Mary Francis Knight, 51, was killed in the mass shooting at the Washington Navy Yard on September 16, 2013. A resident of Reston, Virginia, Knight worked as an information technology specialist for the Naval Sea Systems Command and taught as an adjunct professor at Northern Virginia Community College.

The shooter was identified as 34-year-old Aaron Alexis, a former Navy reservist working as a contractor at the facility. He used a valid pass to gain entry and carried out an attack that left twelve people dead before Alexis was killed by responding police. FBI investigators later concluded Alexis acted alone; he had sought treatment for mental health problems prior to the attack.

If anyone knew Mary Francis Knight, her work at the Navy facility, or may have seen something relevant that day, please share information with investigators.
