District of Columbia police have identified the suspect who was fatally shot by a security officer at Washington's Union Station after an apparent domestic dispute.

Police on Sunday said 57-year-old William Thomas Wilson Jr. of Washington was the suspect shot Friday. Police said he had stabbed a woman before he was chased and fatally shot.

The violence at the train station frightened commuters Friday, the 14th anniversary of the Sept. 11, 2001, terror attacks.

Police said the security officer who saw the man stab a woman was a private security guard associated with the Securities and Exchange Commission. Police said the suspect turned and pointed the knife at the security guard and lunged at him.

The woman has been hospitalized. Police had no update Sunday on her condition.
