A deadly shooting at Old Dominion University in Norfolk on Thursday, March 12, 2026, left one professor dead and two others injured after a gunman opened fire inside Constant Hall, prompting a rapid response from law enforcement.

Authorities identified the shooter as Mohamed Jalloh, a former member of the U.S. Army National Guard and a naturalized American citizen originally from Sierra Leone. Police fatally shot Jalloh during the incident, bringing the attack to an end.

Investigators revealed that Jalloh had previously been convicted in 2016 for attempting to provide material support to the extremist group Islamic State. According to federal records, he had traveled to Africa in an effort to join the group, provided financial assistance to individuals seeking to join the terrorist organization, and discussed carrying out an attack similar to the 2009 shooting at Fort Hood.

Jalloh later pleaded guilty in federal court and received an 11-year prison sentence. After serving his term, he was released in recent years.
