A law enforcement official says the shooter who opened fire in a classroom at Virginia’s Old Dominion University in an attack being investigated as an act of terrorism had a gun with an obliterated serial number. That could complicate efforts to determine how a man with a felony conviction obtained a firearm. The official says investigators will try to re-surface the number in order to trace the gun. The official spoke to the Associated Press on condition of anonymity because they are not authorized to discuss the investigation. The FBI identified the shooter as Mohamed Bailor Jalloh, a former Army National Guard member who pleaded guilty in 2016 to attempting to aid the Islamic State. FBI officials said ROTC students subdued and killed Jalloh to stop the Thursday shooting.
