Sheriff's deputies are investigating the assault early today of a Mosheim woman who was reportedly knocked unconscious, robbed, and left on the side of a country road.

The victim went "riding around" late Wednesday with two other women, one of whom she knew, Deputy David Love said in a report.

"She said they drove onto Washboard Road and stopped the car and told the victim to get out," the report said. "She said they both attacked her."

The woman the victim did not know struck her with brass knuckles, "knocking her unconscious," the report said.

The report said that when the victim came to, she called her husband, who picked her up and drove her to Takoma Regional Hospital for treatment.

The victim's wallet, containing $100 in cash, credit cards, identification and other personal papers, was left in the car and was stolen.

One female suspect is named in the report.

The woman the victim did not know is described as white, about 5-feet-5 inches tall, with black hair and weighing about 190 pounds.
