The Sioux City community struggles to come to terms with the murders of two young sisters. The suspect, the girls' stepfather Larry Harris told police he was casting a spell that went bad. 

He's in police custody on 2-million dollars bond. While police continue their investigation, they're learning more about how Harris' religious beliefs contributed to the killings. And as KMEG 14's Denise Hnytka reports, that concerns one theological organization.

The story of Kendra and Alysha touches the heart of the Wiccan community. They're saddened by the tragedy and the suspect's suggestion that the girls were killed by witch craft. It's a practice that's often negatively linked to the practice of Wicca.

"The witch is in" sign pokes fun at the stereotypes Dana Peterson knows exist.

"Myths and stereotypes are the things I like to break," said Peterson who practices Wicca. "It's a natural reaction that if you don't know it, you're afraid."

He explains the difference between Wiccan practice and the suspect's account of the murders.

"It's a form of ceremonial magic," said Peterson. "We collect in a circle and use our energy for the best common good. People pray for peace. We cast spells for peace."

Wiccan spells relect their golden rule.

"An' harm it none, do as thou wilt." 

They also believe in the "three-fold law".

Whatever you cast comes back to you 3-fold," said Peterson. "So if we were to cast a spell on death and destruction, think of the consequenes when it comes back 3-fold upon you. Obviously he's getting it. If that's what happened."

Peterson said his heart goes out to the family of Kendra and Alysha. He hopes they find strength in the support of the community. 

Peterson is helping organize a contribution from the Wiccan community to the girls' memorial fund.
