According to the documents, Samantha Petersen said that she had called 911 and then called her sister after the accident.
Eyewitnesses who had been driving on the road told sheriff’s deputies that they had stopped when they noticed the rubble and injured children. One witness said that he had noticed two women, both with blonde hair, who looked similar. One wore a black coat, black leggings and sandals; the other, later revealed to be Samantha Petersen, the driver of the silver S.U.V., wore a red Hy-Vee grocery store uniform, footage from the sheriff’s office later showed.
The woman in the black coat, Sarah Petersen, 35, identified herself to a sheriff’s deputy, and claimed she had been driving the silver S.U.V. When asked for her driver’s license, she said it was in a black S.U.V., not the silver one involved in the crash, raising alarm bells. During an interview in the deputy’s car, she said that, while driving home from a night shift in Rochester, Minn., she had not seen the buggy on the road, and hit it.
The deputy then left the car, but his recorder — which remained on near Ms. Peterson — taped her telling her twin sister that she believed one of the deputies was onto her, according to the complaint. “There’s no way they would ever know the difference between the two of us,” she added, “so they can’t tell.”
But the false story quickly unraveled. An employee at Hy-Vee, where both sisters work, told investigators they had received a hysterical call from Samantha Peterson on the morning of the crash in which she said she was high on methamphetamines and had killed two Amish children.
