Passerby’s assisted a man who passed out while driving yesterday morning, likely due to an overdose, say Bartholomew County officials.

The incident happened at about 5:48 a.m. yesterday morning at a gas station on North U.S. 31, when witnesses saw an SUV in the driving lane of the gas station with the driver slumped over the wheel and the vehicle still in drive, says Judy Jackson, spokeswoman for the sheriff’s department.

After repeated attempts to wake the driver, the rescuers broke out the rear window and allegedly saw a syringe in the driver’s hand. The driver, 25-year-old Garrett Mack of Greenwood, regained consciousness and deputies arrived. They reportedly saw Mack moving the syringe, which was then on the ground by his foot.

Mack was first treated by Columbus Regional Hospital paramedics, and then arrested on a preliminary charge of possession or use of a legend drug injection device.
