A US singer has been shot and killed while signing autographs following her concert in Orlando.
A popular contestant on singing show The Voice, Christiana Grimmie was killed when a man walked up to her and shot her, before being tackled to the ground by the pop star's brother. The gunman then turned the firearm on himself.
Grimmie received immediate medical treatment and was rushed to Orlando Regional Medical Center, but has since died.
Sergeant Wanda Miglio says Grimmie's brother acted heroically and prevented others at the scene from injury, but says information is scarce thus far.
"This should have been something that was fun and exciting, and for something like this to happen is just a tragedy," she says.
Sgt Miglo says the gunman has not yet been identified, and so it is too early to say what his motive was or whether he knew the singer.
