"Casey was a beautiful human being with a generous and loving spirit and she touched the lives of everyone she came in contact with," she said.
"Thank you, Casey."

"She said the trip had made her even more determined to take full advantage of the opportunities we have available to us that other nations don’t.
"This reminds me again how her positivity and abundant attitude was always evident in every situation and conversation."
