Kyron's biological mother, Desiree Horman, and his father were officially divorced in February 2003, according to Washington County Circuit Court records.
Carol Moulton said that Kaine, 36, and Terri, 40, have been together for seven or eight years and that they have been married for four or five years. The couple have an 18-month-old girl.
"Terri has raised Kyron," her mother said. "She's been with him since he was an infant. She's as much of a mom as the mom is because the parents had separated about the time that Kyron was born."
