of NBC's "The Voice."

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. The 22-year-old 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.
