Police in Woodruff, South Carolina say 28-year-old Lacey Denise Lamb got behind the wheel in an effort to hinder the arrest of a second passenger who ran from their vehicle during a traffic stop.
Matthew Simmons, 33, bolted from the car where he was chased by responding officer William Knight around 1.40pm on Thursday, according to a police report.

Witnessing the scene was Alisa Thomas who said '[Lamb] went straight towards him,' according to WSPA.
'I knew she was, I mean, like she was going to run over him. So when he fired, he apparently hit her in the head, she lost consciousness and I saw the car just go straight, drive through the underpinning under the trailer,' she said.
Crashed into that trailer was the maroon sedan.
'While chasing Simmons, the female passenger tried to assault the officer with the suspect vehicle. Officer Knight reacted and medical assistance was called,' the police report obtained by GoUpstate.com reads.
