When Kimberly came home, Katherine was gone and her husband, Carlos Cardenas was there. When Kimberly asked Carlos where Katherine was, he replied he didn’t know.
Authorities assumed she was a run away until Katherine’s mother found blood in the basement of the house. Testing proved it was Katherine’s.
The disappearance of Katherine came to light when Cardenas was arrested for drunk driving and was found to be illegally in the United States. While he was being detained, investigators questioned him further about Katherine.
