Randolph worked at the Federal Credit Union in the Murrah Building.
Neace said her sister was in a meeting when the bomb went off at 9:02 a.m.
"She was literally writing on a legal pad, they were preparing for an audit and the floor gave way between them,” Neace said.
Randolph was the 101st person recovered from the basement area, KOKI reported.
Years later, Neace said she wishes she could tell her sister she loves her, and that she's so sorry she wasn't here to be with her family.
Nearly 800 people attended Randolph’s funeral.
"I believe we don't realize the impact of our life, we don't realize the influence we are of just our regular every day, until really something like this happens, and that person is gone and the reality of what their presence meant is really strong," Neace told KOKI.
