Evelyn said that that morning, like all mornings, Kenneth Proctor went into building 197 to get breakfast. WJLA reports her saying, "He just went in there in the morning for breakfast. He didn't even work in the building. It was a routine thing for him to go there in the morning for breakfast, and unfortunately it happened."
