Alleged shooter Trystan Andrew Terrell, 22, shot six students. Two of those students died: Riley Howell, 21, and Reed Parlier, 19.
Listen to the 911 calls below:
Students called from the Kennedy and Macy buildings, saying they could hear the gunman nearby.
"There is someone shooting," one caller said. "Last time I saw them they were in Kennedy Hall, I believe they moved to the library."
Listen to the 911 calls. Warning some files may be distubring to some.
"We heard five shots," another caller said in a panic. "We don't know how many shooters."
"It seems like he was shooting at one person," someone said while trying to help piece together the events. "He fired a lot of shots."
At least one of those shots hit Riley Howell.
After realizing he had no place to run or hide in his classroom, Howell took matters into his own hands by taking "the fight to the assailant."
Howell died during his selfless act. In fact, Charlotte-Mecklenburg Police Chief Kerr Putney said Howell's actions helped capture Terrell.
After the gunfire stopped and the scene was clear, Terrell was placed under arrest.
Howell and Parlier were dead. Drew Pescaro, 19, Sean Dehart, 20, Emily Houpt, 23, and Rami Alramadhan, 20, were on their way to the hospital.
Pescaro and Dehart both attended high school in Apex. They, along with Houpt and Alramadhan, are expected to recover.
Terrell is facing two counts of first-degree murder, four counts of attempted first-degree murder, four counts of assault with a deadly weapon with intent to kill, possession of a firearm on educational property and discharging a firearm on educational property.
His first court appearance was scheduled for Thursday; however, he waived his right to be present.
Terrell enrolled at UNC Charlotte in the fall of 2018. He was studying history but dropped out last semester.
