A teenage boy fatally shot two adults and three children inside an Albuquerque home, authorities said Sunday.

The boy was arrested and booked on murder and other charges in connection with the shootings Saturday night, Bernalillo County sheriff's spokesman Aaron Williamson said.

The victims' identities haven't been released, and the boy's motive and connection to the five victims weren't immediately unknown. Williamson said investigators were trying to determine if the victims were related.
