A shooting involving US rapper ScHoolboy Q - who performed in New Zealand last weekend - after a concert at the historic Red Rocks amphitheatre west of Denver was probably not random, police say.
"This is not just a coincidence. We think there is probably more to it than that," said Jacki Kelley, a spokeswoman for the Jefferson County Sheriff's Office on Saturday.
"It does seem to be more targeted than random."
The rapper was not hurt in Thursday night's shooting but three other people in the vehicle he was in sustained injuries. One was released from the hospital Friday morning.
No arrests have been made but Kelley said investigators had received numerous tips and were trying to determine a motive for the attack in a parking lot at the outdoor venue, where the Beatles and Grateful Dead have performed and U2 filmed Under a Blood Red Sky.
