Maria Belen Chapur is 43.
She is from Buenos Aires, Argentina, and is a divorced mother of two teenage boys who wants to believe she can still experience true love.
She is an intensely private woman, and one who was not afraid to fight back when she felt that her all-important privacy had been breached.
She was educated in Catholic schools and has professed her belief in God, evil and the afterlife, and yet joined Mark Sanford, a married father of four sons, in violating the Seventh Commandment prohibition against adultery.
Maria Belen Chapur has successfully eluded the news media since the South Carolina Governor publicly and tearfully revealed their yearlong affair last week.
Friends and family have enfolded her and her boys in a protective cocoon, and the only known image of her is a grainy, eight-year-old video from her brief moment in front of the cameras as a television reporter in New York.
Other than a 200-word statement denouncing a hacker's "evil act" of leaking her passionate emails with Sanford, Maria Chapur has maintained her silence.
"I won't speak about my private life as it just belongs to me," she wrote to a former TV colleague, after confirming her affair with Sanford via a statement.
"It has already been made too public in these days, bringing me more pain."
Due partly to the loyalty of friends and family, as well as tougher Argentine privacy laws, relatively little is known about Mark Sanford's "other woman."
In fact, much of what we know about Chapur comes from her own emails, which found their way into the hands of South Carolina's The State newspaper.
