Guy Vaughn Sherrer, 56, was charged with aggravated assault on a pregnant woman.

A Hawthorne man was arrested Sunday after sheriff's deputies say he backed over a pregnant woman with his car.

Guy Vaughn Sherrer, 56, was charged with aggravated assault on a pregnant woman.

At 10:52 p.m. Sunday, Sherrer, while in his vehicle, got into an argument with the woman about a lighter he had left at her home, an Alachua County Sheriff's Office arrest report says.

The woman is eight months pregnant, according to the report.

Witnesses told deputies Sherrer then pulled his car forward to leave and then put the vehicle in reverse and hit the woman with the bumper.

She fell and the vehicle ran over her, causing her to become trapped, the report said.

The woman's fiance pulled her out from under the vehicle, deputies said. The car caused injuries to her back, right arm and leg.

The woman's fiance then took Sherrer's keys and hit him several times to keep him from leaving, the report says. Sherrer was eventually able to get away.

Law enforcement officials found and arrested Sherrer. He admitted he knew the woman was behind the car when he backed up but denied hitting her.

In his booking photo, Sherrer's eyes are black and blue and appear to be swollen shut.

Deputies took him to UF Health Shands Hospital to be medically cleared. After that, he was transferred to the Alachua County jail.

It was unclear Monday whether the woman's fiance will face charges. Sheriff's Sgt. Brett Rhodenizer said the case is still under investigation.

“There is common law in Florida that allows citizens to assist us,” Rhodenizer said. “However, there are additional statutes that govern for excessive force or false imprisonment. Investigators have to find out whether this was an attempt to detain him or if it was retaliation."
