A Liberty woman was arrested on DUI charges late Monday.

Around 9:30 PM, Deputy Jacob Atwood of the Casey County Sheriff’s Office observed a 2010 Hyundai Elantra traveling west on Middleburg Street. The vehicle crossed the center line and was following another vehicle too closely.

Atwood stopped the vehicle on Beldon Street. The driver was identified as 22-year-old Natalie N. Vaughn of Liberty. While speaking with Vaughn, Atwood noticed a marijuana grinder in the center console. When asked if there was anything else in the vehicle, she mentioned there might be alcohol inside.

Deputies searched the vehicle and found a marijuana pipe and several single shots of alcohol. Field sobriety tests indicated impairment.

Deputy Atwood asked when she had last smoked marijuana, and Vaughn stated she had smoked that morning, used a dab pen within the last four hours, and taken half a shot around 12 PM.

Vaughn consented to a field breath test, which showed the presence of alcohol. She was arrested and transported to the Casey County Jail, charged with DUI and following another vehicle too closely.

Deputy Austin Harris and Officer Adam Hewett assisted at the scene.
