A teacher, a donor and 'an angel on Earth'

REYNOLDSBURG, Ohio - Eva Evans is 10 years old and desperately needs a new kidney to live a normal life. Mrs Thomas, a smiling fourth-grade teacher at Eva's school, wants to give her one.

They barely knew each other before. Eva was in a different fourth-grade room down the hall. Tanya Thomas, 48, had spent half her life in the classroom, most of the time right there at Slate Ridge Elementary in the Columbus suburb of Reynoldsburg.

After the usually vivacious Eva started missing school last fall, word got around that she'd been sick for months and probably would need a kidney transplant. A plea for a donor went out on Facebook after no one in her family was viable.
