Wilson also noted that "all exams will continue as scheduled and I have asked the Division of Academic Affairs to provide accommodations to any students adversely affected by today's incident."
City police officers arrived on the scene quickly, led by Capt. Rick Rutherford. A former SWAT lieutenant trained to handle "active shooter" situations, Rutherford is the deputy commander of the Northeastern District police station — which is adjacent to the campus.
Carter said students were notified through a campus-wide text messaging alert system, emails, Twitter posts and the school's website to stay indoors and lock their doors. He said Morgan has been stressing safety all year through its "See Something, Say Something" campaign, which urges students to text or call in suspicious activity.
"I absolutely believe we're where campus security needs to be," Carter said.
Many students seemed more frustrated than scared at the violence on campus.
"I'm very disappointed to hear the news," said Christian Smooth, 22. "Another bad story at Morgan."
Morgan has also been struggling with a rise in robberies, something the university acknowledged just a day earlier in a public safety update to students. The update said patrols were increased on and around campus after armed robbers held up a student outside Holmes Hall. Later Thursday night, police arrested a person fitting the description of one of the suspects and found him illegally in possession of a handgun.
"We're definitely trying to move up as a campus and develop ourselves as a community, and hopefully people will think this is not the norm," sophomore electrical engineering major Khir Henderson said.
Elaine Smith said city police were overreacting. Her son, a sophomore, was taken into custody as a witness, she said, and she stood outside crime scene tape on Friday asking detectives and officers about him. A detective confirmed to her that he was not a suspect or victim, but no one could tell her where he was.
"I just want to know where my son is at," she said. "They done stormed his dorm. He shot nobody."
Just before 4 p.m., police began winding up crime tape that had cordoned off dorms for several hours, allowing students back in to begin preparing for final exams.
"It's the last day of classes and finals are next week," said sophomore Cavon Caudle, 18. "It's just hard to focus on what we should be focusing on."
