Tana Boling was crossing the street on her way to Kathleen Edward's grandmother's house on Oct. 13 when Petkov darted out of her driveway.
"Her car was in her driveway. I didn't notice if anyone was inside, it's just there. When I got so far into the street, she came speeding out of her driveway right toward me. If I didn't get out of the way she would have hit me, there is no doubt," Boling told myFOXDetroit.com.
Petkov remains in jail, pending a bond of $75,000 or 10 percent paid for release. She faces up to four years in prison if convicted of felonious driving.
Petkov admitted to posting a picture of Edward's face with skull and crossbones on Facebook, as well as a picture of her mother with the Grim Reaper. She also painted her truck to look like a hearse. Both Kathleen and her mother were diagnosed with Huntington's Disease, a debilitating disorder, which progressively destroys the mind and control of the body.
