“She was this beautiful, caring, gracious spirit,” said Nicola Heskett, executive director of the center. “That spirit of giving back, she was instilling in her children.”

Co-workers and friends described Ms. LaManno as a consummate nurturer, someone who would shuttle her father-in-law to his doctor’s appointments, and happily take on whatever was asked of her at work.

“Of course she was there seeing her mom because that’s Terri,” Ms. Heskett said. “That’s what Terri did. She took care of everyone.”

Dr. Corporon, too, had made a career out of helping children, often starting at their very first breath. As a family doctor for 30 years in Oklahoma, he was the first to touch scores of newborn babies, his son Will Corporon said Monday.

Dr. Corporon’s own family came first, however. And in 2003, he and his wife left Oklahoma, moving north to be closer to their grandchildren in Johnson County, Kan. (though the family remained devoted fans of the Oklahoma Sooners).

“They were together all the time, my father and Reat, and the other grandkids,” Will Corporon said.

There were 10 grandchildren, and “my father always had one of them with him, or more,” Mr. Corporon said. “He died doing exactly what he wanted.”

Reat had big plans this year.

There was the long-awaited audition for KC SuperStar. But he also had theater productions, in school and out. He was working toward becoming an Eagle Scout and was looking forward to debate camp in the summer.

Somehow, amid all of this, he volunteered at his Methodist church, where he would watch the young children, playing with them or reading Bible stories, while their parents were in services.
