MOSSYROCK, Wash. -- The man accused of running over a gas station attendant after refusing to pay for gas told investigators he was trying to rush away from the woman because he thought she was casting a spell on him, according to court documents.

Investigators said Haeng Soon Yang was struck and killed while trying to stop a driver, John Angeline, from driving off without paying for $34 worth of gas outside Flying K store Monday afternoon.

Deputies said the driver ran over Yang with his car, reversed and ran her over again. The second time, the woman's body got stuck under the truck and she was dragged for several feet, deputies said.

After the incident, witnesses said several residents stopped Angeline at a grocery store a half block away. Deputies said a state trooper used a stun gun to subdue and arrest him.

Angeline appeared in court on Tuesday in shackles. He is charged with robbery and second-degree murder. Bail has been set at $500,000.

According to court documents, Angeline told detectives he needed to get away from her because he thought the victim was trying to cast a spell on him.

When asked whether he felt bad about what happened, Angeline said he did not, according to documents.

"I don't know what kind of human being can kill a person like this and go on," said the victim's daughter, Nellie Yang.

Friends of the victim said Yang and her husband immigrated from South Korea and bought the store a few years ago.

Family members said Yang  worked long hours to pay for her children's college tuition. They said everything Yang did was to help her family.

"Everyone loved my mom. She was always smiling. She was everything to me. I loved her so much, and I don't know how I can go on without her," said Nellie Yang.
