Erica Ambrose, a senior in the School of Agriculture, told the school's newspaper that she was in class in the Electrical Engineering building when she "heard shouting downstairs and it sounded like people were running through the hallways, just yelling at each other."



"We heard the sirens and we looked out the window to see they had somebody in handcuffs," Ambrose told the Purdue Exponent. "Then, the fire alarms went on to evacuate so we came outside. When we got out, that's when we got the text to avoid the area.



"We didn't actually hear the gunshot," she said. "We just heard yelling."
