From an article:
A bullet was fired into a north Portland home Sunday in a gang shooting.
Police say the bullet went through the outside wall and into ceiling of an upstairs bedroom of the home occupied by five adults and two small children. Investigators believe the family living at the home was not the intended target.
Officers saw three suspects who ran from the scene. Two got away but officers caught and arrested a 15-year-old with a handgun.
The article didn't say how the boy got the gun.
Every gun in the hands of a child must first pass through the hands of an adult.
