The teen was arrested on murder and other charges.
Police say each victim was shot more than once.
They believe the boy is related to the victims and say he lives in the home where the shootings took place.
Several firearms were found in the home, including a semi automatic rifle.

Neighbors say the victims are members of the Griego family.
