FORT LAUDERDALE, Fla. -- Two Marjory Stoneman Douglas High School students hid alone in a classroom, petrified as the sound of gunfire overtook the 1200 Building, according to a recording of a 911 call made during the Feb. 14 mass shooting at the Parkland school.
"She's terrified right now," the caller told the dispatcher. "She's afraid to talk, they're hiding right now."
The caller was on the line with a mother who was talking by cellphone to one of her two daughters at the school.
"Be quiet, be quiet, keep the phone line open," the dispatcher warned. "Don't move. Just stay hidden."
This was one of the 81 calls to come into the Broward Sheriff's Office during the shooting from 2:22 p.m. to 3:35 p.m. The agency on Thursday afternoon released recordings of 10 of the calls.
Nikolas Cruz, 19, has admitting to carrying out the shooting that killed 17 students and faculty and wounded 17 others.

A Broward County grand jury on Wednesday indicted Cruz on 17 counts of first-degree murder and 17 counts of attempted first-degree murder. He has an arraignment hearing scheduled for March 14.
Only one of the released calls has been identified as coming from within the building, that of someone whispering someone was shooting in the school.
"Someone's shooting up the school at Stoneman Douglas," the caller whispered.
Heavy breathing and inaudible whispering followed. The dispatcher repeatedly asked the caller to repeat himself.
