Courageous students at Old Dominion University in Norfolk, Va., subdued and killed a gunman after a shooting that left one dead and two injured Thursday. The suspect, described by authorities as a former National Guardsman, who had served time in prison for abetting ISIS, shouted “Allahu Akbar” before opening fire and killing the instructor of a Reserve Officers’ Training Corps class. The shooting occurred the same day that another Islamic terrorist attacked Temple Israel in Detroit, Mich.

Dominique Evans, special agent in charge of the FBI’s Norfolk field office, praised the ROTC students at a press conference. She said they showed “extreme bravery and courage” by subduing the shooter and preventing others from being killed.

Having killed him without weapons, the students “rendered him no longer alive,” Evans said. “I don’t know how else to say it.”

The incident is being investigated as an act of terrorism.

The gunman has been identified as Mohamed Bailor Jalloh, who Evans said had planned to conduct a terror attack in the style of the Fort Hood shooting in 2009. He had served eight of 11 years of a prison sentence for aiding the Islamic State and was on supervised release, which is similar to probation, when he carried out the attack. The reason for his early release remains unclear.
