The trucker accused of crushing a fourth-year medical student on Interstate 526 earlier this year is back in the Charleston County jail awaiting another bail hearing after serving time for a DUI charge in Georgia.

Arnold Williams, 34, of Salters faces a reckless homicide charge. Williams was charged in the death of Lauren Baccari, 27, who was killed Jan. 28 while sitting in traffic.

Police said Williams was driving too fast for conditions when he hit her from the rear.

North Charleston police originally charged Williams with felony DUI after a witness said he threw a pack of beer over a guardrail after the wreck. Prosecutors could not recommend a more serious charge because police said Williams passed field-sobriety and toxicology tests after the wreck, Solicitor Scarlett Wilson said.

Williams was released on $100,000 bail.

He was arrested again April 6 in Conyers, Ga., after several witnesses said his 2006 Freightliner hauling 26 tons of stone was weaving in and out of traffic on Interstate 20, according to a Georgia state police report. A portable breath test showed a blood-alcohol level of 0.222, according to the report, almost three times the legal limit.

Federal regulators banned Williams from operating a commercial vehicle in interstate commerce in May. The U.S. Department of Transportation’s Federal Motor Carrier Safety Administration declared him an imminent hazard to public safety.

Williams was returned to the Charleston County jail Aug. 28 after serving time for the DUI charge in Georgia. He is up for a bail hearing at 1:30 p.m. Thursday in circuit court. Prosecutors will ask that he remain in jail, Wilson said.
