A woman who survived Sunday's mass shooting at the First Baptist Church where 26 people lost their lives said that her and another survivor "know" that shots were raining down into the room from above and that the shooter was "on the roof."

"I didn't just hear them, I saw them, and then people went down." the woman said in a brief interview with ABC News from the hospital.

According to the witness, the shooter "reloaded" his "shotgun" twice "on top of the roof at the church" before a third volley was fired at churchgoers from inside the room.
