SANTA ANA (CBS) — A Santa Ana man was in jail Wednesday, accused of raping his stepdaughter and fathering her child.

Mariano Antonio Castro, 56, began molesting the girl on a daily basis when she was 8-years-old who later gave birth to Castro’s child at 11-years-old, according to Santa Ana police. Officials say the molestation occurred between 2001 and 2003.

Police say the crime took place at a Santa Ana apartment where the victim lived with her mother, a sibling and Castro. When the girl reportedly became pregnant at 10 years old, she confided in her mother about the rape. Police say the girl’s mother then kicked Castro out of the home, but he was later allowed to return.
