WASHINGTON, D.C. - The Fort Hood shooting was one of five mass shootings that have occurred since President Barack Obama took office.
On Sunday, he and the first lady will meet with families who lost loved ones in the Washington, D.C. Navy Yard Shooting.
They will attend a memorial service for the 12 people killed Monday when former Navy reservist and contractor Aaron Alexis opened fire inside the office where he used to work.
He appears to have fired at people indiscriminately before he was shot and killed by officers.
Two of the victims in Monday's shooting rampage had ties to North Carolina.
Mary Knight grew up in the Fayetteville area – her parents still live there.
John Johnson owned a home in Nags Head and has family in Durham.
Knight and Johnson worked at the Navy Yard in Washington, D.C.
