An Illinois mother may have just saved the life of a Missouri man and it all started with a Facebook message.
Abbie Dunkle, 35, of Highland, Illinois, donated her kidney to Ryan Armistead, a police officer from Missouri, on Jan. 22. Dunkle had never met Armistead prior to her selfless act.
"She has gone above and beyond for saving my life and giving my wife and son the husband and father that they need and want to be around," Armistead told "Good Morning America" of Dunkle. "I know now that I'll be able to see my son grow up. Before that, I didnt know how old he was going to be before it beat me down. It was scary to think of."
Armistead, a father of one, was diagnosed with a rare auto-immune disorder called IgA nephropathy four years ago. The condition damaged his kidneys and doctors told him he needed a transplant. Armistead's wife, Jessica, then created a Facebook page in hopes of finding him a kidney.
Jessica even made signs, asking for anyone with type O-negative blood to call Barnes-Jewish Hospital in St. Louis, and get tested to see if they're a match.
Dunkle, a mom of two boys, said she always wanted to be a donor, but finally got the opportunity when she came across Armistead's story on the local news.

"It was one of those things where I said well, I'll call the number and see where it takes me," Dunkle told "GMA." "He has a 5-year-old son, which is not that far in age from [my son]. This has kind of been on my heart to do for a while."
With the support of her husband Steve, Dunkle got tested and in December, learned she was a match to be Armistead's kidney donor. She even had the surgery date booked before messaging him on Facebook where she introduced herself and offered him this gift.
"I literally fell to my knees and started crying," Armistead said. "It had been such a long wait and hen Abbie [Dinkle] contacted me she had already done everything 100 percent."
It's been two weeks since the surgery and both families have become fast friends.
"We like to say that we're family now," Dinkle said. "I think everytime I talk to him he thanks me again. He and his family are very thankful."
