Local woman assaulted by ex-boyfriend

The Missouri State Highway Patrol was called to what was initially believed to be a traffic crash involving a pedestrian Saturday at 10:09 p.m. near Route C and Big River Road in Washington County.

It is now being investigated as an assault.

When a trooper arrived on the scene a 32-year-old woman was being treated in the back of a Washington County Ambulance.

According to the probable cause statement, 42-year-old Alvin D. Nipper Jr. of Potosi assaulted his ex-girlfriend and fled the scene. The victim stated that she was riding around with Nipper when he became agitated and smacked her in the mouth with his hand.

She stated in the report that Nipper apologized for striking her and stopped his truck so she could clean her face. Nipper stopped his truck on Big River Road near Route C in Belgrade and he then started hitting the victim in her face with his fist. He then tied some type of string around her neck and tried to choke her.

The report said that the victim got out of the truck to wash her face in the river and Nipper followed her out of the truck and stabbed her in the neck and head with a folding knife. She then ran up a steep embankment toward Route C and Nipper got back into his truck and drove toward the victim.

According to her statement as she reached the edge of the pavement on Route C Nipper hit her with his truck. The rear of his truck then hit the concrete bridge rail and he left the scene traveling west on Route C.

On Sunday Washington County deputies were able to locate Nipper at his residence and his truck was found in a wooded area away from his residence. Nipper’s father was identified as the owner of the truck and agreed to let police search it.

The reports stated that when the truck was searched deputies found blood on the interior and exterior of the truck. The blood spots were along the entire driver’s side of the truck from the front bumper to rear bumper. There were also marks consistent with a person’s hand being scraped down the side of the vehicle, along with blood spots. The driver’s side rear taillight was broken and missing. Inside the truck they located the folding knife, a cellular phone charging cord with hair and blue fiber strands attached. 

The victim suffered redness and swelling around her eye, nose and mouth. Her face was also covered in blood and she was bleeding from her forehead and neck where she had cuts. She had a red line around the base of her neck and her right leg was broken. She was later transported by Air Evac to Mercy Creve Coeur.

Nipper is being charged with two counts of Class A felony first-degree assault, one Class B felony of first-degree assault, two felony counts of armed criminal action and one Class A misdemeanor of third-degree assault. Nipper is being held in the Washington County Jail on a $150,000 bond and is to have no contact with the victim if released on bond. 

In addition to those charges, in August another victim reported that Nipper assaulted him by hitting him with a wooden cane and that Nipper was assisted by another person during the incident. The victim was treated at Washington County Hospital for scalp laceration and scalp contusion.
