The shooting at UNC Charlotte Tuesday that killed two students and injured four others happened in the classroom of an anthropology class taught by a former Lee County High School graduate, according to several sources.

Adam P. Johnson, an adjunct professor who has been with UNC Charlotte for four years, was leading team presentations his in Anthropology and Philosophy of Science course in the Woodford A. Kennedy Building at 5:40 p.m. Tuesday when 22-year-old Trystan Terrell began shooting a pistol at students.

Terrell was arrested, taken into custody and charged with two counts of murder, four counts of attempted first-degree murder, four counts of assault with a deadly weapon inflicting serious injury, one count of having a gun on education property, and one count of discharging a firearm on education property.

Johnson — who was not physically injured — posted short messages on Facebook and Twitter late last night confirming it was his classroom where the shooting took place and saying he was “devastated.” He also wrote on Twitter that he would not speak to any media about the shooting.

“I’m not sure if I want to share anything but clarify any rumors,” Johnson wrote. “My students are special to me and I am devastated.” He announced on social media a month ago that he was accepted into a PhD program at the University of Texas San Antonio in the coming months.

According to UNC-Charlotte officials, the two victims were Ellis Parlier, 19, and Riley Howell, 21. The injured students were Drew Pescaro, 19; Sean Dehart, 20; Emily Houpt, 23; and Rami Alramadhan, 20. The four are expected to make a full recovery.
