People were shocked when a car came flying down an embankment near their home.
"I was real panicked. I couldn't stop shaking," says Kimberly Brock.
Brock says she was at home when Messer's car came down an embankment around 4:30 yesterday afternoon. She recognized the car and jumped in to help when she realized Messer's young twin daughters were inside.
"The baby was laying in the floorboard and it had glass on its head. I just thought, if I move these babies is something going to happen to them? I didn't know what to do," she says.
Kimberly says she and her boyfriend brought the girls inside and waited for help. The twins were airlifted to University of Tennessee Hospital, but Messer is now sitting in the Knox County Jail. The sheriff says she was under the influence of drugs or alcohol when she crashed.
"I feel bad for her, but I feel worse for the kids. As a mother, it's really hard to imagine what was going through her mind, and them poor little babies," says Brock.
There's no word on the conditions of those two girls. Messer faces two counts of wanton endangerment and one count of DUI.
Messer declined WKYT's request for an interview. She was treated for minor injuries.
