Federal authorities have identified the gunman in a deadly shooting at Old Dominion University in Norfolk, Virginia, as Mohamed Jalloh, a man with a prior federal conviction for providing material support to the Islamic State, according to NBC News.

One person was killed and two others were injured when gunfire broke out on the ODU campus Thursday morning. The shooter is also dead. The FBI has opened a terrorism investigation into the attack.

Jalloh had served time in federal prison for his ISIL-related conviction and had been released before Thursday’s shooting. His prior case placed him on the radar of federal counterterrorism officials, though it was not immediately clear what level of monitoring, if any, he was under in the period leading up to the attack.

ODU police confirmed the shooting and the casualty figures. University officials moved quickly to lock down the campus as law enforcement responded to the scene. Students and faculty received emergency alerts directing them to shelter in place while officers worked to secure the area.

The FBI’s decision to classify the shooting as an act of terrorism signals that investigators believe Jalloh’s prior ideology played a role in the attack, though the agency had not publicly detailed a specific motive or target as of Thursday.

The case raises immediate questions about how federal authorities track individuals convicted of terrorism-related offenses after their release from custody. Jalloh’s prior conviction put him squarely in the category of individuals federal prosecutors have described as posing ongoing national security concerns. Whether conditions of his release included supervision, travel restrictions, or regular check-ins with law enforcement was not disclosed Thursday.

The Justice Department has prosecuted dozens of individuals under material support statutes since the rise of the Islamic State in the mid-2010s. Critics of the system have long argued that the government lacks sufficient resources and legal authority to monitor convicted extremists once their sentences are served. Supporters of tougher post-release restrictions have pointed to cases like this one as evidence that existing tools fall short.

ODU is a public research university with roughly 23,000 students. The campus sits in the heart of Norfolk, a city with a large military and civilian population. Thursday’s shooting sent a ripple of alarm through the broader Hampton Roads region, which encompasses several major Navy installations.

University President Brian O. Hemphill released a brief statement expressing condolences to the victim’s family and pledging cooperation with law enforcement. He did not identify the victim, and ODU police said next-of-kin notification was still underway.

Two injured victims were transported to local hospitals. Their conditions were not released publicly as of Thursday afternoon.

The shooting follows a period of heightened concern among federal law enforcement officials about domestic terrorism threats, including violence inspired by or directly connected to foreign terrorist organizations. FBI Director Kash Patel testified before Congress earlier this year that homegrown extremism tied to groups like ISIL continued to represent a significant threat, even as the organization’s territorial presence in Syria and Iraq had collapsed.

Jalloh’s name had appeared in federal court records tied to his earlier prosecution. The specifics of how he obtained a weapon Thursday and how he gained access to the ODU campus were under active investigation. Federal firearms law prohibits individuals convicted of felonies, including federal terrorism-related offenses, from possessing guns. How he came to be armed is a central question investigators are now pursuing.

For ODU students, many of whom spent hours Thursday locked inside classrooms and dormitories waiting for the all-clear, the attack represented an abrupt and violent disruption to a mid-semester week. Campus counseling resources were made available, university officials said.

Federal investigators from the FBI’s Joint Terrorism Task Force were leading the investigation, working alongside ODU police and other local law enforcement partners. Attorney General Pam Bondi was briefed on the situation, according to a department spokesperson.

The victim who died has not been publicly identified. The investigation is ongoing.
