NASHVILLE, Tenn. — Nashville authorities have released dozens of 911 calls and recordings of emergency dispatches that paint a picture of the chaos, confusion, and fear inside a shooting at The Covenant School on Monday that left three children and three staff members dead.

“I’m hearing rapid fire,” one man, who identified himself as a pastor, said. “Oh Lord Jesus, help us. Protect us, Lord.”

“We need somebody fast,” another caller, who was standing outside, said. “There’s people stuck inside.”

At 10:16 a.m., a caller spoke in a whisper. “Is help coming? Please tell me,” she said. “I’m pregnant. I’m 21 weeks pregnant.”

Others made similar pleas to dispatchers to hurry as they reported dozens of shots ringing out while students and teachers sheltered in their classrooms.

“We are sending the cavalry, trust me, we understand the situation,” a dispatcher reassured one caller.
