Millie Chapman’s father Gary Chapman posted on Facebook Tuesday afternoon: "Millie is out of surgery and everything is looking good. She'll be hurting for awhile but healing is underway. Kat is in recovery as well. Thank you all for your prayers and kindness. God is good."

In a note Monday, Gary Chapman said that Millie and Dudley had known each other their entire lives. He wrote that when Dudley needed help, his daughter stepped up and “was a perfect match.”

“I'm so proud of her, words fail me,” he wrote. “Please say a prayer for them both and trust, with me, that they are in His hands.”

Grant also took to Facebook Tuesday to share how proud she was of her daughter Millie.

"We are so proud of Millie's selfless act of friendship," she wrote, "and are grateful that both girls are doing well after yesterday's surgeries."
