Fairchild's fight for her kids began when she was 26-years-old, unemployed and applying for public assistance in Washington state. Everyone in her family had to be tested to prove they were all related.
The Department of Social Services called Fairchild and told her to come in immediately.
"As I sat down, they came up and shut the door, and they just went back and just started drilling me with questions like, 'Who are you?'"
The DNA test results challenged everything she knew about her family. Yes, her boyfriend was the father of the children, and, yes, they were all related, according to the DNA, except for Fairchild. She was told she wasn't the mother.
She knew they were her kids.
She told her parents, who couldn't believe the test results.
"In her blood, she was one person, but in other tissues, she had evidence of being a fusion of two individuals," Uhl said.
It's a rare condition called chimerism
there was proof that Fairchild was her own twin
