Peggy Lynn Warden

SUTHERLAND SPRINGS, Texas - Warden, 56, loved to help other people, said her sister, Leisa Kugler.

"My sister was the most loving and generous Christian woman," Kugler told CNN. "She was a quiet person but she was the center of our family. She was the one we all looked for when something happened. She was the foundation of this family."

Kugler told this story about the photo of Warden shown above.

"The picture that you see where she is holding some branches, she was standing on a roof," Kugler said. "I am terrified of heights but I needed to get these branches cleaned up, so she came over and got up there. ... I was terrified, but that is just who she is. She just loved to help others."
