The chief of police for the University of North Carolina at Charlotte says that the speedy and successful response to the shooting on campus on Tuesday was the direct result of significant training his agency has conducted in recent years to deal with such threats.

According to WSOC-TV, Chief Jeff Baker was about to review the security plan for a concert at the university when the call came in of a possible active shooter on campus. 

Officers rushed into the building where shots had been reported, and at least one officer was able to subdue and take into custody the alleged gunman, identified as 22-year-old Trystan Andrew Terrell.
