CHARLOTTE, N.C. -- Police are investigating after someone fired shots in to a mobile classroom at Briarwood Elementary School over the weekend.
Lorita Massey was eating lunch with her 7-year-old great nephew in the school's cafeteria when she saw something unsettling.
“We knew something had happened because we seen police kept running around," she said.
Detectives say someone hit the classroom six times.
Authorities believe it happened Saturday night because they got several 911 calls in the area about shots being fired.
A teacher discovered the bullet holes when she arrived at school Monday morning.
The Highland Trace neighborhood backs right up to the school, and there’s a short wooded path that leads right up to the mobile classrooms.
It was on that wooded path that NBC Charlotte found two shell casings; we called police and they sent crime scene techs to collect the evidence.
Massey says she is upset that she now has to have a conversation with her great nephew about guns.
"He's 7-years-old; he shouldn’t know nothing about a gun."
Police say they don't believe there is any danger to the students but they are increasing patrols in the area.
