An argument over getting out of bed for school Tuesday morning led a teenage boy to open fire on four family members, including his grandmother and two young children, in an East Nashville home, Metro police said.

Nashville police spokeswoman Kris Mumford said that shortly before 7:17 a.m. a relative was attempting to wake up the 16-year-old boy inside his home at Berkshire Place Apartments on Porter Road when an argument broke out.

“There was a quarrel about getting up and getting ready for the day when (at some point) the 16-year-old ran to a closet, got a 9 mm handgun and started firing,” Mumford said.
