Dallas Police used a remote-controlled robot with an explosive device to kill the suspect.
No students were injured that night, but two campus police officers were wounded. Many credit the former police chief of the college, Joseph Hannigan, for his heroic efforts that night which saved lives.
"He stepped up to the plate, he made sure that the officers who were there knew exactly what they needed to do, he communicated with incoming officers," said Lauretta Hill, current chief of public safety and security for the Dallas College Police Department.
She had not started ad CDPD yet when the shooting happened, but reflected on her former colleague's quick thinking.
