A woman sits in the Chester County jail Tuesday night, charged in what even troopers call a shocking drunken driving incident.

"When you think of a child involved, it's just a shock to the conscious," said South Carolina State Trooper Billy Elder.

Tonja Wilson, 39, of Camden, was stopped early Tuesday morning on Interstate 77 in Chester County.

Troopers said she was drunk, and had a 3-year-old girl in the car with her.

Wilson faces half a dozen charges including driving under the influence with a blood-alcohol level .16 percent or higher, child endangerment, no seat belt, no child restraint, refusing to surrender license or registration and driving under suspension for the second time.

"Stupidity.  Just plain stupidity. I don't know where people's brains are," said Adelaide Kline, who was stopped at an I-77 rest stop near the scene.

Other drivers were shocked at such an arrest involving a child.

"Her license was already revoked, so she had no respect for that obviously. No respect for herself, or her child," said Steve Willard.

Wilson was taken to the Chester County Detention Center, where as of late Tuesday, she was still awaiting a bond hearing.  The little girl in the car with Wilson was handed over to family members.

"She could've killed anybody, and it's the innocent people who always get hurt," said Barbara Willard.

Elder said the case was a reminder of just how dangerous South Carolina roads are.

More than 800 people were killed on the roads last year. More than one-third of all crashes are alcohol-related, troopers said.

Troopers said specific details of the incident involving Wilson have not yet been released, including why troopers first pulled her over.
