Inside the Marcus Wesson Massacre

Kiani Wesson, 33, is the oldest girl in the Wesson clan. She bore two girls, Illabelle and Jeva, from her incestuous relationship with her father. Both of her daughters were killed in the suicide pact. Kiani Wesson said she didn't believe the sexual abuse she endured from her father was abnormal because it was all she had ever known. "I thought it was OK because we were being a surrogate mom, a surrogate mother. So that's how I justified it," she said. "I was always afraid to disobey the rules or leave because I felt I would be cursed. To not have my dad's blessings or to not be blessed by Jesus, I didn't want that." (Jay Schadler/ABC News)
