Neilie Casey

Neilie Casey, 32, of Wellesley, Mass., had just returned to work at TJX Co. in July from maternity leave and was the mother of 6-month-old Riley.

She was travelling to Los Angeles aboard American Airlines Flight 11 with several other women from TJX to open a new T.J. Maxx outlet.

Casey, a runner and golfer, married her college sweetheart, Michael, and the couple moved to Wellesley. For the past eight years, Casey worked as a merchandise planning manager. “Neilie was such a positive, upbeat and radiant person,” TJX President Ted English wrote in a statement. “She was so bright; nothing was too much for her. She loved to teach. She wore a constant smile.”
